I need to build a LAMP server using UML. Apache and PHP5 work fine, but 
MySQL don't.

I've just found a similar problem here:

But it seems to apply only to x86_64, not my case.

Here are some information:

host # uname -a
Linux loghost1 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux

host # linux --version
2.6.18

guest # uname -a
Linux neo 2.6.18 #2 Wed Oct 4 19:34:37 CEST 2006 i686 GNU/Linux


guest # tail /var/log/syslog | grep mysqld

What can be done?
