Hello all, I am getting a error, when creating a sheepdog pool via libvirt. libvirt is compiled as: ./configure --prefix=/opt/libvirt --without-xen --with-yajl --with-storage-sheepdog=/opt/sheepdog Sheepdog is functional, when creating manually a vdi via "qemu-img" and than using as disk in libvirt. The error looks like this: internal error missing backend for pool type 9 The peace of log: 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=2 w=3, f=11 e=1 d=0 2013-09-18 14:51:27.580+0000: 14524: debug : virStoragePoolCreateXML:13588 : conn=0x7f1877937800, xmlDesc=      <pool type="sheepdog">         <name>mysheeppool</name>         <source>           <name>mysheeppool</name>           <host name='localhost' port='7000'/>         </source>       </pool> , flags=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=3 w=4, f=12 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=4 w=5, f=6 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=5 w=6, f=14 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=6 w=7, f=13 e=0 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=7 w=8, f=13 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=8 w=10, f=16 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollMakePollFDs:391 : Prepare n=9 w=12, f=17 e=1 d=0 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollCalculateTimeout:332 : Calculate expiry of 2 timers 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollCalculateTimeout:340 : Got a timeout scheduled for 1379515892580 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollCalculateTimeout:353 : Schedule timeout then=1379515892580 now=1379515887580 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollCalculateTimeout:361 : Timeout at 1379515892580 due in 5000 ms 2013-09-18 14:51:27.580+0000: 14522: debug : virEventPollRunOnce:627 : EVENT_POLL_RUN: nhandles=9 timeout=5000 2013-09-18 14:51:27.580+0000: 14524: debug : virFileClose:90 : Closed fd 18 2013-09-18 14:51:27.580+0000: 14524: debug : virObjectRef:293 : OBJECT_REF: obj=0x7f1877925550 2013-09-18 14:51:27.580+0000: 14524: debug : virAccessManagerCheckStoragePool:321 : manager=0x7f1877925550(name=stack) driver=QEMU pool=0x7f1864001340 perm=5 2013-09-18 14:51:27.580+0000: 14524: debug : virAccessManagerCheckStoragePool:321 : manager=0x7f1877929180(name=none) driver=QEMU pool=0x7f1864001340 perm=5 2013-09-18 14:51:27.580+0000: 14524: debug : virAccessManagerCheckStoragePool:321 : manager=0x7f1877925550(name=stack) driver=QEMU pool=0x7f1864001340 perm=2 2013-09-18 14:51:27.580+0000: 14524: debug : virAccessManagerCheckStoragePool:321 : manager=0x7f1877929180(name=none) driver=QEMU pool=0x7f1864001340 perm=2 2013-09-18 14:51:27.580+0000: 14524: debug : virObjectUnref:256 : OBJECT_UNREF: obj=0x7f1877925550 2013-09-18 14:51:27.580+0000: 14524: error : virStorageBackendForType:1114 : internal error missing backend for pool type 9 The pool XML: <pool type="sheepdog">         <name>mysheeppool</name>         <source>           <name>mysheeppool</name>           <host name='localhost' port='7000'/>         </source> </pool> Kind regards Giovanni
