Public bug reported:

I am trying to launch my instance from cinder volume with heat template, but no success. 
My template will first create a volume from a glance image and then boot from this volume.
It seems that libvirt is looking for /var/lib/nova/instances/<instance-id>/disk, while my instance is booted from volume, the <instance-id> directory does not even exist.

In scheduler.log, I see:
Error from last host: compute-08 (node compute-08.local): [u'Traceback (most recent call last):\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 1305, in _build_instance\n    set_access_ip=set_access_ip)\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 393, in decorated_function\n    return function(self, context, *args, **kwargs)\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 1717, in _spawn\n    LOG.exception(_(\'Instance failed to spawn\'), instance=instance)\n', u'  File "/usr/lib/python2.6/site-packages/nova/openstack/common/excutils.py", line 68, in __exit__\n    six.reraise(self.type_, self.value, self.tb)\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 1714, in _spawn\n    block_device_info)\n', u'  File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py", line 2265, in spawn\n    block_device_info)\n', u'  File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py", line 3656, in _create_domain_and_network\n    power_on=power_on)\n', u'  File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py", line 3559, in _create_domain\n    domain.XMLDesc(0))\n', u'  File "/usr/lib/python2.6/site-packages/nova/openstack/common/excutils.py", line 68, in __exit__\n    six.reraise(self.type_, self.value, self.tb)\n', u'  File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py", line 3554, in _create_domain\n    domain.createWithFlags(launch_flags)\n', u'  File "/usr/lib/python2.6/site-packages/eventlet/tpool.py", line 179, in doit\n    result = proxy_call(self._autowrap, f, *args, **kwargs)\n', u'  File "/usr/lib/python2.6/site-packages/eventlet/tpool.py", line 139, in proxy_call\n    rv = execute(f,*args,**kwargs)\n', u'  File "/usr/lib/python2.6/site-packages/eventlet/tpool.py", line 77, in tworker\n    rv = meth(*args,**kwargs)\n', u'  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 708, in createWithFlags\n    if ret == -1: raise libvirtError (\'virDomainCreateWithFlags() failed\', dom=self)\n', u"libvirtError: cannot open file '/var/lib/nova/instances/3310bf49-82d0-467d-8b9b-de8d453cdef8/disk': No such file or directory\n"]
