Hi all,
I have a very strange situation, which I can't explain.
On a Core 2Quad server with 8GB RAM, we have 10 xen domU's, as follows:
vps.animalsaregreat.info login: root@zaxen01:[~]$ xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 512 4 r----- 232.2
actionco.vm 1 511 1 -b---- 21.8
andrew.vm 2 255 1 -b---- 52.0
animalsa.vm 3 511 1 -b---- 26.5
byracers.vm 4 511 1 -b---- 311.9
eris.vm 5 767 1 -b---- 52.5
pictures.vm 13 511 1 -b---- 21.8
pluto.vm 7 1023 1 -b---- 664.2
raftthew.vm 8 255 1 -b---- 16.8
serverza.vm 9 511 1 -b---- 247.2
zafepres.vm 10 785 1 -b---- 17.7
Some of the domU's, can't connect to the internet, even though I can
connect to them on SSH, via the internet. All default gateways are the
same, and there's no firewall setup inbetween. They simply can't ping
anything, or connect to any server, etc.
This is stranger indeed, all incoming traffic works, but no outgoing traffic.
The older domU's which was setup earlier works fine though. It's just
the 3 latest domU's which is causing a problem.
Here's the dom0's network config:

We have confirmed, the firewall on the network allows full access to,
and from all the IP's on this server so it's not a firewall issue, and
iptables has been disabled (for now) on dom0 as well as the domU's
that doesn't work properly.
