Description of problem:
Create this bug to track the Bug 832156 not solved issue
Lockfailure action Restart can shutdown the guest but fail to start it
I re-write the reproduce steps for further testing since both libvirt and sanlock have changed a lot.


Version-Release number of selected component (if applicable):
libvirt-0.10.2-17.el6.x86_64
sanlock.x86_64 0:2.6-2.el6      


How reproducible:
100%
Steps to Reproduce:
----------------------------
1.Libvirt configuration
----------------------------
# service libvirtd stop

# getsebool -a | grep sanlock
sanlock_use_fusefs --> off
sanlock_use_nfs --> on
sanlock_use_samba --> off
virt_use_sanlock --> on

# tail -5 /etc/libvirt/qemu-sanlock.conf 
user = "sanlock"
group = "sanlock"
host_id = 1
auto_disk_leases = 0
/*Because the auto leases will have effect on the action , so close it , create lockspace and lease file mannully*/
disk_lease_dir = "/var/lib/libvirt/sanlock"

#tail -1 /etc/libvirt/qemu.conf 
lock_manager = "sanlock"
--------------------------------
2.Sanlock configureation
-----------------------------------
/*create lockspace file*/
#truncate -s 1M /var/lib/libvirt/sanlock/TEST_LS
#sanlock direct init -s TEST_LS:0:/var/lib/libvirt/sanlock/TEST_LS:0

/*change to permission to sanlock , since its default is root*/
#chown sanlock:sanlock /var/lib/libvirt/sanlock/TEST_LS:0

/*add lockspace to sanlock */
#service wdmd start
#service sanlock start
#sanlock client add_lockspace -s TEST_LS:1:var/lib/libvirt/sanlock/TEST_LS:0

/*you can use this command to check the status*/
#sanlock client host_status -s TEST_LS

/*create lease file*/
#truncate -s 1M /var/lib/libvirt/sanlock/test-disk-resource-lock
#sanlock direct init -r TEST_LS:test-disk-resource-lock:/var/lib/libvirt/sanlock/test-disk-resource-lock:0

/*change permission to sanlock*/
#chown sanlock:sanlock /var/lib/libvirt/sanlock/test-disk-resource-lock
-----------------------
3.Guest XML setting
---------------------
A normal shutdown guest  , add
....
<on_lockfailure>restart</on_lockfailure>
....
<lease>
<lockspace>TEST_LS</lockspace>
<key>test-disk-resource-lock</key>
<target path=’/var/lib/libvirt/sanlock/test-disk-resource-lock’/>
</lease>
...

to the guest.

#service libvirtd restart
#virsh start $domain

-----------------------------------------------------
4.Try to remove the lockspace when the guest is using.
-------------------------------------------------------
#sanlock client rem_lockspace -s __LIBVIRT__DISKS__:1:/var/lib/libvirt/sanlock/__LIBVIRT__DISKS__:0
/*If there is a better way to make the lockspace "lost " , plz correct me :) thanks*/

#virsh domstate $domain
shutdown

The guest can't start back.


Actual results:
Guest can't back

Expected results:
Guest back
