You are right, I can't resolve names from inside a DomU. I tried doing
"apt-get update" and it was unable to connect because it couldn't
resolve names. In the Dom0 it does work though. How do I fix that? I
never run into such issue before. Do I need to install dnsutils? I
cannot use nslookup in a DomU as it is not installed.

Here is the /etc/resolv.conf in Dom0:
----------------------------------------------------
nameserver 127.0.0.1
nameserver my.server.IP.address
nameserver 213.186.33.99

Here is the /etc/resolv.conf in a DomU:
--------------------------------------------------------
nameserver 213.186.33.99

Is 213.186.33.99 the IP address of Ovh DNS server?


Beside that when I ssh I use the IP address of the DomU, so I use the
following command: "ssh user@xxxxxxxx" therefore DNS is not part of
the equation. Am I right?

There is only stuff about cron, nothing special I could find.

Yeah really strange. It might be Xen's default behaviour, there is
probably a special command to give back the freed memory to Dom0.
