Boot 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 kernal modual kernel module - https://looking-glass.io/docs/B5.0.1/module/

# Make sure both VMs are running. # On the Linux VM, open a terminal and cd to the looking glass client build folder # Run Looking-Glass with:<syntaxhighlight lang=bash> ./looking-glass-client -f /dev/kvmfr0 -c **Your_Proxmox_Host_IP** -p **spice port specified**</syntaxhighlight> === 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 <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. 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. 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> 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):
