Ok, I'm using 256MB, this means, I should try to set ulimit -l to 256MB.
Nevertheless, I'm wondering that I don't get the same problem with root.
Obviously, the limit is ignored as root.

Hmm, should work like this (I'm already running VM's this way, but
without changes to ulimit):

Define a new user and run libvirt with this user. For this user context,
ulimit can be set to, lets say, 256MB.
I'll try it.


Thanks for your explanations,
Andreas
