[Libguestfs] virt-inspector command hung up

[power off]

Hi,
I met a problem when using libguestfs-1.28.1 (centos 7.1) on a virtual machine.
Execute virt-inspector command to get OS information and the command hangs .


.......................
     Launching appliance, timeout set to 600 seconds
     libguestfs: launch: program=virt-inspcetor
     libguestfs: launch: version=1.28.1rhel=7,release=1.18.el7,libvirt
     libguestfs: launch: backend registered: unix
     libguestfs: launch: backend registered: uml
     libguestfs: launch: backend registered: libvirt
     libguestfs: launch: backend registered: direct
     libguestfs: launch: backend=libvirt
     libguestfs: launch: tmpdir=/tmp/libguestfsQp28Qo
     libguestfs: launch: umask=0027
     libguestfs: launch: euid=2016
     libguestfs: libvirt version = 1002008 (1.2.8)
     libguestfs: guest random name = guestfs-w8hcve9rhu0dve4a
     libguestfs: [00000ms] connect to libvirt
     libguestfs: opening libvirt handle: URI = qemu://session, auth = default+wrapper, flags = 0


command hung on here.We review the libguestfs soure code
It  seems that libguestfs call libvirt API virConnetOpenAuth failed but no returns.




And I set LIBVIRT_DEBUG=debug,and execute virt-inspect command again.
I find the command hung after function virFileFindResourceFull  from libvirt debug log.
.........
2017-03-11 07:19:09.246+000: 114046: debug: doRemoteOpen:882 : Peoceeding with sockname /run/user/2016/libvirt/libvirt-sock
2017-03-11 07:19:09.246+000: 114046: debug: virFileFindResourceFull:1608 : Resolved 'libvirtd' to ‘/usr/sbin/libvirtd’


there is no more debug log.


System run well  about half of a year before this problem happened. 


Any ideas?
PS: can I reboot virtual machine to resume it?


Thanks
