Description of problem: ------------------------ __com.redhat_spice_migrate_info fails to deal with invalid parameter, cause qemu monitor hangs. Version-Release number of selected component (if applicable): -------------------------------------------------------------- qemu-kvm-0.12.1.2-2.232.el6.x86_64 How reproducible: ------------------ 100% Steps to Reproduce: -------------------- 1.boot guest with: /usr/libexec/qemu-kvm -enable-kvm -M rhel6.3.0 -smp 4 -m 4G -name win2008r2 -uuid 3f2ea5cd-3d29-48ff-aab2-23df1b6ae213 -drive file=nfs/win2008r2-64-virtio.qcow2,cache=none,if=none,rerror=stop,werror=stop,id=drive-virtio-disk0,format=qcow2 -device virtio-blk-pci,drive=drive-virtio-disk0,id=device-virtio-disk0 -netdev tap,script=/etc/qemu-ifup,id=netdev0 -device virtio-net-pci,netdev=netdev0,id=device-net0 -boot order=cd -monitor stdio -usb -device usb-tablet,id=input0 -chardev socket,id=s1,path=/tmp/s1,server,nowait -device isa-serial,chardev=s1 -monitor unix:/tmp/tt,server,nowait -vga qxl -spice port=5920,disable-ticketing 2.in qemu monitor: (qemu) __com.redhat_spice_migrate_info ? spice_server_migrate_connect: An undefined error has ocurred Actual results: ---------------- after step 2, qemu monitor hangs. Expected results: ------------------ Prompt error correctly, qemu monitor should not hang.
Reproduced this issue with steps and environment as follows: # uname -r ; rpm -q qemu-kvm 2.6.32-220.el6.x86_64 qemu-kvm-0.12.1.2-2.209.el6.x86_64 1.boot guest /usr/libexec/qemu-kvm -cpu cpu64-rhel6,+x2apic,family=0xf -rtc base=localtime,clock=host,driftfix=slew -M rhel6.2.0 -enable-kvm -name win7_x64 -smp 2 -m 2G -uuid bd85c229-6384-446d-bedd-c111008ecfce -boot menu=on -drive file=/nfs/win7sp1.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,aio=native,media=disk,werror=stop,rerror=stop -device virtio-blk-pci,drive=drive-virtio-disk0,id=virtio-blk-pci0,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=net0,mac=44:37:E6:5E:A3:F7 -spice port=9000,disable-ticketing -balloon none -monitor stdio -usb -device usb-tablet,id=input1 2.in qemu monitor: (qemu) __com.redhat_spice_migrate_info ? spice_server_migrate_connect: An undefined error has ocurred ---after step 2, qemu monitor hangs--- Verified this issue with steps and environment as follows: # uname -r;rpm -q qemu-kvm 2.6.32-251.el6.x86_64 qemu-kvm-0.12.1.2-2.255.el6.x86_64 1.boot guest with the above command line 2.in qemu monitor (qemu) __com.redhat_spice_migrate_info ? Parameter 'port/tls-port' is missing ---after step 2,qemu monitor works well--- So,this bug had been fixed.
