Hi,
may i ask you about W2003 on domU ?
i'm experiencing a problem regarding 2GB RAM limit,
it doesn't look as W2003 problem, cause it does not boot with

mem=2048 or more

if there is mem=2047 everything is ok.

thx.

Subject: [Xen-users] Network card full virtualized windows

Good morning,
I installed on xen a windows XP and a Windows 2003 domU.
Windows operating system does not know the real network card
but it setup up
an AMD pcnet card 10mbps.
Is it possible to setup a full virtualized domU with a real
network card ?


Yes, that's what I'd expect (although you can choose one of three
different network card types [at least in the latest version(s)].

It is currently not possible to connect a real network card to a HVM
domain, as that requires address translation from the guest to the
machine memory addresses. If you look for a recent post by me in the
Xen-devel mailing list, you'll see what I mean.

Note that the 10Mbps is irrelevant, as this is a FAKE network card
supplied by the device model that the virtual machine uses to "simulate"
the hardware inside the virtual machine.

I installed also windows on a trial xen enterprise and real network
card seeems to work fine.


That's news to me, as I think Xen enterprise actually uses the same
Xen-kernel as the open source version, but has other add-ons.

What differences between xen and xen entrprise as far as network card
is concerned ?


I wouldn't know that - there is a mailing list for Xen enterprise.
