Adil, I have replied only to the -user list, as this is the appropriate forum for such questions.

What sort of "slow"? i.e. is it CPU bound or I/O bound. What is the load average of the host? Yes, there is a limit, but it depends entirely on what you are doing with the UML guests. Typically the thing that does not scale well is the I/O performance. UML guests place a higher load on the I/O sub-system than running natively would. Mulitply this by four, and you can easily exceed the ability of your host to shift data on and off the disk. > Im giving each UML memorey to 32 m and my host is not SKAS patch. You'll certainly want the SKAS patch if you are at all concerned about performance. At 32MB, I would suggest that the UMLs will run into swap fairly quickly (which will murder performance) but you don't appear to have swap configured.
