I was wondering what the safest way would be to screenshare dom0 inside of a VM. I was thinking about getting a capture card to use and pass the USB through to a VM, but that may not work and need PCIE USB card passthrough, which is inconvenient. Does anyone have any ideas?
qubes-video-companion works. It will capture dom0 desktop and return it to the VM.
There’s GitHub - QubesOS/qubes-video-companion . And currently using it to screenshare dom0 needs troubleshooting: Qubes-video-companion unable to share dom0's screen - #2 by augsch .
