=== Determining Memory ===
+
=== Prerequisites ===
−
----
 
−
You will need to adjust the memory size to a value that is suitable for your desired maximum resolution using the following formula:
 
  
−
<code>
+
* A working Proxmox install on a computer with 2 GPU's (Tested with 7.1-6)
−
width x height x 4 x 2 = total bytes
+
* A Windows VM with GPU pass-through working (Tested with Win 10)
−
total bytes / 1024 / 1024 = total megabytes + 2
+
* A Linux VM with GPU pass-through working (Tested With Ubuntu 21.10)
−
</code>
+
* Proxmox Host Installed and running on the Windows VM
  
−
For example, for a resolution of 1920x1080 (1080p)
+
During Proxmox 7 lifecycle they shipped a newer OVMF firmware than tested, and breaks '''kvmfr''' module. Currently the workaround is to use an older version of it:
  
−
<code>
+
apt install pve-edk2-firmware=3.20220526-1
−
1920 x 1080 x 4 x 2 = 16,588,800 bytes
+
apt-mark hold pve-edk2-firmware
−
16,588,800 / 1024 / 1024 = 15.82 MB + 2 = 17.82
 
−
</code>
 
  
−
You must round this value up to the nearest power of two, which with the above example would be 32MB
+
For Proxmox 8, the current pve-edk2-firmware version 3.20230228-4 is tested to work with kvmfr 0.0.9 with Linux 6.4.3 in Linux VM. If you used the workaround mentioned above, you can revert it by:
  
−
It is suggested that you create the shared memory file before starting the VM with the appropriate permissions for your system, this only needs to be done once at boot time, for example (this is a sample script only, do not use this without altering it for your requirements):
+
apt-mark unhold pve-edk2-firmware
 +
apt full-upgrade
  
−
<code>
+
=== Windows VM setup ===
−
touch /dev/shm/looking-glass && chown user:kvm /dev/shm/looking-glass && chmod 660 /dev/shm/looking-glass
 
−
</code>
 
  
−
== Looking Glass Service (Windows) ==
+
Using the Proxmox GUI, Set the Windows VM Display to "none"
 +
 
 +
Then in a shell to the Proxmox host edit the Windows VM Config:
 +
<syntaxhighlight lang=bash>
 +
nano /etc/pve/qemu-server/**YOUR-WINDOWS-VM-ID**.conf
 +
</syntaxhighlight>
 +
And add the following arguments to the args: line. If the args: line doesn't exist, create it at the top of the config.
 +
<syntaxhighlight lang=bash>
 +
-device ivshmem-plain,memdev=ivshmem,bus=pcie.0 -object memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=32M -device virtio-mouse-pci -device virtio-keyboard-pci -spice 'addr=0.0.0.0,port=[spice port],disable-ticketing=on' -device virtio-serial-pci -chardev spicevmc,id=vdagent,name=vdagent -device virtserialport,chardev=vdagent,name=com.redhat.spice.0
 +
</syntaxhighlight>
 +
The -device virtio-mouse-pci -device virtio-keyboard-pci are not strictly necessary but should reduce input latency.
  
−
You must first run the Windows VM with the changes noted above in either the [[Installation#libvirt_Configuration|libvirt]] or [[Installation#Qemu_Commands|Qemu]] sections.
+
[spice port] should be replaced by a tcp port not in use.
  
−
=== Installing the IVSHMEM Driver ===
+
Boot the Windows VM
−
----
 
−
Windows will not prompt for a driver for the IVSHMEM device, instead, it will use a default null (do nothing) driver for the device. To install the IVSHMEM driver you will need to go into the device manager and update the driver for the device "PCI standard RAM Controller" under the "System Devices" node.
 
