I have the same issue. I have assumed it was a Windows configuration
issue. I have relied on sync'ing to Internet Time upon each bootup. It
would be nice to find a solution to this. My Windows VM consistently
comes up exactly 5 hours off, and although NTP is configured the time is
never corrected until I manually sync to Internet Time. It certainly
appears to be using the wrong TZ (GMT).

Setting vm_dynamic.utc_diff to 3600 (+1) did the trick for me.
But that is no real solution. And what about daylight saving times...?
memo for myself:
Stop VM.
# su - postgres
# psql
# \c engine
# select a.vm_name,b.utc_diff,a.vm_guid from vm_static a, vm_dynamic b wher=

# update vm_dynamic set utc_diff=3D3600 where vm_guid=3D'...';
# commit;
Afterwards start VM.

I'll be happy to try a patch, if you can deliver it in a convenient way
for me to install.
The bug comments and synopsis are misleading so at first I didn't think
this was it. The bug specifically says "Time is off by exactly 1 or 3
hours, depending on VM" and the synopsis says "time is off by as much as
3 hrs".
My time is currently 4 hours off (I think it was 5 before Daylight
Savings Time).
The release note text states the issue correctly though, I think.
The only thing giving me any doubt is that all my non-Windows VMs are
fine. The problem is isolated to Windows guests.

I implemented the above patch on one of our hypervisor nodes. But this
does not change anything. The VM has always the time difference after reboot
that is set in table vm_dynamic.
That patch is not intended to change this fact. What it should do is
report a correct timeOffset once your guest OS syncs its time.
We are on GMT+1. if utc_diff = 0 Windows VM time is on hour back. If
utc_diff = 3600 Windows VM time matches.
Should I file a new BZ?
I'd prefer to make sure we have all the facts first. Would you boot your
VM, and report the vmCreate line from vdsm.log?
The, fix the timezone withing the guest, and report the rtc events from
the log, and the timeOffset reported by `vdsClient -s 0 getAllVmStats`.
Stop the VM and check if Engine's utc_diff has changed.
A detailed BZ report is worth its weight in gold ;-)

Marcus,
Are all your VMs Windows? Because I have a mix and only Windows VMs are
affected. Seems like changing utc_diff should only be done for Windows VMs
(Linux happy to work with a hardware clock of GMT).

Hi Dan,
just saw the bug update with target 3.4.1. Could you
reproduce the bug and do you have some advice how to
handle that setting until then? And what should I expect
when daylight saving takes place in march?
From my understanding I would:
- pin all VMs to utc_diff=3600 (GMT+1) now
- pin all VMs to utc_diff=7200 (GMT+2) after change of summertime

Hello,
you are right. Only Windows VMs show that behaviour. But for Linux the
problem is even more strange: Have a look at my database for a specific
Linux VM:
engine=3D# select a.vm_name,b.utc_diff from vm_static a, vm_dynamic b where=
a.vm_guid=3Db.vm_guid;
vm_name | utc_diff
------------------+----------
colvm53 | -271973
Logging into the VM it shows the correct time but the hardware clock is far=
away according to utc_diff:
colvm53:~ # hwclock
Tue Feb 4 12:49:21 2014 -0.173138 seconds
colvm53:~ # date
Fri Feb 7 16:20:42 CET 2014
Maybe because it reads the KVM/QEMU timing values another way than Windows.

Hi Dan,
just saw the bug update with target 3.4.1. Could you
reproduce the bug and do you have some advice how to
handle that setting until then? And what should I expect
when daylight saving takes place in march?
From my understanding I would:
- pin all VMs to utc_diff=3600 (GMT+1) now
- pin all VMs to utc_diff=7200 (GMT+2) after change of summertime

<br>
you are right. Only Windows VMs show that behaviour. But for
Linux the <br>
problem is even more strange: Have a look at my database for a
specific<br>
Linux VM:<br>
<br>
engine=# select a.vm_name,b.utc_diff from vm_static a,
vm_dynamic b where a.vm_guid=b.vm_guid;<br>
vm_name | utc_diff<br>
------------------+----------<br>
colvm53
| -271973<br>
<br>
Logging into the VM it shows the correct time but the hardware
clock is far away according to utc_diff:<br>
<br>
colvm53:~ # hwclock<br>
Tue Feb 4 12:49:21 2014 -0.173138 seconds<br>
colvm53:~ # date<br>
Fri Feb 7 16:20:42 CET 2014<br>
<br>
Maybe because it reads the KVM/QEMU timing values another way
than Windows.<br>

Have you tried changing utc_diff for a Linux VM, to see if that has
any effect?<br>

No, I did not reproduce the bug myself. I believe that your report is
true and asked Michal to get it fixed by ovirt-3.4.1 (frankly, let's ask
to fix it earlier!)
I have no intermediate remedy, save for manually editing utc_diff.
And what should I expect
when daylight saving takes place in march?

Yes, assuming that the local admin of the VM do not want to change their
timezone - in Windows it means an update of the rtc, which is not saved
properly in Engine.
