Honestly, it is just from a lack of understanding of what is happening when it does break (as it is for us when doing a hypervisor install on a fresh box). Normally, I can just dig through the stack and figure out what is happening. There are enough areas where I don't have some foundations that I'm not able to do so here (yet).

For example, I don't quite understand iSCSI, Multipath, etc enough to know what is breaking, and why.

I'm accustomed to being able to dig deeper at each level until I can generally see what is breaking.

This confusion will go away as I get a bit more experience and have a "map" of what is going on on this level.

FWIW, I started reading the Libvirt book previously mentioned and it's pretty straight forward. It looks like I just need to get through this enough to get a good foothold so that I can figure out how to either fix things when they break or point out properly why something is breaking (so I can get the appropriate help).

Actually, yes :)  In:
1. Learn libvirt more (in progress)

2. Review source for vdsm-tool to have a better sense what is going on
3. Setup an iSCSI system so  that I can make luns, build a system, play with storage pools this way
