[Xen-users] VESA BIOS in HVM emulation? (64 bit)

["Csillag, Kristof \(GE Healthcare, consultant\)" <Kristof.Csillag@xxxxxx>]

Hi there!

I am running a 64bit linux guest in HVM mode on a 64bit (xeon) workstation.
I am trying to get X to work.

The default cirrus driver is fine, but I need 1280x1024, 24 bpp mode, which
is not available in it.

So I switched to the standard VESA emulation mode by adding
stdvga=1 in the domain config file. (This mode is supposed to support 
higher resolution modes unsupported by the Cirrus emulation.)

This changed the loaded vga bios.
(Even lspci lists a different device now.)

But here comes the probelem:

When I try to start X, it says this:

------------------------------------
[...]

(II) VESA: driver for VESA chipsets: vesa
(II) Primary Device is: PCI 00:02:0
(--) Assigning device section with no busID to primary device

[...]

(II) Unloading /usr/X11R6/lib64/modules/libvbe.a
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

------------------------------------------------------------

How can I fix this?
