I am interested in doing some testing with Xen. Is anyone out there using it? And more importantly, will it allow me to run other OS's inside the virtual machines? Or am I restricted to the Host OS? I want to do some work with virtual Redhat and virtual Suse boxes, but hopefully would use just one server running either Redhat or Suse as the host. Can you recommend why one host OS would be better than the other? -- Paul Buede Systems Engineer Netconn Solutions buedep@netcsc.com Office 301-739-9110 ext 2025 Cell 301-404-3941

As I mentioned in a previous message, I had just attended a seminar with Ian Pratt (xen main developer). Right now, Xen only supports Linux, FreeBSD, NetBSD, Plan9 and Solaris.

Understood, it works with those host OSes, but can I run a Suse host OS and then virtual Redhat and solaris 10 for intel machines on that? -- Paul Buede Systems Engineer Netconn Solutions buedep@netcsc.com Office 301-739-9110 ext 2025 Cell 301-404-3941

You need the Xen-enabled kernels, AFAIK. -- Jerry Feldman <gaf@blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9

Do you know of any SuSE specific resources in how to get started using Xen?

I have been playing with it and have been making a few notes. Firstly the rpms shipped with SuSE 10 have some big problems and someone on the opensuse list recommended updating to those from: http://www.suse.de/~garloff/linux/xen/RPMs-100/ Since then there has been a kernel update so some of these issues may now be fixed. So far I've only got SUSE 10 and Debian Stable running but it seems pretty stable. If you are runnign SuSE there are a few tweaks to a standard SuSE install that I have found necessary to get it running well, namely: Dissable Coldplug as this seems to increment the number of the Ethernet interface on each re-boot eth0 becomes eth1, eth2.....etc. comment the following lines in /etc/inittab: #2:2345:respawn:/sbin/mingetty tty2 #3:2345:respawn:/sbin/mingetty tty3 #4:2345:respawn:/sbin/mingetty tty4 #5:2345:respawn:/sbin/mingetty tty5 #6:2345:respawn:/sbin/mingetty tty6 This stops annoying error message on the console every few minutes. Don't use the YAST Xen install as it is broken, simply use a real disk partition or a pre-extended disk image file mounted as loopback and then use the YAST install into directory (mounted disk image file or real partition) then it will work. You will need to change /etc/fstab on the virtual machine (tip use chroot into the mounted partition) and also it's a good idea to set the root password while you are there. I have recently purchased a hosted xen virtual machine from: http://www.contextshift.co.uk/ and I'm highly delighted, it works very well indeed, so far 58 days uptime without a hitch. -- David Bottrill david@bottrill.org www.bottrill.org Registered Linux user number 330730 Internet Free World Dialup: 683864
