It appears that increasing the graphical ram in the Video QXL device may have helped, due to the nature of the issue it's hard to say for sure but will report back.
To be clear, I would still consider this a bug to at least fail with a segfault as opposed to a more reasonable error report if there were issues with not having enough graphical-related ram. Ideally, there shouldn't be any issue with the default settings KVM/Libvirt/virt- manager sets up for you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095065 Title: Frequent spice agent crashes as KVM/Libvirt guest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-qxl/+bug/2095065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
