Re: [Xen-users] install other OS to unprivileged domain

Hello,

# cd /tmp && wget http://fv.kh3.org/tmp/dpkg-1.13.11-2.src.rpm
# yum install autoconf compat-gcc-32 gcc gettext-devel automake
# rpbuild --rebuild dpkg-1.13.11-2.src.rpm
# rpm -ivh dpkg-1.13.11-2.src.rpm
   1:dpkg                   ###########################################
[100%]

work well on my Base FC4 system freshly installed ....

Let me know error messages....

For your kernel problem, few month agos, Gino Ledesma sent me his spec
for xen stable release on CentOS.
I adapted it for FC4.
Actualy we use it on a production server and it seem to work well....
Have a look at it and send me some feedback....
The srpm will be downloadable soon....
