I am moving almost all of my infrastructure servers to virtualized ones. Even my firewall is virtualized now. But I am experienced these random lockups now and then. Will apply the patch and test it again.
I do have another issue with running an OpenBSD guest in which it wont do interrupt remapping so I have to enable an unsafe behavior on kvm which allows it to do pci passthrough with "unsafe" interrupts. There are some issues using this in which a privileged user in the guest machine could escalate it's privileges on the host and/or crash it. Anyway, this isn't a problem for me right now, when I do have some time I'll look into it. Thanks, -- Giancarlo Razzolini GPG: 4096R/77B981BC
