I wish to set the virtualized hardware time to a fixed value upon bootup. In Qemu, this is easy:
qemu-kvm \
-rtc base=2011-11-11T11:11:00 \
…
However I fail to see a way of adding this to a guest configuration in libvirt (v2.2.0). Some of the parameters of Qemu appear to be supported, but it would appear that date is not among them. Is there another way?
