I am running qemu-kvm-0.13.0 rc1 starting qemu like so: /root/qemu/bin/qemu-system-x86_64 -cpu host -enable-kvm -drive file=/root/qemu/w2k3_server.raw,if=virtio,aio=native -net nic,model=virtio,macaddr=52:54:00:12:34:56 -net tap,ifname=tap0 -localtime - usb -usbdevice tablet -vga std -vnc :25581 -monitor stdio -m 512 -runas rick Every now and again, qemu will up and quit leaving only the following message: qemu: qemu_mutex_lock: Invalid argument At the moment I can't stop what I'm doing to go learn how to debug qemu, but I'd be happy if anybody is interested in suggesting something I could do to provide some info about this bug... Would it be helpful to build with -O0 -g and run in gdb, then get a bt when it dies? I haven't put this into production yet, so I can still afford downtime & re- compiles...etc. thanks.. host machine is: 2.6.32-gentoo-r7 x86_64 Intel(R) Xeon(R) CPU E5450 @ 3.00GHz GenuineIntel GNU/Linux guest os is Windows Server 2003, Standard Edition.
