[ovirt-users] QEMU hangup with SPICE console
Hello, our hypervisor nodes are running on FC19. virt-preview repos is activated. Windows VMs are using SPICE protocol. From time to time we see hangups of the windows machines. QEMU has 100% CPU and a perf report gives the following output: Samples: 70K of event 'cycles', Event count (approx.): 49527366887 51,76% qemu-system-x86 libspice-server.so.1.8.0 [.] 0x0005a6e8 41,15% qemu-system-x86 [vdso][.] 0x0701 2,09% qemu-system-x86 libc-2.17.so [.] clock_gettime 1,10% qemu-system-x86 libspice-server.so.1.8.0 [.] pthread_self@plt 0,60% qemu-system-x86 libpthread-2.17.so[.] pthread_self 0,53% qemu-system-x86 libspice-server.so.1.8.0 [.] clock_gettime@plt 0,27% qemu-system-x86 qemu-system-x86_64[.] 0x001d6238 ... No SPICE client is connected to the VM. Any idea how to isolate the error better? Markus Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.

Any idea how to isolate the error better? disable spice i suppose resolve this how about qxl drivers? installed or not? definitely check on spice and/or qemu list… Thanks, michal Markus InterScan_Disclaimer.txt___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Any idea how to isolate the error better? disable spice i suppose resolve this how about qxl drivers? installed or not? definitely check on spice and/or qemu list… installed spice debuginfo and got more details. Reason seems to be this bug: http://cgit.freedesktop.org/spice/spice/commit/?id=4019a8801d7a67035749562c0c1f403c24f36b0b As the CPU consumption is quite nasty I advise anyone who gets similar issues on FC19 nodes to jump onto FC20. spice-server 0.12.5 including the bugfix has been pushed to the testing repos and should be available the next weeks. https://admin.fedoraproject.org/updates/FEDORA-2014-6559/spice-0.12.5-2.fc20 Markus Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.
