Hi,
since qemu 2.4rc2, when I'm using iothreads, the vm is hanging, qmp queries are not working, vnc not working. (qemu process don't crash).
qemu 2.4 rc1 works fine. (don't have bisect it yet)
qemu command line:
qemu -chardev socket,id=qmp,path=/var/run/qemu-server/150.qmp,server,nowait -mon chardev=qmp,mode=control -vnc unix:/var/run/qemu-server/150.vnc,x509,password -pidfile /var/run/qemu-server/150.pid -daemonize -smbios type=1,manufacturer=dell,version=1,product=3,uuid=f0686bfb-50b8-4d31-a4cb-b1cf60eeb648 -name debianok -smp 2,sockets=2,cores=1,maxcpus=2 -nodefaults -boot menu=on,strict=on,reboot-timeout=1000 -vga cirrus -cpu kvm64,+lahf_lm,+x2apic,+sep,+kvm_pv_unhalt,+kvm_pv_eoi,enforce -m 8192 -k fr -object iothread,id=iothread-virtio0 -device pci-bridge,id=pci.2,chassis_nr=2,bus=pci.0,addr=0x1f -device pci-bridge,id=pci.1,chassis_nr=1,bus=pci.0,addr=0x1e -device piix3-usb-uhci,id=uhci,bus=pci.0,addr=0x1.0x2 -device usb-tablet,id=tablet,bus=uhci.0,port=1 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 -iscsi initiator-name=iqn.1993-08.org.debian.01.24b0d01a62a3 -drive file=/var/lib/vz/images/150/vm-150-disk-1.raw,if=none,id=drive-virtio0,cache=none,format=raw,aio=native,detect-zeroes=on -device virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,iothread=iothread-virtio0,bootindex=100
