Hi everyone, Hope this is the right place for this .. I have been using kvmtool as it seems nicely lightweight compared to qemu. However certain workloads - specifically the Debian/Ubuntu install / dist-upgrade process - seem to trigger hangs of the guest; most obvious symptom is the console stops echoing keystrokes. This is on Ubuntu 18.04/x64, but I have tried building kvmtool from git with no improvement. I'm using the Ubuntu kvm kernel in the guest and the regular generic one on the host; both of these are based on 4.15.18 currently by the looks of it. I so far haven't managed to reproduce this using qemu, so I'm assuming it's kvmtool specific. Any suggestions on possible configuration problems, or how I can help to debug further? Thanks, Steve
