Re: Migrating VMware instances

If anyone is curious about my reasoning for wanting to do this, I have a 
number of dev systems running on VMs. Each server uses different levels of 
CPU at any given time depending on the development cycle of each group. It 
ends up being a very large pain to manage 100 or so of these VMs spread 
across 30 dual proc boxes and keep two people from butting heads with the 
cpu on a given box. OM seemed to be a pretty good answer to my issue 
allowing me to just provision everyone on the master node and have OM
deal with the cpu/memory distribution. My VMs are all linux, so I'm not 
tied to VMware if anyone knows of another project that works well with OM. 
I didn't see any interesting hints that bochs or plex86 would work, and I 
know due to kernel hooks UML is pretty much not an option.

The FAQ and vague reports from other users on the list running VMware 
under OM is what inspired me to believe it was a workable setup.
