Haven't seen mention of this elsewhere yet, not sure if this is the best place to post it.
I just updated to libvirt-3.0.0-1 on Arch from libvirt-2.4.0-2 and my Windows VMs no longer start. Reverting to libvirt-2.4.0-2 reverses the problem. The problem affects Windows 7 and XP, the XP machine doesn't have GPU passthrough. A CAELinux VM still runs. journalctl shows, under libvirtd 3.0.0 Jan 26 06:46:35 bozo systemd[1]: Started Virtual Machine qemu-1-Windows7.

I found this https://www.redhat.com/archives/libvir-list/2016-October/msg00745.html, implementing a new libssh transport. Suggestions? Places to post this error other than here? I realize this isn't probably a vfio related bug. _______________________________________________ vfio-users mailing list [email protected] https://www.redhat.com/mailman/listinfo/vfio-users
