Description Franky Van Liedekerke 2013-06-12 08:07:02 UTC

Description of problem:

I just downloaded and compiled libvirtd on the same EL6 server as I did 1.0.4. Upon updating, libvirtd refuses to start, with this in the logfile (obfuscated the hostname by xxx's):

2013-06-11 13:43:49.154+0000: 3336: info : libvirt version: 1.0.6, package: 1.el6 (Unknown, 2013-06-06-14:57:07, xxxxxxxx)
2013-06-11 13:43:49.154+0000: 3336: error : virFileReadAll:1195 : Failed to open file '/sys/class/fc_host//host0/max_npiv_vports': No such file or directory
2013-06-11 13:43:49.159+0000: 3336: error : detect_scsi_host_caps:87 : Failed to read max_npiv_vports for host1
2013-06-11 13:43:49.163+0000: 3336: error : virFileReadAll:1195 : Failed to open file '/sys/class/fc_host//host0/max_npiv_vports': No such file or directory
2013-06-11 13:43:49.163+0000: 3336: error : detect_scsi_host_caps:87 : Failed to read max_npiv_vports for host2
2013-06-11 13:43:49.386+0000: 3336: error : virLockManagerPluginNew:175 : Failed to load plugin /usr/lib64/libvirt/lock-driver/lockd.so: /usr/lib64/libvirt/lock-driver/lockd.so: undefined symbol: virProcessGetStartTime
2013-06-11 13:43:49.386+0000: 3336: error : virStateInitialize:831 : Initialization of QEMU state driver failed
2013-06-11 13:43:49.386+0000: 3336: error : daemonRunStateInit:887 : Driver state initialization failed

So it seems two issues are present here:

1) it searches for /sys/class/fc_host//host0/max_npiv_vports for both host1 and host2. Imho this path needs to be /sys/class/fc_host//host1/max_npiv_vports and /sys/class/fc_host//host2/max_npiv_vports respectively.

2) the undefined symbol problem: seems a linking issue, no? The build worked just fine on rhel6 with all patches applied.

For now I reverted back to 1.0.4. Hope this helps to debug :-)

Also: I created a bug report for 1.0.4/1.0.6 concerning the init scripts:
https://bugzilla.redhat.com/show_bug.cgi?id=971408
Part of it (the virtlock socket) seems to be in the latest code already, but I believe the other issues mentioned are valid as well.

With friendly regards,

Franky

    Use the host number as the host number when constructing the sysfs path
    instead of the variable we are trying to fill.
