Sorry this never received a response. I don't know about that particular crash but I assume it has been fixed. Closing as DEFERRED, but if anyone can still reproduce with newer libvirt please reopen with recent gdb output |
Created attachment 492703 [details] gdb generated log of issue Description of problem: libvirt crash when you run loads of "virsh domstat vm_name" Version-Release number of selected component (if applicable): 0.9.0 (and all older versions) How reproducible: It's easily reproducible with fedora core 14 and libvirt-0.9.0 Steps to Reproduce: 1.Install a fedora core 14 and configure libvirt-0.9.0 with netcf 2.Run some vms, and let some other vms be off 3.Put vms' nics on different bridge and isolated network 4.save this script to a file and name it putload: #!/bin/bash vms=( vm1 vm2 vm3 vm4 vm5 ) for i in `seq 10000`; do sleep 1 for vm in "${vms[@]}"; do virsh domstate $vm done done 5. run putload script more than 5 times at the same time like this ./putload & sleep 1 && ./putload & sleep 1 && ./putload & sleep 1 && ./putload & sleep 1 && ./putload & sleep 1 && ./putload 6. some times after some minutes, and sometime after some hours libvirtd crash NOTICE: be patient some times it takes more than 12 hours to crash. Actual results: libvirtd crash Expected results: libvirtd should be stable and not crash at all Additional info: I think it's related to netcf and fedora, because I haven't had such problem with debian and ubuntu as they don't use netcf. I attached gdb.txt to this bug report. It's really urgent because you can't run any monitoring and HA solution with virsh and libvirtd with such a bug, as you need to also watch libvirtd daemon.
