So this is a KVM bug, and you have sent a patch to= kvm > to fix this bug, right? As I noted, at some point I did not manage to reproduce the failure. The failure on bare-metal that I experienced hints that this is either a te= st bug or (much less likely) a hardware bug. But I do not think it is likely t= o be a KVM bug. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
