As it turns out this was a "pilot error"... issues with internal routing. Things are working OK now.
Sorry about the noise.

Hello everyone,
I grabbed xen-3.3.1 sources from the Mercurial repository (xen-3.3-testing.hg, changeset 475:1cf755387728, from Oct. 23, 2008) and built Xen from these sources on a 32-core (8 quad core Barcelona CPUs) SunFire machine, running an Ubuntu 8.04 (Hardyy Heron) distribution. Everything seemed to be going OK until I booted an HVM (also Ubuntu 8.04) domain. That domain boots normally but it is unable to go over the network (and I cannot reach it over the network either). My configuration file is as follows:
import os, re arch = os.uname()[4] if re.search('64', arch): arch_libdir = 'lib64' else: arch_libdir = 'lib'
def vmid_check(var, val): val = int(val)
if val <= 0: raise ValueError return val
# Define the 'vmid' variable so that 'xm create' knows about it. xm_vars.var('vmid', use="Virtual machine id. Integer greater than 0.", check=vmid_check)
# Check the defined variables have valid values.. xm_vars.check()
builder='hvm' kernel = "/usr/lib/xen/boot/hvmloader" memory = 256 shadow_memory = 8 name = "tdf_%d" % vmid
vif = ['type=ioemu, bridge=eth0'] disk = ['file:/mnt/sdb1/vm_diskimgs/hda%d.img,ioemu:hda,w'%vmid] cdrom="/root/ubuntu-8.04-server-amd64.iso" device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
boot = 'c' sdl = 0 extra = 'console=xvc0' serial='pty'
The bridge on dom0 seems normal to me (/etc/xen/scripts/network-bridge status):

Does anyone know what may be gogin on? I have searched for the past couple of days. but I have not seen anyone else with a problem like this one.
Any help would be greatly appreciated.
