[Xen-users] Xen, LDAP and Berkeley DB

[jsiepkes@xxxxxxxxx]

Hi!

I'm currently in the process of evaluating Xen. I've made a test setup
with Debian Sarge as dom0 and a couple of domu's also with debian sarge.
The purpose of the setup is server consolidation, which Xen does a great
job with from what I've read (And experienced so far :) ). 

One of the things I would like to run in a domU is an LDAP server.
However it has come to my attention that there are some troubles with
BDB, OpenLDAP and Xen. Some people are advising against using an LDAP
server in an Xen domu
(http://www.openldap.org/lists/openldap-software/200603/msg00216.html). 

I've installed OpenLDAP in a domU and ran SLAMD against it to check its
performance. The performance seems OK at first sight.

>From what I understand Xen's inability to support Native POSIX Threading
is the root cause for the problems with programs like BDB, OpenLDAP and
Fedora Directory Server. Is there anybody who can shed some more light
on this for me ? Or beter, somebody who runs a live LDAP server inside a
domU ?

Thanks in advance,

Jasper Siepkes
