Hi,
I recently upgraded my machine from Ubuntu 9.10 to 10.4 (x86_64).
Ever since I upgraded my machine I cannot get qemu-kvm to start again.
I did not install the kvm package provided by Ubuntu. Instead I pulled
todays git from git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git and
ran ./configure && make -j6 && make install.
The configure output can be found here: http://pastebin.org/447003
I am using the following command line to boot qemu-kvm:
qemu-system-x86_64 -vnc :2 -k de -m 1024 -drive
file=/dev/sda,if=ide,index=0
/dev/sda? is this not the host disk?
When connecting to the VNC console I only get a black screen.
Does the monitor work? add -monitor stdio to the command line and type
'info registers' after you get the bla[nc]k screen.
This is the monitor output:
QEMU 0.13.50 monitor - type 'help' for more information
(qemu) info registers

This guest is very confused (what is it?)
Please enable ftrace:
# mount -t debugfs debugfs /sys/kernel/debug
# cd /sys/kernel/debug/tracing
# echo 100000 > buffer_size_kb
# echo kvm > set_event
# echo 1 > tracing on
run the guest and kill qemu immediately when you get to the blank screen
(use SDL so you can see it immediately). Then post
/sys/kernel/debug/trace somewhere.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
