Any ideas why only one DOMU will accept network connections?
I have two debian 32 bit DOMU vm''s running on a 64 bit Centos 5.4 DOM0.
Only
one DOMU network communicates at a time. Both DOMU''s use bridge
networking.
The symptoms are as follows:
1. xm create the first VM
2. It accepts connections. (e.g. ssh)
3. xm create the second VM
4. For a couple of minutes it accepts connections (ssh to either
DOMU''s)
5. The first VM stops accepting connections (ssh times out)
6. The DOM0 network drops connections (my vnc connection is lost)
7. The DOM0 connectivity returns, only the second DOMU accepts connections
dmesg is attached.
It''s 2.6.18-164.el5xen kernel on an HP DL380. DOM0 eth0 &
DOMU''s all have
static IP''s on same subnet. DOM0 eth1 is dhcp on same subnet.
