Xen 3.x and SBCL (or other lisps)?

Hello all,

As many of you surely know, we (The Tech Co-op) host quite a few lisp
related web sites and application on our Xen VPS service. We've been
using Xen 2 in 32-bit mode exclusively, even though Xen 3 has been out
for quite a while, as we had troubles with SBCL crashing Xen 3 on our
configuration (you may remember common-lisp.net having a week of daily
oopses).

I've heard reports of similar problems with other VPS hosts (if fact a
number of our current members came to us this way), but recent Xen
releases seem to have solved the problem (on my test machine anyways),
an i'd very much like to upgrade.

So, comp.lang.lisp, have any of you had recent experience with Xen 3 and
SBCL that you'd like to share? Specifically 64bit on the AMD
platform? Reports on other lisps would be nice to hear about as well.
Also, any experiences with some of the other virtualization packages
(openvz etc)?

And, while i've got you here, is there anything you'd like in a lisp
related hosting organization that is either not currently provided by
anyone, or could be made better by us?

Cheers,

drewc

Strange timing 8-O

I had major problems frying up my customers Xen instances by trying to
compile SBCL lately. But wile investigating the problems I realized that
our main SBCL webserver was running on a Xen instance as well - for
several month without any problem. The only difference: the crashing Xen
servers all run Xen 3.0.n whith n < 2 ...
So it seems that a Xen update is all thats needed (unfortunately hard to
do on some of our boxes ...).