  
−
A signed Windows 10 driver can be obtained from Red Hat for this device from the below address:
+
=== Linux VM setup ===
  
−
https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/upstream-virtio/
+
In a shell to the Proxmox host edit the Linux VM Config:
 +
<syntaxhighlight lang=bash>
 +
nano /etc/pve/qemu-server/**YOUR-LINUX-VM-ID**.conf
 +
</syntaxhighlight>
 +
And add the arguments to the args: line. If the args: line doesn't exist, create it at the top of the config.
 +
<syntaxhighlight lang=bash>
 +
-device ivshmem-plain,memdev=ivshmem,bus=pcie.0 -object memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=32M
 +
</syntaxhighlight>
 +
Then boot the Linux VM, and download the latest Looking-glass source from https://looking-glass.io/downloads (Tested with version B5.0.1)
  
−
Please note that you must obtain version 0.1.161 or later
+
Follow the Official Looking-glass documentation on how to Build Looking-Glass Client - https://looking-glass.io/docs/B5.0.1/build/#building
  
−
=== Using the Windows Host Application ===
+
Follow the Official Looking-glass documentation on how to install the kernel module - https://looking-glass.io/docs/B5.0.1/module/
−
----
 
−
Start downloading the correct version for your release from https://looking-glass.hostfission.com/downloads. You can either choose between '''Official Releases''' which is is stable or '''Release Candidates''' that tries to be stable but has new features. '''Note:''' If your '''looking-glass-client''' was created by building from the '''master branch''' you have to pick the '''Bleeding Edge''' version.
 
  
−
The windows host application captures the windows desktop and stuffs the frames into the shared memory via the shared memory virtual device, without this Looking Glass will not function. It is critical that the version of the host application matches the version of the client application, as differing versions can be, and usually are, incompatible.
+
=== Running Looking-Glass ===
  
−
To get the Windows-Host-Application running after restart you need to run it as a privileged task we do that by starting '''cmd.exe''' as '''administrator''' and running a command in it which creates a windows task.
+
# Make sure both VMs are running.
−
<syntaxhighlight lang=batch>
+
# On the Linux VM, open a terminal and cd to the looking glass client build folder
−
SCHTASKS /Create /TN "Looking Glass" /SC ONLOGON /RL HIGHEST /TR C:\Users\<YourUserName>\<YourPath>\looking-glass-host.exe
+
# Run Looking-Glass with:
 +
<syntaxhighlight lang=bash>
 +
  ./looking-glass-client -f /dev/kvmfr0 -c **Your_Proxmox_Host_IP** -p **spice port specified**
 
</syntaxhighlight>
 
</syntaxhighlight>
  
−
Copy the following command in to your cmd shell and replace the '''<YourUserName> ''' with your username  '''(e.g. "games")''' and your '''<YourPath> ''' with the part where the looking-glass-host.exe is stored '''(e.g. "Documents")''' .
+
=== Using vGPU merged driver to run Looking Glass on Proxmox Host ===
  
−
[[File:Screenshot_cmd_windowstask.png|500px]]
+
This currently only work for Windows guest, as Looking Glass Linux Host is immature at the moment.
  
−
Now you simply need to hit enter in to the cmd shell and restart the vm to test if it worked.
+
You can simplify the guest set up by replacing the IVSHMEM settings in <code>args</code> with the following line:
 +
<syntaxhighlight lang=bash>
 +
ivshmem: size=32
 +
</syntaxhighlight>
 +
This will create a 32M IVSHMEM file under <code>/dev/shm/pve-shm-**VMID**</code>. You will need to point <code>app:shmFile</code> to this file when launching LG client.
  
−
== Running the Client ==
+
If you want to run a Linux VM with GPU passthrough, but also being able to LG into this Windows guest in addition to from Proxmox host, you can add the following line in VM config file:
 +
<syntaxhighlight lang=bash>
 +
ivshmem: size=32,name=**WINDOWS-VMID**
 +
</syntaxhighlight>
 +
This will override Proxmox to open <code>/dev/shm/pve-shm-**name**</code> instead, and since the default for **name** is **VMID**, set that to your Windows's VMID does the trick.
  
