[Xen-users] xen-3.2.0 problems with time (and space)

[Massimo Mongardini <massimo.mongardini@xxxxxxxxx>]

Hi,
   I am experiencing some issues keeping my clock in sync in a series 
of domU with xen-3.2.0.
every node is set to ntpd sync to a central server.
(server-0034 is a bare metal server and is in sync with the rest of the 
world, while 35-41 are rhel4 domUs)
--------- server-0034---------
Fri Jun 20 11:49:48 GMT 2008
--------- server-0035---------
Fri Jun 20 11:50:54 GMT 2008
--------- server-0036---------
Fri Jun 20 11:49:52 GMT 2008
--------- server-0037---------
Fri Jun 20 11:49:50 GMT 2008
--------- server-0038---------
Fri Jun 20 11:49:50 GMT 2008
--------- server-0039---------
Fri Jun 20 11:50:50 GMT 2008
--------- server-0040---------
Fri Jun 20 11:50:42 GMT 2008
--------- server-0041---------
Fri Jun 20 11:49:51 GMT 2008

on the logs I see many:
Jun 20 11:54:55 server-0041 ntpd[2573]: frequency error -512 PPM exceeds 
tolerance 500 PPM
Maybe as a side effect to this, the domUs timeout the connection to a 
nfs server from time to time
Jun 20 09:15:38 server-0036 kernel: nfs: server fs-cluster not 
responding, still trying
Jun 20 09:15:52 server-0036 kernel: nfs: server fs-cluster OK
Jun 20 09:16:35 server-0036 kernel: nfs: server fs-cluster not 
responding, still trying
Jun 20 09:16:35 server-0036 kernel: nfs: server fs-cluster OK

details:
dom0: rhel4
xen: 3.2.0 compiled sources
domU: rhel4

I also have another xen environment that I use for tests with xen 3.1 on 
a rhel4 dom0 and it doesn't seem to suffer for this issue:
--------- server-0002---------
Fri Jun 20 12:29:05 GMT 2008
--------- server-0012---------
Fri Jun 20 12:29:05 GMT 2008
--------- server-0040---------
Fri Jun 20 12:29:05 GMT 2008

any tip?

cheers,
Massimo
