Hello!
Anyone has succeed on making a kvm guest linux, say fedora 16, with
vmwgfx driver?
I want to make it work over dri interface, but probably without the
x-org, it will be some testbed for wayland builds.
My host is a fedora 16, with kernel 3.3.0-8, with a working dri card.
I run the kvm:
qemu-kvm -vga vmware -hda f16.kernel-3.3.1.qcow
When intro the guest OS, i try to modprobe kvm, drm, ttm and last vmwgfx.
I got the following output in dmesg:
[drm:vmw_driver_load] *ERROR* Hardware has no pitchloc
the probe failed with error -38
Any suggestion?
thanks!

IIUC the vmware device emulation was based on reverse-engineering the
linux xorg driver, not on a spec. As such it may be incomplete.
You can either reverse-engineer the linux driver for the missing bits,
or ask vmware for documentation.

Thanks!
Is there any other way on having at least 2d acceleration with qemu?
If it is possible, using ksm/drm.
Thanks!!!

I tried this one, but I have no /dev/dri/card0,
nor any module is loaded in the kernel that uses drm.

It doesn't use DRM/DRI yet. There is a userspace X driver,
xf86-video-qxl, that directly accesses the pci.
