Hi, I just add NFS as backend . Now, I want to launch an instance so it will be bootable from a nfs shared device .( and then ( it's my hope) may migrate to another compute node) ( i.e. I boot from an .iso image ) I don't find how , in the following nova boot command, to specify that I want that a "nfs" volume will be created to hold this instance : nova boot --image CentOS-7-ISO --block-device source=blank,dest=volume,size=10,shutdown=preserve --nic net-id=73d765a3-edca-4ac4-822d-1d0f30cc959b --flavor 2 CentOS-7-Bootable-Image Thx for help Regards, Jean-Pierre RIBEAUVILLE +33 1 4717 2049 [axway_logo_tagline_87px] -------------- next part -------------- An HTML attachment was scrubbed...
