I guess it has something to do with the ballooning driver for Dom0. It looks like I just tried to allocation too much memory to DomU and the

went down hard. I think there's a setting in xen to the min amount of memory to go down to, but I'm not sure why Dom0 is using 600mb of RAM.
Is
there a mini installation of CentOS that I can do that would use less
RAM?
I've already unchecked all the boxes when installing CentOS. I would
like
Dom0 to be as small as possible, both due to RAM usage and from a
security
perspective.
I've not familiarized myself with xen yet, but have you considered VMware Server? I haven't had any serious problems with it, and none at all since v1.0.5 came out (1.0.6 is the current one). Works nicely, stays within its memory allocation, and top et al work as you'd expect them to.

I evaluated VMware Server myself (v1.0.3) and at that time, Disk I/O was pretty bad within a virtual machine. The only solution I found was XEN with paravirtualization. Has there been any progress on that with later releases?
For example:
dd if=/dev/md5 of=/dev/null bs=1M count=1000 on bare metal gave 272 MB/s same within VMware gave only 47,9 MB/s
I know that dd is not a benchmark - but for measuring sequential reads within a system its fair enough for me.

Does anyone has tested Openvz? I see many hosting providers using Openvz with CentOS, but haven't had the time to tried out yet, I know it's not paravirtualization but maybe someone has been able to use it sucessfully? I have the same issue with RHEL 5.2, just showing 4Gigs of my 6Gigs box.
