/rem
I've been toying with Xen Virtualization.
I've got two Fedora Core 5 boxes now running it.
So far I've been putting FC5 in the Xen Clients,
but I'm interested in being able to do other distros.

Just from reading web pages:
/list(
* http://mark.foster.cc/wiki/index.php/Centos-4_on_Xen got me started
* http://hackers.progeny.com/~sam/rpmstrap/releases/
    RpmStrap bootstraps several different distros
    into Xen clients:
/tt centos3     centos4     heidelberg  mandriva10  pdk         sl304       sl402       stentz      tettnang    yellowdog4
* "pdk" is a Debian Sarge based distro-maker:
http://componentizedlinux.org/index.php/Downloads
* CentOS is repackaged RHEL

/section Benchmarking
I'm using "
/tt untar; configure; make
" on gcc-4.1.0 for benchmarking machines:

| real | user | sys | Xen Mode | Processor
| 36m1 | 30m8 | 5m2 | non-Xen | /tt AMD Athlon(tm) 64 Processor 3200+ (2200MHz, 5502bogomips)  2.6.16-1.2096_FC5
| 46m25 | 31m1 | 11m44 | xen0 (Xen Host) | same
| 44m51 | 30m24 | 11m12 | xenU (Xen Client)| same
| 82m59 | 52m40 | 22m16 | xen0 | /tt AMD Athlon(tm) XP 2200+ (1792MHz, 4483bogomips)
