[Xen-users] Vista Ultimate 32-bit install - VNC woes

[Danilo Godec <danilo.godec@xxxxxxxxx>]

Hi,

I'm running Xen server based on OpenSuSE 11 (Xen version
3.2.1_16881_04-4.2). I have several Linux DomU's that run perfect.

Now I need a temporary Vista install (for testing) so I used
'virt-manager' to install Vista. I used LVM based setup, Vista got 4GB
of memory (at least temporary) and 2 CPU's.

Initially things look good - I get the console window, Vista starts up
and I get to choose the language & keyboard layout. It then completes
copying files and starts ', the VNC connection is suddenly lost and I
can't get it back.

Here is what I find in /var/log/xen:

qemu-dm-43.log:

> xs_read(): vncpasswd get error.
> /vm/86d6b4aa-963a-4c89-958b-50d7c0afd11e/vncpasswd.

'xm dmesg' gives me a lot of these:
> (XEN) mm.c:645:d18 Non-privileged (18) attempt to map I/O space 00000000
> (XEN) mm.c:645:d18 Non-privileged (18) attempt to map I/O space 000000c0
> (XEN) mm.c:645:d18 Non-privileged (18) attempt to map I/O space 0000009f
> (XEN) mm.c:645:d18 Non-privileged (18) attempt to map I/O space 000000e0
> (XEN) mm.c:645:d19 Non-privileged (19) attempt to map I/O space 00000000
> (XEN) mm.c:645:d19 Non-privileged (19) attempt to map I/O space 000000c0
> (XEN) mm.c:645:d19 Non-privileged (19) attempt to map I/O space 0000009f
These addresses are re-occurring, but I can't really say whether it's
related (there is no timestamp with 'xm dmesg'...

I tried changing different things - stdvga=0/1, apic=0/1, pae=0/1 - but
none of these helped...

Dom0 is limited to 1GB of memory, but that shouldn't be an issue as we
haven't yet used more than 1/2 of that.

Any ideas?

    Best regards, Danilo
