However, this is not acceptable for a backup.
"virsh shutdown" should work, provided you have a new enough version of libvirt (what version are you using?), you have the <acpi/> tag set in the libvirt XML, and your guest (what kind of guest is it?) is using ACPI. virsh shutdown works by sending an ACPI event to the guest, basically equivalent to hitting the soft power button on a piece of hardware. In recent testing, I was able to use virsh shutdown to shut down basically any 2.6 based Linux guest, and any Windows guest using ACPI. That said, doing the backup "inside" the guest, as suggested by Javier, is probably a better solution. -- Chris Lalancette -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