−
The client command is the binary file: '''looking-glass-client'''. This command should run after the Windows Host Application has started.  
+
Additionally you can use UNIX socket for SPICE instead of opening another port on Proxmox. This file cannot be accessed by Linux guest so only do this if you don't need access Looking Glass from another VM.
 +
<syntaxhighlight lang=bash>
 +
-spice unix=on,addr=/run/lg**YOUR-WINDOWS-VM-ID**.socket,disable-ticketing=on
 +
</syntaxhighlight>
  
−
For an updated list of arguments visit:
+
However, those 2 files will be created as root-owned. You will need to create a hook script to set the correct permissions for them (/etc/tmpfile.d was having reliability issue on my machine for IVSHMEM file, and it cannot override socket file's ownership at all):
−
https://github.com/gnif/LookingGlass/blob/master/client/README.md
 
  
−
Common options include '-s' for disabling spice, '-S' for disabling the screen saver, '-F' to automatically enter full screen and '-k' to disable the UPS/FPS rate.
+
<syntaxhighlight lang=bash>
 +
# 3rd party script, created by the community, not part of Looking Glass project!

Revision as of 05:42, 4 May 2024

The Official Documentation contains installation instructions for Debian-based distributions and should work fine on derivatives. The following are supplemental guides for other distributions, which do not work using the Debian instructions.


Fedora 35+

Installing Dependencies for Client Build

dnf install cmake gcc gcc-c++ libglvnd-devel fontconfig-devel spice-protocol make nettle-devel \
            pkgconf-pkg-config binutils-devel libXi-devel libXinerama-devel libXcursor-devel \
            libXpresent-devel libxkbcommon-x11-devel wayland-devel wayland-protocols-devel \
            libXScrnSaver-devel libXrandr-devel dejavu-sans-mono-fonts

For wayland support you will also need the following packages 

dnf install libdecor-devel

For audio support in Bleeding Edge, the following packages should also be installed:

PipeWire users: 

dnf install pipewire-devel libsamplerate-devel

PulseAudio users: 

dnf install pulseaudio-libs-devel libsamplerate-devel

Installing Additional Dependencies for Kernel Module Build

dnf install dkms kernel-devel kernel-headers

OpenSuSE Leap 15.0+

Installing Dependencies

zypper install binutils-devel make cmake fontconfig-devel libSDL2-devel libSDL2_ttf-devel spice-protocol-devel libX11-devel libnettle-devel wayland-protocols-devel \
               libconfig-devel libXi-devel libXss-devel libwayland-egl-devel nettle

Tumbleweed

For Tumbleweed this should do the trick: 

zypper in binutils-devel clang cmake dejavu-sans-mono-fonts fontconfig-devel gcc gcc-c++ glibc-all-langpacks libdecor-devel libglvnd-devel libnettle-devel libpulse-devel libsamplerate-devel libSDL2-devel libSDL2_ttf-devel libvulkan1 libwayland-egl-devel libxkbcommon-devel libXpresent-devel libXrandr-devel libXScrnSaver-devel libXss-devel make Mesa-libGLESv3-devel nettle-devel pipewire-devel pkgconf-pkg-config pkgconfig spice-protocol-devel vulkan-loader wayland-devel zlib-devel-static

Arch Linux / Manjaro

Installing Dependencies for Client Build

pacman -Syu cmake gcc libgl libegl fontconfig spice-protocol make nettle pkgconf binutils \
            libxi libxinerama libxss libxcursor libxpresent libxkbcommon wayland-protocols \
            ttf-dejavu libsamplerate

Installing Additional Dependencies for Kernel Module Build

pacman -Syu dkms linux-headers

Void Linux

Installing Dependencies

xbps-install -Syu binutils-devel cmake freefont-ttf fontconfig-devel SDL2-devel SDL2_ttf-devel spice-protocol libX11-devel libXpresent-devel libXinerama-devel nettle-devel \
                  gcc make pkg-config

Gentoo

Installing Dependencies

First set up the necessary USE flags if needed: 

echo "media-libs/libsdl2 gles2" >> /etc/portage/package.use/libsdl2
echo "media-libs/nettle gmp" >> /etc/portage/package.use/nettle

Then fetch the packages: 

emerge sys-devel/binutils dev-util/cmake media-fonts/freefonts media-libs/libsdl2 media-libs/sdl2-ttf app-emulation/spice-protocol \
       media-libs/fontconfig dev-libs/nettle media-libs/libsamplerate \
       media-libs/glu

