[Xen-users] Help get Xen 4.1 running

[Bud Bundy <budric@xxxxxxxxx>]

Hi,
I'm trying to get Xen 4.1 running on Ubuntu Server 11.10 Dom0.  
I installed the following: apt-get install xen-hypervisor-4.1-amd64 xen-utils-4.1 xenwatch xen-tools xen-utils-common xenstore-utils

Xen grub kernel starts, and xend is running.

In xend-config.sxp (vif-script vif-bridge) is uncommented while (network-script 'network-bridge') is not.  I used http://wiki.xensource.com/xenwiki/HostConfiguration/Networking to configure xenbr0.  Here's sample brctl output taken after a domU started:

bridge name     bridge id               STP enabled     interfaces

virbr0          8000.000000000000       yes

xenbr0          8000.00219ba1a024       no              eth0

                                                        tap4.0

                                                        vif4.0

Then I created LVM volume called "ubuntu" (didn't call mkfs on it) and created .cfg file:

kernel = "/usr/lib/xen-default/boot/hvmloader"

builder='hvm'

memory = 512

shadow_memory = 8

vcpus = 1

name = "ubuntu"

vif = [ 'type=ioemu, bridge=xenbr0' ]

disk = [ 'phy:/dev/storage/ubuntu,ioemu:hda,w', 'file:/mnt/iso/ubuntu-11.10-server-amd64.iso,ioemu:hdc:cdrom,r' ]

device_model = '/usr/lib/xen-default/bin/qemu-dm'

boot="dc"

sdl=0

vnc=1

vnclisten="0.0.0.0"

vncconsole=1

vncpasswd=''

stdvga=0

The ubuntu installation ISO boots and I can VNC into the installation.  First the installation throws an error "error while running modprobe -v xenbus_probe_frontend" during the search for cdrom step.  Then installation detects no networks - even though you can see the bridge is there along with some interfaces like vif4.0.  Finally there are no hard disks detected!  

Thanks for any help.

Below are the log files.  There are a few errors in the logs, but I couldn't google how to fix them.
