But is that true both for the 'guest-set-time' no-arg case (which tells the guest to read the current RTC and update in-memory time accordingly), as well as the 'guest-set-time with time argument' case (which tells the guest to forcefully set in-memory time, then write that time back to the RTC)? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
