Hi
I'm losing the network connection on both the Dom0 and the DomU's,
fx SSH is randomly losing the connection and nfs time-out for 30-60
seconds periods.
I've tried "ethtool -K ethN (rx off| sx off| sg off| tso off)" as
similar threads suggest to correct connection loss, but nothing.
Dom0 is based on Debian Etch Amd64 (AMD Athlon64 X2 3800+, 1GB RAM),
kernel 2.6.18-4, Xen-3.1.0 x86_64. The DomU's is also Debian Etch
Amd64 (lvm), based on the same kernel and i got a Windows 2003 (hvm)
host. The DomU's has fixed IP and MAC-address (00:16:3E:00:xx:xx).
The reason I use the binaries instead of the Debian packages is that
couldn't get Windows 2003 working. It works flawless on 3.1, but
instead it brought the network problem.
Dom0 has 2 NIC's. Eth0 is 172.16.0.2/27 and lanbr, and eth1 is
dmzbr. Unfortunately I never manageded to put the entire
configuration into "interfaces". But in the end it should give the
same result.
I turned debug on in Xen. And this is the part of the xend.log
either during or right after I lost the ssh connection to Dom0 and
to one of the DomU's, but not the one mentioned in the log.
