[Xen-users] Time change conundrum
Here's a confusing issue for you, I have a bunch of machines running
Xen 4.1.
The time in the BIOS was wrong at machine power on, so logically, I
set the time in
Dom0 with NTP and synced it back to the hardware clock (just in
case). I restart the
VMs which came up before the time changed, so that they would get
the correct time
on startup (as has always worked in the past with Xen 3.x).
The VMs do *not* come up with the initial clock set by the system
clock in Dom0, they
persist in using the time before it was set on the host system (plus
however many
seconds/minutes etc.) have passed, so the original clock time on
Dom0 is ticking along
somewhere even though every utility in the system seems to report
the 'correct' time
as I have set by NTP.
Any ideas? I'm at my wit's end with it, I've tried different kernels
(albeit with [almost] the same
config), both jeremy-git-xen-next-2.6.32 and linux 3.1.0+ (latest
from git). I've tried with different
Xen version 4.1.0/4.1.1/4.1.2 and the problem exists in each of
them.
I know that I can run NTP in each VM, but I'd like the system time
to be correct at boot up as it
will make the timestamps in the logs very confusing when it jumps
back an hour.
