Updating to 25.04 breaks my VMs. Both Windows and Linux machines show "Session aborted."
sudo rmmod kvm_amd kvm
fixed it for me. 

sudo rmmod kvm_intel kvm
fixed it for the user on the forum where I found a question about the problem. That user was on Fedora It seems problem is since kernel 6.12.4. I am on 6.14.0-15
