Well, I must say that creating vhost for me it's too advanced a feat to take it.

On the bright side, I just managed to get my vBulletin to work. I completly uninstalled Litespeed, manually removed all files left behind (mainly php files), then I installed it again, choose to have php from the start, compiled PHP (5.2.17, the same as with apache), but I left out this:

--with-mysqli=shared,/usr/bin/mysql_config

Probably this wrong mysqli configuration caused vBulletin not to start (I just had blank screen). Now it started, but I need to setup xcache (need to see where the xcache.so is).

I need Plesk, as I use it for protecting directories and other things. I need to have it running with Litespeed.

The biggest problem was not enabling PHP from the very start. You probably should stress it out, I thought that I would be able to compile PHP later, but it didn't went well enough.
