Hi, I am using libvirt with qemu/kvm with qemu-guest-agent and suspend/save/resume linux and windows vm's. Time in Windows gets handled fine with ntp but I can get neither ntp or chrony to sync after resume without manually setting the time close to correct first.
Searching has gotten me to the point where I can manually set the time using qemu-guest-agent but I cant figure out how to get libvirt to automaticly trigger this on resume. I am finding information saying it works but not how, or that its still work in progress and not implemented yet (but patches exist). Can someone either say "its not working yet" or explain what I am missing please?
What version of libvirt are you using? Since 1.2.5 there's virDomainSetTime() API that can do this and since 1.2.8 it's called automatically after resume.
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
