In the end, I it was the network bonding of the pnics. I changed from method 2 to method
5 I think. I haven't had time to read up on the methods to see which if any need
additional configuration on the switch. Changed to active/backup first and then it
started working, then changed to 5 I think active load balancing and that also worked.
The 2 load balance option sounded similar to vmware's simplest 'works on
everything' setup, which was why I tried that. Anyway, all good now
Thanks

Hi Bill,
So without firewall you can ping interfaces inside the cluster but nothing outside? Could
it be that your DHCP server is allocating internal network addresses and you need to
configure NAT?
Yours, Lior.

the firewall was stopping that. But I still can't ping outside of the
host or ping the VM from elsewhere... and the VM continues to get an IP
address from the DHCP server without issue. I have gone back to my
networks and checked them thoroughly and can't see any issues, I have
migrated the VM from one host to another and the condition persists in
that it can ping the host that it is running on and the host can ping
it (providing I turn off the firewall) numerous reboots etc and no
change. L

Hi,
I am creating my first ovirt VM from a windows 2008 R2 iso.
After setting it all up, loading the drivers etc it looks fine, but it
seems like it has no network connectivity. This is odd as it is
obtaining a DHCP address and it looks like it can browse for other
windows systems on the network. But I can't ping it, it can't ping
out and I can't remote desktop into it. Normally this sounds like a
firewall problem, but I disabled that immediately. It is using the
virtio driver. It is connected to the default network ovirtmgmt which
has a dhcp server on it. Ovirt-engine says the interface is up and
connected and windows thinks it is connected to an unknown network
with out internet access. I can't ping the default gateway from the
VM console. Seems silly, but I've kind of run out of things to try on
this now. I am using VLAN tagging on the ovirt-engine network side of
things and it is plugged into a trunked port... but I wouldn't think
that has anything to do with the VM itself as I am not doing anything
with VLANs on the VM itself, it is just connected to it. All the host
network/interfaces are pingable in the cluster as well.
Thanks if anyone has any ideas what I might be looking for.
