[Xen-users] Loosing network connectivity in DomU's and crash in hypervis
Hello,
sorry I had to resend the message, mailman scrubbed my mail because of the
Mime signing.
i currently have big trouble with an Xen Setup using Scientific Linux 5 (a
clone of RHEL 5) with kernel kernel-xen-2.6.18-8.1.8.el5.x86_64 and
xen-3.0.3 .
We have an DELL PE6800 server (4 Dual Core CPU's and 16 GByte Memory) and
several FibreChannel Storages connected. The dom0 is mainly doing nothing.
The domU's are doing the hard work serving NFS and SMB (samba).
The last two weeks it run well, before we had some crashes, and today its
again starting crashing (maybe its dependent on the network load).
Most time the domU's run well but loose any network connectivity. A "xm list"
command then shows just "Device 0 not connected"
brctl show shows all the bridge interfaces, but no domU responds to the net.
In the xend.log I see a one of the DomU's crashed.
Sometimes we have a crash of the dom0 and the hypervisor. There is an screen
dump of the console appended. It looks like something in networking code.
Any Ideas what I can do?
Sincerly,
Klaus Steinberger
