Re: [libvirt] [PATCH 0/1] Fix pool create when pool already exists

  Hum, I tried to assert the level of damage this bug generates and
I have been surprized by the following:

virsh # pool-create /tmp/pool.xml
Pool testpool created from /tmp/pool.xml

virsh # pool-list
Name                 State      Autostart
-----------------------------------------
testpool             active     no

virsh # pool-create /tmp/pool.xml
error: Failed to create pool from /tmp/pool.xml
error: internal error storage pool already exists

virsh # pool-list
Name                 State      Autostart
-----------------------------------------
testpool             active     no

virsh #

  I.e. on an unpatched libvirtd, I can hit the error, but the pool still
shows up, so I'm wondering what's the effect of the 
  virStoragePoolObjRemove(&driver->pools, pool);
that we are avoiding here... it should remove the pool from the list,
but I'm not seeing this, so I'm a bit puzzled...
