Subject: comprehensive documentation of clock-related options for HVM guests
Date: Mon, 16 Feb 2009 11:39:31 +0100 [thread overview]
Message-ID: <49994263.5080507@inria.fr> (raw)
Hello list.
Despite using ntp, we're facing heavy clock skews on our HVM guests,
which happen to be almost all x86_64 linux. I've been browsing the list
archive, I found reference to two different xen guest configuration options:
- timer_mode
- hpet
However, I couldn't find neither reference documentation, neither on
their default values.
According to this tread, the default for timer_mode was changed in some
part of the source tree from 0 to 1:
http://lists.xensource.com/archives/html/xen-devel/2008-10/msg00261.html
But according to this one, there was a discussion for changing
timer_mode from 0 to 2, and hpet from 0 to 1:
http://lists.xensource.com/archives/html/xen-devel/2008-06/msg00095.html
And according to XendConfig.py code (3.3.1), the default value for both
of them is actually 0...
This is a bit confusing :(
