Hi, Thanks.. I've got it working now your reply and blaisorblade's helped me fix it. The network problem that I was talking about is also fixed now. Debian puts the uml_net in /usr/lib/uml/ which is not in the path. Therefor the UML kernel can't find and execute it. Now I can continue to e

I seams to work now. I disabled TT mode (which is broken and crashes on my server) and did a static compile (skas0 only). Right now in this moment I run 4 Uml`s with a complete ram usage in sum of 1,5GB. The biggest one has 500MB. Currently I`m setting up even more guests. I disabled everything i

I though, that disabling HIGHMEM and running <256MB ram guests helped. But that was yesterday. Today I had to 20x start/kill the guest before he went up (2.6.15-rc7 skas0). But YES, you can call it a "better result" because I didn`t give up until it started :-) I don`t understand it at all :-/
