Running X11 on KVM

NOOB ALERT: I'm just starting with FreeBSD coming from a Linux/Solaris background.

I am running a Fedora 19 x86_64 bit system with KVM as my virtualization platform. I successfully install 9.1 (64bit) and I am now trying to get KDE4 installed. I installed the following: pkg_add -r xorg kde4. And I added this in my /etc/rc.conf file

Code: 
hald_enable="YES"
dbus_enable="YES"
local_startup="${local_startup} /usr/local/kde4/etc/rc.d"
kdm4_enable="YES"

I see this in the logs (it also displays on the console):

Code: 
Sep 17 15:45:44 minion kdm[858]: Cannot create/lock pid file /var/run/kdm.pid 
Sep 17 15:45:44 minion kdm[874]: X server died during startup 
Sep 17 15:45:44 minion kdm[874]: X server for display :0 cannot be started, session disabled 
Sep 17 21:14:15 minion kdm[871]: Cannot lock pid file /var/run/kdm.pid, another xdm is running (pid 855) 
Sep 17 21:14:15 minion kdm[855]: X server died during startup 
Sep 17 21:14:15 minion kdm[855]: X server for display :0 cannot be started, session disabled

When I try to start X manually; this is what I get:

I'm a FreeBSD noob... so not sure where to start to debug this. I think it has to do with KVM because I didn't have an issue with VirtualBox.

--C
 
Simply put you need to get a program to decompile the PCI headers in those memory sections it thinks are the offsets for the VESA routines. I just read that the utility mmiotrace is capable of following these routines and examining the actual stacks being executed in gdb. It's supposedly how they got the old Radeon cards to work on X11.
 
Would anyone share their xorg.conf for KVM? (I did it a few times, install freebsd FreeBSD (8.x/9.x) on KVM, but can not make the mouse work) I want try freebsd FreeBSD/desktop on KVM too. Thanks.
 
What is your GPU card? Look through lsof or something on linux. Then, check whether you have the correct driver installed and loaded from x11-drivers.
I could not find any info regarding your GPU card, and the xorg log shows that it did not recognize the card; most likely because the driver is missing.
