Umm, I have a problem with that statement. Anything that requires guest interaction (which guest-agent set-time does) must NOT default to being automatic; it is only safe to enable if explicitly allowed. What is the domain XML that must be explicitly set in order to turn on automatic time-set after resume? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
