how to change HVM timezone with qvm-prefs

[wyory]

Hi,

How do I set the HVM clock timezone?

According to this https://www.qubes-os.org/doc/Dom0Tools/QvmPrefs/ I
should be able to do it with qvm-prefs. I can set positive values, but
then my HVM won't start. I can't set negative offset (which is what I
need), and I can't set it back to localtime.

qvm-prefs -s hvmname timezone localtime
Invalid timezone value!

qvm-prefs -s hvmname timezone -3600
qvm-prefs: error: no such option: -3

After changing it to a positive integer, I can't start my HVM. I get:
AttributeError: 'int' object has no attribute 'lower'

Ough, this looks like really dumb bug. Especially that with 'localtime'

Thanks for creating the ticket. This is a HVM template by the way.

I was able to start the HVM template again by manually setting timezone
to localtime in /var/lib/qubes.xml

But if I try setting the value ion qubes.xml to the negative offset I
need I get "libvirt.libvirtError: unsupported configuration: unknown
clock basis 'UTC'"
