Hi,
I'm having a bit of trouble with my opnestack setup (icehouse) in our
lab when I try to launch a new instance.
In nova I get the following error :
2014-07-30 14:19:15.780 13528 TRACE nova.compute.manager [instance:

6df99b40-0171-4a52-b362-832d1556c589] Stderr: 'iscsiadm: No session
found.\n'
I tried to run iSCSI discovery to the cinder node and I can't connect to it.
The cinder node has two interfaces (10.0.2.15 and 192.168.100.32) on two
separate networks. 10.0.2.0/24 is our management network and hosts
aren't allowed to talk to each other on that network (only to a
management host) thus there can't be any iscsi session established over
that link.
The volume is correctly created on the target node and tgtadm shows the
correct configuration
If I try to establish an iSCSI session with the target at 192.168.100.31
it succeeds.
My question is, how can I specify the ip address of the target that
should be used (my guess would be in the nova.conf but I'm quite new to
openstack so I might be wrong and I haven't found any option in the
nova.conf file). Can someone describe how openstack "discovers" the ip
address of the iSCSI provider and how it behave if the provider has
several interfaces ?
Thank you already for your help.
Olivier