This list can also be placed into a setfile in /etc/portage/sets/ so that they can be updated with 

emerge @setfile

Proxmox

Prerequisites

  • A working Proxmox install on a computer with 2 GPU's (Tested with 7.1-6)
  • A Windows VM with GPU pass-through working (Tested with Win 10)
  • A Linux VM with GPU pass-through working (Tested With Ubuntu 21.10)
  • Proxmox Host Installed and running on the Windows VM

During Proxmox 7 lifecycle they shipped a newer OVMF firmware than tested, and breaks kvmfr module. Currently the workaround is to use an older version of it: 

apt install pve-edk2-firmware=3.20220526-1
apt-mark hold pve-edk2-firmware

For Proxmox 8, the current pve-edk2-firmware version 3.20230228-4 is tested to work with kvmfr 0.0.9 with Linux 6.4.3 in Linux VM. If you used the workaround mentioned above, you can revert it by: 

apt-mark unhold pve-edk2-firmware
apt full-upgrade

Windows VM setup

Using the Proxmox GUI, Set the Windows VM Display to "none"

Then in a shell to the Proxmox host edit the Windows VM Config: 

nano /etc/pve/qemu-server/**YOUR-WINDOWS-VM-ID**.conf

And add the following arguments to the args: line. If the args: line doesn't exist, create it at the top of the config. 

-device ivshmem-plain,memdev=ivshmem,bus=pcie.0 -object memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=32M -device virtio-mouse-pci -device virtio-keyboard-pci -spice 'addr=0.0.0.0,port=[spice port],disable-ticketing=on' -device virtio-serial-pci -chardev spicevmc,id=vdagent,name=vdagent -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

The -device virtio-mouse-pci -device virtio-keyboard-pci are not strictly necessary but should reduce input latency.

[spice port] should be replaced by a tcp port not in use.

Boot the Windows VM

Linux VM setup

In a shell to the Proxmox host edit the Linux VM Config: 

nano /etc/pve/qemu-server/**YOUR-LINUX-VM-ID**.conf

And add the arguments to the args: line. If the args: line doesn't exist, create it at the top of the config. 

-device ivshmem-plain,memdev=ivshmem,bus=pcie.0 -object memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=32M

Then boot the Linux VM, and download the latest Looking-glass source from https://looking-glass.io/downloads (Tested with version B5.0.1)

Follow the Official Looking-glass documentation on how to Build Looking-Glass Client - https://looking-glass.io/docs/B5.0.1/build/#building

Follow the Official Looking-glass documentation on how to install the kernel module - https://looking-glass.io/docs/B5.0.1/module/

Running Looking-Glass

  1. Make sure both VMs are running.
  2. On the Linux VM, open a terminal and cd to the looking glass client build folder
  3. Run Looking-Glass with:
 ./looking-glass-client -f /dev/kvmfr0 -c **Your_Proxmox_Host_IP** -p **spice port specified**

Using vGPU merged driver to run Looking Glass on Proxmox Host

This currently only work for Windows guest, as Looking Glass Linux Host is immature at the moment.

You can simplify the guest set up by replacing the IVSHMEM settings in args with the following line: 

ivshmem: size=32

This will create a 32M IVSHMEM file under /dev/shm/pve-shm-**VMID**. You will need to point app:shmFile to this file when launching LG client.

If you want to run a Linux VM with GPU passthrough, but also being able to LG into this Windows guest in addition to from Proxmox host, you can add the following line in VM config file: 

ivshmem: size=32,name=**WINDOWS-VMID**

This will override Proxmox to open /dev/shm/pve-shm-**name** instead, and since the default for **name** is **VMID**, set that to your Windows's VMID does the trick.

Additionally you can use UNIX socket for SPICE instead of opening another port on Proxmox. This file cannot be accessed by Linux guest so only do this if you don't need access Looking Glass from another VM. 

-spice unix=on,addr=/run/lg**YOUR-WINDOWS-VM-ID**.socket,disable-ticketing=on

However, those 2 files will be created as root-owned. You will need to create a hook script to set the correct permissions for them (/etc/tmpfile.d was having reliability issue on my machine for IVSHMEM file, and it cannot override socket file's ownership at all): 

# 3rd party script, created by the community, not part of Looking Glass project!
# Assuming you have set up a storage named `local-btrfs` and is mounted at `/var/lib/pve/local-btrfs`
