[Xen-users] Debian dom0, windows domU, problems joining NT domain

[Jakub Kulesza <jakkul@xxxxxxxxx>]

Hi!

I have a problem with windows 2008 r2 (and windows 7 professional) not joining my NT domain, that is served by a linux+samba+LDAP server in the same IP subnet. 

The NT domain server works ok, windows 7 pro and windows xp physical hosts can perfectly join and log on into it. This infrastructure has been working for years now.

The XEN server dom0 is based on latest debian with xen server from the debian packages. Xen hypervisor amd64 4.0.1-5.2. This dom0 serves linux and windows domU on the local subnet with no (or minor) problems, both with HVM and paravirtualization.

The network on the dom0 is done using bridged interfaces. The dom0 is 192.168.0.132, windows domU is .142 and NT domain server is .100. The domU can use the services in the network and the Internet. The hosts in the IP subnet can use the network resources of the domU. The dom0 has all iptables general rules set as ACCEPT, the only rules added are done by xen startup scripts.

When I install a new windows 2008 r2 standard system as domU and try joining the domain from the local NT domain server I get the following error:

<pre>

The following error occurred attempting to join the domain "<my domain name goes here>":

The specified domain either does not exist or could not be contacted.

</pre>

I suspect that there is some problem with the networking. Did I miss something? Can you recommend looking into some obvious setting somewhere? I've tried looking for similar problems on the net with no result, so I suspect that I've messed up something basic.

The configuration for the windows domU is the following:

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

builder='hvm'

memory = 1024

shadow_memory = 24

name = "win2008eval1"

vif = [ 'type=ioemu, bridge=eth4' ]

acpi = 1

apic = 1

pae = 1 

disk = [ 'phy:/dev/vg/win2008eval1,hda,w']

vcpus = 1

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

boot="c"

sdl=0

vnc=1

vncconsole=1

vncpasswd='kuleczka'

serial='pty'

usbdevice='tablet'
