I'm runing ubuntu 20.04 on the host and Ubuntu 20.10 on two VMs. I always let them open and running. Sometimes, after waking the laptop from sleep, one of them has the screen locked (they both are configured to never lock screen/sleep). Then I put the password and unlock it, the screen gets black and I have to force reset the VM for it to work again.
It's annoying because I then have to reopen everything I was working on.
What can I do to solve this problem? It's not always that it happens and not on both VMs at the same time.
I use virt-manager for the virtualization
