[CentOS] CENTOS as Guest in XEN

I'm currently using FC4 with this kernel and xen build.
http://people.redhat.com/riel/xen_for_fc4/
Works great for me (well the best so far :-)
 
I'm looking to use Centos4.2, but I have (at least)  2  problems.
1. The stock glibc causes a performance problem with tls - which I need to
use. I know many people move the tls lib out of the way - but I need it.
Glibc needs to be recompiled with a magic flag (sorry don't have it to hand
at the moment) and currently the rhel/centos kernels are broken for building
glibc. I now have a patched kernel which seems to build glibc OK.
2. There are xen patches to apply to the kernel and I don't know how easy
they are to apply to the heavily modified rh kernel? I know many people use
a vanilla kernel, but I hoped I could modifiy the rh/centos one. This is on
my list to do.
 
Regards
 
Daveh

Hi,
 
this is a great first approach for me. Do you use CentOS 4 as host os ?

Best regards
 
Niels

I use rpmstrap to do this.
 
I use this basic procedure
http://trac.samhart.net/trac/wiki/rpmstrap_CentOS4 but rather than use a
chroot dir - I create some loopback filesystems which I then mount in Xen.
 
Does that help or do you need more detail?
