I would run tcpdump somewhere on the LAN ( it's broadcast request) to check
UDP checksums propagated via Dom0 Ethernet interface.

By the way,
I noticed that, after few minutes, the system goes ahead and
finish the boot process, but I can't still understand why there
are a lot of problems with dhcp.
Actually, if I perform such a "ifconfig eth0 up && dhcpcd eth0"
eth0 obtain an IP address without any problem.

I also tried the same identical filesystem image on a debian-lenny
host system (XEN of course), and I get the same problem as regar DHCP, but, if I
let the guest machine to continue the boot process, I get many
other problems like:

This is making me crazy.
