Thanks Avi,
Technically: yes. However, we strongly recommend you don't. However, if you absolutely really want to, I recommend using NFS instead of iSCSI to share the unused space.
Curious question: Why do you recommend this instead of iSCSI?
Our testing shows that NFS is less likely to cause CPU starvation of the guests.

Hardly exotic, it's from EPEL. :) Though, there is one that ships with OL6 in the iscsi-initiator-utils package.
Also, with OVM 3.3, the unused local space can now be used as a storage repository for local VMs.
Yes. But it is on ocfs2.. and local. So no fail-over, and backup/mirroring for cold stand-by is all very clunky, it seems.
Well, you can't use an exported local file system (either via iSCSI or NFS) for any of that either. The only way you get failover is via shared storage.
Again, ensure you're running Oracle VM 3.3 which uses MySQL Enterprise by default. It's also a lot faster.
Yes, I have this, and noticed that it did not like my local MySQL install.
Correct. It assumes it's the only MySQL instance on the box.
However, the initial startup of WebLogic can be pretty long as it runs all the discovery scripts to find and enumerate active OVM servers.
I think I should only start it when needed, as long as I have it on the local desktop.
This is fine. You don't need Oracle VM Manager running all the time. Only when you need to make change to the pool.
The exercise I am going through, satisfying proprietary software, is exactly a demonstration to show the benefits of open software because the later gives you the freedom of choice:-)
Oracle VM Server is Open Source. :) It's just Xen with some fancy tooling. You can shove libvirtd on it and manage it with most Xen-aware management tools, but obviously it won't do all the nifty OVM stuff that comes with the Manager. Have fun with your project though. I went through a similar exercise a few years ago. Cheers, Avi
