I have a Dell PowerEdge 1950 with two NICs Broadcom NetXtreme II BCM5708
1000Base-T. I installed CentOS 5.1 and Xen 3.0.3 (RPM). One of my
virtual machines has Windows 2003 Server. In this virtual machine my
NICs appears like "Realtek RTL8139 Family PCI Fast Ethernet NIC". The
problem is that when I ping to other machines sometimes the reply time
value is very high:
C:> ping 10.1.1.1

It important to indicate that the "real" time is good ( approximately
between 1 and 2 seconds ). The problem is some applications used this
value to monitor some servers and send alarms when time value is high.
How you can see some time the reply value is negative.
The problem is only with virtual Windows machine.
What can I do? Some idea?
Sounds like you have a clock problem to me.
Have you tried disabling acpi in the VM definition?
There's also something called timer_mode, but good luck finding any
documentation about it (like a lot of other Xen stuff).
