[ovirt-users] question on VM

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.
