libvirtd fails to start
Last modified: 2011-02-04 11:47:28 EST
Description of problem: the libvirtd service won't start (stock F-13 system). Version-Release number of selected component (if applicable): libvirt-0.7.7-5.fc13.x86_64 How reproducible: always Steps to Reproduce: 1. libvirtd as root 2. 3. Actual results: 22:11:40.067: warning : qemudStartup:1150 : Unable to create cgroup for driver: No such device or address 22:11:40.301: warning : lxcStartup:1748 : Unable to create cgroup for driver: No such device or address 22:11:40.320: error : virStateInitialize:890 : Initialization of UML state driver failed 22:11:40.320: error : main:3160 : Driver state initialization failed 22:11:40.321: warning : qemudDispatchSignalEvent:385 : Shutting down on signal 3 Expected results: (libvirtd starts) Additional info: selinux in enforcing mode, no AVC denials. i'll be gone for a week without access to this machine, but after that i should be able to answer any questions you may have. sorry about the timing. also, got this line in /var/log/messages: Jul 26 21:48:25 localhost libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory
Add the following to /etc/fstab and libvirtd works again: cgroup /cgroup cgroup cpuset,cpu,cpuacct,memory,devices,freezer,net_cls
I had a similar problem. The reason on my machine was a corrupted qemu binary (some linklib was missing) that libvirt was trying to probe while starting. I believe I found it with export LIBVIRT_DEBUG=1 skipping over the iptables errors that libvirt tolerates to fail.
libvirtd has gone back to working for me since I filed this (without any action on my part other than installing updates). go figure.
