Xen network failing



I've been trying to get xen working on fc5t2 + rawhide and I just can't
get the networking working.

* Here's what I've got installed:
kernel-xen-guest-devel-2.6.15-1.43_FC5
xen-3.0-0.20060130.fc5.6
kernel-xen-hypervisor-devel-2.6.15-1.43_FC5
kernel-xen-hypervisor-devel-2.6.15-1.40_FC5
kernel-xen-guest-devel-2.6.15-1.40_FC5
kernel-xen-hypervisor-2.6.15-1.40_FC5
kernel-xen-guest-2.6.15-1.43_FC5
kernel-xen-guest-2.6.15-1.40_FC5
kernel-xen-hypervisor-2.6.15-1.43_FC5

* I'm booting the 2.6.15-1.43_FC5 hypervisor.

* I scale the memory in Domain-0 down to 128M via
xm mem-set Domain-0 128
(the machine has 512M total)

* I run the newest xenguest-install.py from people.redhat.com.  The
memory is set to 256M, w/a 4G disk image.  I'm pointing to a local ftp
mirror of rawhide.

* Installation starts and it asks for language & keyboard.

* I let DHCP config the interface.

* A quick window flashes (I can't read it -- its too fast), but about 3
or 4 minutes later I get a 'failed to connect to FTP server' message.

* the firewall is turned off, but when the domU is running, there is a
rule:

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere            PHYSDEV
match --physdev-in vif2.0

* ip forwarding is turned on (echo 1 > /proc/sys/net/ipv4/ip_forward)

* ifconfig -a looks like this:

* brctl show displays this:
bridge name     bridge id               STP enabled     interfaces

                                                        vif2.0

* the eth0 interface on Dom0 is dhcp generated, if that makes any
difference.

Any clues on what I'm missing?  I'd guess that my ip for the Dom0 is on
the wrong interface, but I'm not sure which one, or if that's even
right.

Thanks!
