Standardise LUXI call argument types
Currently, we have 4 types of arguments in LUXI calls:
- most common, a list of values- a single argument that is sent as a list of one element- a single argument that is sent by itself- a dictionary (only Query and QueryFields)...
Rename filter and filter_ to qfilter
We currently use 'filter' as the OpCode, QueryRequest and RAPI fieldname for representing a query filter. However, since 'filter' is abuilt-in function, we actually have to use filter_ throughout the codein order to not override the built-in function....
Add cluster netmask parameter
Add the master_netmask cluster parameter, that represents the netmask ofthe master IP, encoded as a CIDR suffix.
This parameter can be set via the --master-netmask of gnt-cluster initand gnt-cluster modify. The default behaviour is to be consistent with...
Split starting and stopping master IP and daemons
Make migration RPC non-blocking
To add status reporting for the KVM migration, the instance_migrate RPCmust be non-blocking. Moreover, there must be a way to represent themigration status and a way to fetch it.
Keep only one global RPC runner in Ganeti context
Instead of having one RPC runner per mcpu processor this will keep onlyone instance as part of the masterd-wide Ganeti context. Upcomingpatches will change the RPC runner to report pending requests to the...
DeprecationWarning fixes for pylint
In version 0.21, pylint unified all the disable-* (and enable-*)directives to disable (resp. enable). This leads to a lot ofDeprecationWarning being emitted even if one uses the recommendedversion of pylint (0.21.1, as stated in devnotes.rst)....

Add bdev_sizes RPC call

Re-create instance disk symlinks on activate
This patch implements recreation of instance disk symlinks when theactivate-disks operation is run. Until now, it was not possible tore-create these symlinks without stopping and starting or migrating aninstance as the RPC call where this is done was in instance startup...
