Hello techs,
We used XL toolkit for Xen hypervisor for starting Windows hvm VMs and the
option rtc_timeoffset worked perfectly with XL. It helped us to set correct
Timezone time/offset for Windows HVM VMs from inside virtual_machine xen config.
For example:
Below option WORKS perfectly with XL toolkit.
[root@hw12xen ~]# cat goillltawdlssq.xl.cfg | grep offset
rtc_timeoffset = "7200" # +2 hours to UTC time (or +/-3600=+/-1 hour to UTC
time)
[root@hw12xen ~]#
Now we try to migrate all the Windows hvm VMs to using Libvirt and Xen 4.6.6 (or
4.4).
But as we see it's impossible to make VMs using correct time/offset set in XML
config like below:
below Libvirt option DOESN'T WORK as we expect...
[root@hw12xen ~]# cat goillltawdlssq.var.xml | grep offset
<clock offset='variable' adjustment='7200' />
[root@hw12xen ~]#
Can you please explain if there's something we're doing wrong way or it's just a
bug like described here:
https://bugzilla.redhat.com/show_bug.cgi?id=1212191 ?
No, you're not doing anything wrong. And yes, you've hit that bug, although I'd
prefer to call it an enhancement request. Xen's rtc_timeoffset setting is
currently not supported by the libvirt libxl driver.
Regards,
Jim
