Re: [Xen-devel] xm commands run very slow ....

Thanks Ewan.

I also saw one more discrepency which might be the root of this problem.
When I do xend start on first machine, 8 processes start up (i.e. ps aux | grep
xend shows actually 8 proceeses).
On my other machine, I see only 2 processes. Do you think it is the problem?
