    Virt Manager and using remote hosts over SSH - X windows STALL

    Hey!

    I'm using this setup for years:
    • I have a number of physical hosts with Ubuntu 18.04 and KVM VMs
    • each KVM VM host hosts about 4 to 8 VMs
    • my host is ubuntu 19.10
    • everything updated to the latest pach sets
    • my host connects through OpenVPN to the network with the VM hosts.
    • I have a virt-manager setup that uses SSH to connect to these KVM hosts


    So when I launch virt-manager and it connects to all VM hosts and gets all VM details the X environment of my machine just stalls until virt-manager is done with its thing. Remember the times of Windows 98, single thread CPUs and loading the CDROM? That's exactly that. Once it gets all data from remote hosts, I can work.

    What looks like the main problem is that the gnome-shell process starts using all of it's CPU core, when virt-manager builds its UI with data from the remote hosts.

    Tried googling for solutions, and people seem to have problems with this, but I found zero solutions.

    I'm using Xorg and nvidia binary drivers.

    I understand, that there might be some networking issue that makes the virt-manager wait for something too long, but still this should not stall the X environment.

    Any ideas what I can look into?

    I've found a workaround.

    You need to disable the tray icon of virt-manager within its options. This makes the problem go away.

    I guess I've used this forum as a rubber ducky. Maybe someone will find this helpfull in the future...
