I suspect you forget to set the Glance image property needed to tell Nova that it is windows. Specifically it is missing hyperv paravirt <timer>, and many hyperv paravirt <feature> elements. This will make Windows guests unstable and liable to hit BSOD Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
