Subject: Clock off in guest
Date: Wed, 13 Feb 2008 10:41:44 +0100	[thread overview]
Message-ID: <1202895704.5251.23.camel@localhost> (raw)

Hi,

I'm running an Linux AMD64 guest on an AMD64 host. The host is running a
2.6.23 kernel (self compiled), the guest is running a stock
linux-image-2.6.22-3-amd64 Debian kernel.

My problem is that the clock on the guest is off (slow), while the clock
on the host seems to be OK. When doing 'time sleep 10' on the guest, it
takes about 16 'real' seconds for it to finish.

I can change the host kernel, the guest kernel or fiddle around with kvm
command line options, but I would like some guidance where to start.
Which option has the largest probability of solving my problem? Let me
know if you need some dmesg output or some other log data; I didn't want
to flood the list with random logs of both the host and the guest.

Best,
Koen
