Xen users - Feb 2011 - network interrupted when booting or shutting down DomU''s on SLES11

Hi all,


I''d like to run this thing I experience by you guys.
I use SLES11SP1 which, by default, uses bridging. Whenever I shutdown or
start a DomU, all network connectivity to the Dom0 on the bridge the
DomU shares, seems to be pauzed. After several seconds I can continue
with my open ssh session, but this is kinda annoying when you have a X
client open over ssh.

Is this normal behaviour?

thx,

B.

Hello.  It sounds a lot like a MAC address assignment problem I
struggled for some time with.  Does this bug report (and resolution)
help?

Hi Bart,
which version of xen are you talking about?
I had the same issues on debian squeeze with xen 4.01 on kernel 2.6.32.5.

I didn''t get the issue again after changing values in
/etc/xen/xend-config.sxp from
(network-script ''network-bridge''
''bridge=eth0'') # my starting values
to this standard values:
(network-script ''network-bridge'')
(vif-script vif-bridge)

Maybe, this solves your issues too.

Guido

Hi Guido,

this is Xen 4.0.0. I actually created the bridges in Dom0 and my network
script is empty in xend-config.sxp, hoping this would fix things, but it
still seems to happen.

Hi,

don''t think so unfortunately: the MAC addresses are set in the config
files. I think  had the same problem with SLES10 by the way, maybe it''s
something "by design". The funny thing is that only the network on
Dom0
suffers. Other DomU''s using the same bridge seem unaffected.
