Re: RHEL VM on Xen

[Joseph Mesterhazy <jmesterh iastate edu>]

This is actually something I have been working on this week, so I  
made a quick tarball of my scripts. The Anaconda in RHEL does not  
work under Xen, so this uses the older method of creating a disk  
image, and bootstrapping RPMs using yum and package groups.

You can download an archive of my scripts at http:// 
powermacg5.ece.iastate.edu/~jmesterh/xen/build.tgz

Quick instructions:

There are two scripts here, buildrepo.sh and makeimage.sh.  
Buildrepo.sh will take the RHEL iso images (place them in the iso's  
folder) and create a Yum repository from them. You will need to  
install the 'createrepo' RPM also, and also change the configs/ 
yum.conf to point to the path of this new yum repo.

Makeimage.sh will then build an 8GB RHEL image using this yum  
repository, setup networking and install some additional packages  
(apache and mysql).

One odd thing I have noticed is that some of the post-install scripts  
in the 'core' package group get executed locally on the FC5 machine,  
and manage to break booting additional guests until you reboot.  
Because of this I build my disk images on another FC5 box, and then  
copy them over to the Xen server when they are ready. If you do this,  
make sure your build host has the Xen kernel RPMS installed.

These scripts weren't really written for distribution, so if they  
break your system you get to keep the pieces :)
