FreeBSD stable? was Re: Xen FreeBSD port is available?
I've had a VM up and running for about an hour and 45 minutes running
the lmbench3 OS benchmarks. The results aren't going to be that
interesting as I have a lot of diagnostic code in the kernel. However,
it does serve as a first order sanity check of stability.

What all do you need to do beta testing? I have a loopback image (file)
that I use that can probably be compressed down to 100MB. The i386-xeno
tree more or less (one needs to add a few symlinks) just drops into a
FreeBSD 5.2.1 tree.

How stable do you need it to be? There is a known issue that I'm working
around by disabling pre-faulting on a 64MB range of the VA.

If you're inclined to work on it as well I'll send you a patch with the
added debugging support I've added to xen. It has proven *extremely*
useful.

Great.

Does your loopback file contain a normal userland or is it modified in
some way? If it is normal, we should be able to build one ourselves
without any problems.

Regarding the source we will of course need whatever is not already in
the cvsuppable source.

At this point just stable enough to get a good feel about how it will
run. We don't have any immediate plans for production.

Please do.

What Xen tree/changeset are you using? This was done against 1.1354 on
unstable. I pulled 1.1450 and discovered that the domain builder API has
changed, so I might as well take the time required to change the init
path so that freebsd can be booted by the unified domain builder.

Hi Kip,

Would you tell me where I can get your source?
I'd like to try it, thanks. I'm using Xen 2.0 source.
