Try booting with a static IP configuration.  For dhcp you will need to
build your own xenU kernel since the one we provide doesn't have dhcp
client support compiled in.  Alternatively you could use our xen0 kernel
which has dhcp client support compiled in.

Unless you're exporting a block device to the domain as hda5, this will
fail when swap gets enabled.  Also, your entry for the root fs is not
correct.  The 1st field should be of the form server:/path/to/root -- 
I usually use IP addresses, a hostname might work, certainly if it's
defined in /etc/hosts.  The filesystem type needs to be nfs, not ext3.
Also the dump frequency and fsck pass number fields should both be 0.
