I'm still having problems with this. I've dug around and found errors in
the qemu-dm log.
When I try to start the VM with libvirt, the error I'm getting is:
"xs_read(/vm/414e73de-cf1e-487c-87e0-d4ebf7a23576/rtc/timeoffset): read
error"
I did a xenstore-ls on the /vm/414e73de-cf1e-487c-87e0-d4ebf7a23576
directory and sure enough, rtc/timeoffset is not there. When I start the VM
with the Xen config file I used to generate the XML the rtc/timeoffset is
there (timeoffset is set to "0").
Is there a way to set that in the XML? I didn't see it in the online XML
description.
I'm using a slightly different XML description than I had originally so I've
included here (along with the Xen Config file)
Thanks!
