Hi, I tried to install the packages on a freshly installed Debian 8 (jessie) system. It failed with the following error: # apt-get install vdsm ... Setting up vdsm (4.17.11-1) ... Usage: /usr/bin/vdsm-tool [options] <action> [arguments] Valid options: ... The offending command in vdsm.postinst script is: ... + vdsm-tool load-needed-modules Usage: /usr/bin/vdsm-tool [options] <action> [arguments] ... When run manually, vdsm-tool doesn't seem to accept any action, e.g.: # vdsm-tool configure Usage: /usr/bin/vdsm-tool [options] <action> [arguments] Valid options: -h, --help Show this help menu. -l, --logfile <path> Redirect logging to file. -v, --verbose Include warning (and errors) messages in log. -vv, --vverbose Include information (and above) messages in log. -vvv, --vvverbose Include debug (and above) messages in log. -a, --append Append to logfile instead of truncating it (if logging to a file). Note there are no vdsm-tool commands listed in the help output. And load-needed-modules action looks strange, I couldn't find it anywhere except the postinst script.
