Xen users - Jun 2008 - OS decision for dom0

Hi,

I have my applications running on Debian, but I have read up on Xen and
learnt that NetBSD-dom0 has the best performance.  Could someon suggest the
best OS for Xen dom0?

Thanks for your suggestion.

Pete

Hi everyone,

I would really like to have an answer to that too, since I''m just  
about ready to set up my new system. Since thiss my first try at Xen  
and I don''t want to have to reinstall the dom0 for quiet a while at  
least, it would help me very much if someone could share his  
knowledge on that one.

Basic requirements for me are:
- - Good performance on bridges and hdds/images
- - Low memory usage
- - PCI passthrough (with performance as high as possible)
- - Possibility of not letting the OS take the primary VGA (and use a  
serial port instead)

I basically want to use the dom0 as a link to Xen only, it does not  
have to do anything but manage the VMs and the stuff they need. The  
systems I have considered until now are Ubuntu Server/Debian (because  
I know these system very well and they could use the repository  
cache), a minimal Gentoo (because of the possible optimization) and  
CentOS (because for whatever reason it seems to be very popular with  
Xen users). Any thoughts on which one would do best? Or is there  
another system that will do better?

Thanks,


Paul.

I certainly haven''t compared every possible version, but I
recently switched from SLES10sp1 and the Xen that ships with
it to debian etch and building Xen 3.2 manually from the mercurial
repo, and the system has been lots more stable since
then. The VMs tend to stay up all the time instead of crashing
randomly :-).

See http://lists.xensource.com/archives/html/xen-users/2008-02/msg00101.html
for my experience with packages I needed to add to get Xen
to build from source on debian.
