The OS definition also need to be upgraded. There is a new version of the

debian-etch-instance OS (0.2) that goes along with beta 2.

The master accepts commands over a Unix socket, using JSON

serialized messages separated by a specific byte sequence. For more

details, see the design documentation supplied with Ganeti.

Currently the master-node RPC is done using a simple RPC protocol

built using JSON over HTTP(S).

All Ganeti daemons re-open the log file(s) when sent a SIGHUP signal.

**logrotate**(8) can be used to rotate Ganeti's log files.

was for a deleted instance, it is needed to pass the FQDN of the

The algorithm doesn't rebalance the cluster or try to get the optimal

fit; it just allocates in the best place for the current step, without

taking into consideration the impact on future placements.
