Seems FreeBSD now works with Xen; at least as DomU under FreeBSD 8.0…

That’s a real nice way to blog a topic like this. I don’t even have to google your points because you’ve already done it and posted the links inside your post. Rock on.

I’ve been attempting to get this working for a week, except on an Ubuntu host (dom0). From what I can tell, recompiling the Ubuntu host to run a non-PAE hypervisor and kernel crashes the system (I.E. it complains something about running a non-PAE kernel on a PAE hypervisor, even though I made sure that both are non-PAE, etc.) I’ve also tried to recompile the 7.0-BETA2 FreeBSD kernel to have all the XEN and PAE options enabled, but the stock GENERIC kernel doesn’t have the XEN extensions and the Kip kernel source that I’ve downloaded throws hundreds of compiler errors. So, from what I can tell, there is no way to get a PAE XEN kernel under FreeBSD 7.0 (at least BETA2). Also, when I’ve gotten around the actual compiler errors, I ran across a line that said “PAE under XEN not supported.”, and actually stopped the compilation. So, I would think that using VMware server (which is where I went as well, after attempting Qemu, which I thought would be less CPU intensive, would be a better choice… it crashed too often and doesn’t have very good networking support) is the only viable alternative. I really like the Xen methodology, but its pretty useless if its not supported ubiquitously.

Good writeup, and nice to know CentOS-5 can do xen-dom0 out of the box.
Too bad PAE gets in the way like that. They should make PAE-enabled domU kernel available or the default. VMware server does a pretty good job of running FreeBSD, another option is jail or qemu.

Ultimately, I gave up on Xen, and used vmware server.

I’ve yet to contact the developers, the general consensus I got from their sites, etc, is that development on this has stopped.

I feel the Xen open source community is very disconnected.

I’ve been investigating this as well and have run into the same problem. Have you already contacted the developers you mentioned?

I wish i386 and amd64 FreeBSD Xen 3.1 domUs would be here soon. =)
