Hi all,
just brief, this small one breaks my qemu-system-x86_64 with:
qemu: qemu_cond_wait: Operation not permitted
My most complete qemu-starter:
/usr/local/qemu-2.3.0/bin/qemu-system-x86_64 -daemonize -usbdevice
tablet -enable-kvm -pidfile /var/run/qemu-server/3371.pid -monitor
unix:/var/run/qemu-server/3371.mon,server,nowait -vnc
unix:/var/run/qemu-server/3371.vnc,password -qmp
unix:/var/run/qemu-server/3371.qmp,server,nowait -nodefaults -serial
none -parallel none -device rtl8139,mac=00:F1:70:00:D2:B0,netdev=vlan0d0
-netdev
type=tap,id=vlan0d0,ifname=tap3371i0d0,script=/etc/fcms/add_if.sh,downscript=/etc/fcms/downscript.sh
-name 1155823384-7 -vga cirrus -k de -smp sockets=1,cores=1 -m 512
-device virtio-blk-pci,drive=virtio0 -drive

-drive

-drive if=ide,media=cdrom,id=ide1-cd0,readonly=on -drive
if=ide,media=cdrom,id=ide1-cd1,readonly=on -boot order=dc
Up to the former commit everything works well as expected.
Hope it helps,
Oliver.

If the iothread lock isn't taken by the main thread, the RCU callbacks
might run concurrently with the main thread. QEMU's not ready for that.
