I have tried to reproduce the bug with: qemu-kvm-0.12.1.2-2.190.el6.x86_64 spice-client-0.8.2-3.el6.x86_64 spice-server-0.8.2-3.el6.x86_64 This is the command line that I use: /usr/libexec/qemu-kvm -enable-kvm -monitor stdio -m 8192 -smp 8,cores=4,threads=1,sockets=2 -cpu cpu64-rhel6,+sse2,+x2apic -spice port=8000,disable-ticketing -vga qxl -rtc base=utc,clock=host,driftfix=none -usbdevice tablet -no-kvm-pit-reinjection -device rtl8139 -M rhel6.2.0 rhel6.img Xiaoqing Wei, can you try to reproduce it with updated packages and the same command line. Is it enough for you to reproduce the crash with: 1. boot guess 2. connect to it with spicec 3. disconnect with spicec 4. go to step 2 Or do you reproduce it only by 1. boot guest 2. connect to it with spicec 3. repeat from step 1 until qemu crashes How much time do you leave the guest running? Have you tried with other guest images? (plain rhel6, nothing custom for testing for example) thanks (In reply to comment #2) > > /usr/libexec/qemu-kvm -enable-kvm -monitor stdio -m 8192 -smp > 8,cores=4,threads=1,sockets=2 -cpu cpu64-rhel6,+sse2,+x2apic -spice > port=8000,disable-ticketing -vga qxl -rtc base=utc,clock=host,driftfix=none > -usbdevice tablet -no-kvm-pit-reinjection -device rtl8139 -M rhel6.2.0 > rhel6.img > > Xiaoqing Wei, can you try to reproduce it with updated packages and the same > command line. > Or do you reproduce it only by > 1. boot guest > 2. connect to it with spicec > 3. repeat from step 1 until qemu crashes for me : 3. repeat from step 2, IIRC. > > How much time do you leave the guest running?

Did you disconnect the previous client? If yes, the you are doing then 1. boot guess 2. connect to it with spicec 3. disconnect with spicec 4. go to step 2 1. boot guess 2. connect to it with spicec 3. connect with a new spicec (previous one gets disconnected) 4. go to step 3 Can you confirm which steps you use to reproduce the bug? > > > How much time do you leave the guest running?

What is running in your guest for the case that fail? Sorry, but I need more details as I can't reproduce the crash.

Description of problem: qemu-kvm core dumps randomly Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.188.el6.x86_64 spice-server-0.8.2-3.el6.x86_64 spice-client-0.8.2-5.el6.x86_64 How reproducible: 2 / 10 Steps to Reproduce: 1.boot a guest with spice / qxl qemu-kvm ..... -spice port=8000,disable-ticketing -vga qxl ... 2. view guest by spicec -h ... -p ... 3. Actual results: sometimes qemu-kvm core dumps Expected results: both guest and host works fine.
