+qemu-kvm 0.12.1.2 crashes booting Ubuntu 9.10 with "-vga std"
+
+I have an Ubuntu VM that works fine without "-vga std" but crashes if I add "-vga std".  This is the full command line:
+
+qemu-system-x86_64 -vga std -drive
+cache=writeback,index=0,media=disk,file=ubuntu.img -k en-us -m 2048 -smp 2 -vnc

+
+I get this error:

+emulation failure, check dmesg for details
+
+I'm running kernel 2.6.32, and I have the kvm stuff compiled directly into the
+kernel.  There's nothing in dmesg about kvm at all.
+
+Note that in the VM grub comes up, but the VM dies when I boot the kernel.
+
+This command line works:
+
+qemu-system-x86_64 -drive cache=writeback,index=0,media=disk,file=ubuntu.img -k
+en-us -m 2048 -smp 2 -vnc :3102 -usbdevice tablet -enable-kvm &
+
+That is, removing "-vga std" fixes the problem.
+
+I recently added this option to both my Ubuntu and Windows XP VMs.  The Windows VM still works fine.  If Windows can detect that the graphics card has changed, then Ubuntu should also have no problem.  That being said, I added the std option when using 0.12.1.1, so there may be a qemu regression.
+
+I have reported this bug elsewhere:  http://bugs.gentoo.org/show_bug.cgi?id=299211
