Parallels Virtuozzo, but the installs on there are the corrupt one, and the fresh install.. I currently have them powered off until I can figure out the best course of action to restore the corrupt data.
The memory is "dedicated", 1GB soft limit, 1.5GB hard limit. it only uses 5-600MB when running normally.
So users can still operate I have the backup copy running on a different VM server (VMware Server).
