Note you just get a warning when failing to inject any of (key, net, metadata, admin_password) However if you've specified "injected_files" you'll get the presented exception on error. Now even though the specific error here is about guestmount being missing, just installing guestmount may not work unless the partition to inject to is "/dev/sda1". That's probably not the case, or otherwise the nbd method would have worked. OpenStack is currently hardcoded to inject to the first partition. Now you could have a complicated or arbitrary image layout with volume groups etc. so to get guestmount to inspect the image, and find the partition to inject you'd need to: Edit /usr/lib/.../nova/virt/disk/guestfs.py Add this line to the start of the mnt_dev() function: partition = -1 Restart the nova compute service. I'll prepare an upstream patch to make this configurable. cheers, Pádraig. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
