I have Xen 3.0.3 installed on RH EL5 via RedHat RPMs. I have a Win/XP Pro HVM and a Linux rh5 HVM. I can create both w/o a problem and can interact with the VNC based console for both VMs. The Linux VM interacts via DHCP, obtains an IP and seems to work fine on the network. The Win/XP VM doesn''t work with either DHCP or a static IP address assignment. I can see the virtual interfaces with ''brctl show'' and don''t recognize a difference. The hardware devices dialog on WinXP shows the network in the green. What am I missing here?

Thanks for the followup ... the domUs were initially created using virt-manager
which gave me workable config files for this Xen version. I then tweaked the
files as needed and use xm to manipulate the VMs.
It appears the Xen is emulating a RealTek ethernet adapter, so I downloaded the
latest drivers for the 8139 device and created an iso which you will note as the
current CD. Unfortunately, windows couldn''t correlate any of the
devices in the cd image with its view of the adapter. I forced the install and
the adapter didn''t come up. I reverted the driver.
Attachments:
infoOutput.txt -- script capture of the xenhost console as I was displaying
the configs, xm list outputs, ifconfig, brctl,
and the current route table.
winxpTest -- config file for the windows guest
dwm3 -- config file for my RHEL5 guest
winxpTestIPCONFIG.gif -- screen capture of ipconfig /all on win guest, also
ping and
tracert output
dwm3PingTracert.gif -- screen capture of ping test on the RH guest to show
that
the basic environment routes to the ping target.

Re: [Xen-users] windows XP Guest network doesn''t work
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The MAC address for the Windows guest seems odd. The Xen Wiki recommends: - --- Virtualised network interfaces in domains are given Ethernet MAC addresses. By default xend will select a random address, this will differ between instantiations of the domain. If it is required to have a fixed MAC address for a domain (e.g. for using with DHCP) then this can be configured using the mac= option to the vif configuration directive (e.g. vif = [''mac=aa:00:00:00:00:11'']). When choosing MAC addresses to use, ensure you choose a unicast address. That is, one with the low bit of the first octet set to zero. For example, an address starting aa: is OK but ab: is not. It is best to keep to the range of addresses declared to be "locally assigned" (rather than allocated globally to hardware vendors). These have the second lowest bit set to one in the first octet. For example, aa: is OK, a8: isn''t. In summary, an address of the following form should be OK: XY:XX:XX:XX:XX:XX where X is any hexadecimal digit, and Y is one of 2, 6, A or E. - --- (The full article is here: http://wiki.xensource.com/xenwiki/XenNetworking) Your MAC starts with 11 - 00010001 in binary, which makes it a multicast address (I think). Starting it with 12 would give 00010010, which I think should be fine. The MAC on the RH guest starts 00, which is also unicast, but I don''t think its defined as a locally administered MAC. So far, that''s the only thing I''ve noticed that could be problem. I''d suggest trying changing the MAC and seeing if that has any effect.

Martin, good eyes! I''ve been making up MACs for Xen installations for more than 2 years and foolishly, it never occurred to me to learn anything about MAC address architecture. I changed the first byte to 40 and it now appears to work.
