Hey hey,

I have a Multi Controller-Compute(KVM)-Networke(Neutron) Environment based on Ubuntu 14.04 with Juno.

My problem is, that Windows VMs get the wront Time from Timeserver. I can set the time manually and reboot and the Time seams okey, but when i do a shutoff and then reboot the machine, I get the wrong time again... I belive it has nothing todo with the timezone in the VM.

My question is, where get the Instance the time from ?

Thanks for helping me !

Regards rahuk

Soooo, now i have found the answer... you can set the os_type for images to "windows"

# glance image-update --property os_type="windows" <IMAGE-ID>

If you now boot the Image the time will be correct...

But whats with VMs already installed ?

Hack your Database!

# mysql -u root -p
$ use nova;
$ UPDATE instances set os_type='windows' where hostname='uhrzeit-test';
$ select hostname,os_type from instances WHERE hostname='uhrzeit-test';
+--------------+---------+
| hostname     | os_type |
+--------------+---------+
| uhrzeit-test | windows |
+--------------+---------+

Make a reboot of your VM and the time will be displayed correct !
