Hi Folks,
I've got oVirt 3.0 installed on a Fedora 16 machine, and I'm planning my
data center. Great process, by the way, very straight forward. I'll have two
host machines (on order) which I'll likely load with the oVirt image. These
two hosts each will have a large amount of RAID 5 local storage. Here's my
questions..
Storage: If I'm using this local storage on each host, will I be able to
migrate VM's from host A to host B if needed, or does storage need to be
shared. I guess another way of asking the question is, what's the best way
for me to set this up? :)
Networking: When I set up a logical network, how is that accessed from
the physical network? For example, if my physical network is 192.168.1.0,
and my logical network is 155.223.44.0, how will I connect to port 80 on a
virtual machine with the IP 155.223.44.5 from IP 192.168.1.10. Is there port
forwarding? I didn't see mention of it in the guide.
Thanks very much!

You'll need shared storage - NFS, iSCSI or Fiber channel. In the future they'll be
other options such as native Gluster, but for now you'll need something like NFS.
Networking: When I set up a logical network, how is that accessed
from the physical network? For example, if my physical network is
192.168.1.0, and my logical network is 155.223.44.0, how will I

Thanks for the Reply, Andrew. OK, so local storage obviously isn't the
best architecture, but that's what I've got, so I'll figure something out.
How about the networking question? How are people getting to their VM's
from the physical network? Here's the original question..

What you seem to be getting at is a feature like VMware, VirtualBox, or the libvirt
default constructed virbr0 interface to provide NAT to your guests. At the moment
RHEV/oVirt only supports bridged networking with the ability to vlan if you so wish. In
essence all the typical functionality of the linux bridgeutils and bonding driver. The
restriction at the moment is that RHEV/oVirt only allows creating a valid network from a
bridge which is attached to physical NIC. I have the usual suspect tricks by creating
virtual NICs, using openvswitch, or VDE, etc in an attempt to achive both the notion of a
private internal network between guests or a NAT networking for the guests.
Thus this limits the ways you could achive NAT or internal networking for your guests.
- Bridge to a physical NIC(s) which are attached to a network which already NAT'd.
- Bridge to physical NIC on a private switch and create mutiple vlan's on top of that
- Via the vlans you can in essence create multiple networks for your guests
- Via the vlans you can either NAT to multiple networks or create private internal
networks for your guests
--> attach a VM or linux box with one nic attached to the private switch vlan this NIC
appropriately and go to town with NAT attached to an external network on the other NIC
- Hand configure macvtap (VEPA) or create vdsm hook for it and bridge to a private switch
which supports hair-pinning (guest to guest communication)
Suffice to say this is definately an area that both RHEV/oVirt could improve.

Hi Chris,
Thanks very much for taking the time to write such a detailed reply.
That answers my question, and that's what I'd suspected since I didn't see
any reference in the docs.
Best regards,
