I have sucesfully run debian kfreebsd and freebsd as paravaritualized Xen Guest. Networking is working corectly. Still it is quite unstable to be usefull. I can have big uptime, but under a stress there are many crashes. take look at: http://smp.if.uj.edu.pl/~baryluk/kfreebsd-xen/ -- Witold Baryluk JID: witold.baryluk // jabster.pl signature.asc Description: Digital signature
RE: Running FreeBSD as a guest under xen
Hi Andras, Thank you for the prompt response. I have managed to install both 32b and 64b VMs in HVM mode but I am lacking to the knowledge and understand to compile the XEN and XENHVM kernels. Is this something you can tell me how to do? Are both XEN and XENHVM paravirtualised kernels or are there other options for FreeBSD 8.0? If I got answers to these questions I will try this very soon.

Install, reboot and that's it, the next steps are for automating and other features.

Thanks for the response. Pass a message my way on this list as soon as your tests are complete! I'd like to know as well for similar reasons.
