Ovirt devel - Aug 2009 - iSCSI questions and VM Creation questions

Hi,
I finally managed to have one node working.
I added a iSCSI LUN (ok if selinux is set to 0) and wanted to create my first
VM.
So I created a VM and had some issues:	
*	I can choose boot from HD but I'm just able to choose the LUN, not a
specific size in the LUN like you can do in vmware ESX. So, do I have to create
a LUN per VM? If yes, it's quite complicated...
*	If I choose boot from HD, there's no way to specify another boot parameter
(I would like to use a liveCD to install a distro). Is it possible to do that?
*	I've three networks (the VM created are supposed to act like routers), one
management/guest/storage and two others. When I boot, all these interfaces are
put on the same bridge (I've got 5 ethernet interfaces) instead of being put
in three different bridges. Is it normal? FYI, I've created a bug
(https://bugzilla.redhat.com/show_bug.cgi?id=515684) because the igb kernel
module (needed  for some Intel Ethernet cards) wasn't working. Now it works
(changed a little bit blacklist.ks) but I have to manually modprobe at the end
of the boot so perhaps that's why only one bridge is created?

Thanks in advance,

Good. For what it's worth, there is now an updated selinux policy for
libvirt, should allow you to leave selinux turned on.

We had intended people to create LVM partitions on top of an iSCSI LUN,
so you have some flexibility on the size and allocation of your VM
partitions. You should be able to do this from the UI.

Hmm, I think what you want to do here is create an ISO image profile in
Cobbler for your liveCD and boot from that to install. You will just
need to put your ISO in a shared storage volume that the nodes can
mount; cobbler will supply the node with the path to the ISO on shared
storage, and it will then boot the VM from there.

Hmm... we have been having some issues with network config. The bridging
of the interfaces depends on how you have the host networking set up
("edit networks" dialog from the Host details pane). I'd love it
if you
would try again with the release we are building today (some new network
config UI and code) and let us know if it works -- if not, detailed info
on how the NICs are supposed to be configured vs. what is actually
happening would be really helpful.

Thanks,
