Older (2006-05) Fedora Notes Follow *****

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:

• 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: 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

Xen Hints (Fedora Core 5, FC5)

• chkconfig --list | grep xen ===> xend, xendomains
• rpm -qa | grep xen ===> kernel-xen0, kernel-xenU, xen
• xm { --help | list | mem-set 1 300 | create -c myCleint | console 1 | reboot 1 }

Benchmarking

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