[libvirt-users] How to set manually starting date/time for guest kvm

[Aleksei]

It doesn't seem to be implemented in libvirt's XML.

You can still try and hack it though:

<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<qemu:commandline>
     <qemu:arg value='-rtc base="xxx"'/>
   </qemu:commandline>
</domain>

It will mark this domain "tainted" in libvirt's log.
