I hoped to avoid doing something I do only every few years ;-) I'm quite familiar with using Wireshark/Etheral on Windows, but I used tcpdump only once or so, ever. I remember I can use tcpdump logs with Wireshark, can't I? Anyway, I just installed xen 3.2 and VMs are well. It didn't solve the DHCP problem, so I will check tcpdump soon. But I found a problem with python when I wanted to add a DomU to the xen managed domains. It seems the xmlproc library is missing. I tried to install python-xml (as is recommended for Debian) but there is none for CentOS. libxml2-python is already installed and the only other module with xml in the name is python-lxml which doesn't look like the one I need.
