Comment 2 Daniel Veillard 2009-07-07 14:21:53 UTC

I really can't reproduce this:

[root@test2 ~]# virsh nodedev-list --tree  
computer
  |
  +-pci_8086_104c
  |   |
  |   +-net_00_19_d1_2d_c0_45
  |     
  +-pci_8086_244e
  +-pci_8086_2812
  +-pci_8086_2822
  |   |
  |   +-pci_8086_2822_scsi_host
  |   +-pci_8086_2822_scsi_host_0
  |   +-pci_8086_2822_scsi_host_1
  |   +-pci_8086_2822_scsi_host_2
  |   +-pci_8086_2822_scsi_host_3
  |   |   |
...
  +-pci_8086_29a2
  +-pci_8086_29a3
    

[root@test2 ~]# rpm -q libvirt
libvirt-0.6.3-13.el5
[root@test2 ~]# 

  There is something missing here... note that 

virsh nodedev-dumpxml computer

hangs on that box, it's bug
  https://bugzilla.redhat.com/show_bug.cgi?id=509261
for which we have a fix in the pipeline, but that one
I can't reproduce ! Can you make sure you didn't mix the
2 issues, if no can you run libvirtd under valgrind or gdb
and then rerun the command, then report your findings,

  thanks

Daniel

Comment 4 zhanghaiyan 2009-07-08 01:45:16 UTC

Only run command # virsh nodedev-list doesn't have this issue
If run command # virsh nodedev-list after run command # virsh nodedev-dumpxml computer will cause this issue.

Comment 5 Daniel Veillard 2009-07-08 11:31:57 UTC

Okay then it's a dup of 509261 which is fixed in libvirt-0.6.3-14.el5 and
should be on QA at this point. Just make sure you can't reproduce the issue
with that version,

  thanks,

Daniel
