_ValidateNetmask(cfg, netmask)

source code

Checks if a netmask is valid.

Parameters:

cfg (config.ConfigWriter) - The cluster configuration
netmask (int) - the netmask to be verified

Raises:

errors.OpPrereqError - if the validation fails

_VerifyCertificate(filename)

source code

Verifies a certificate for LUClusterVerifyConfig.

Parameters:

filename (string) - Path to PEM file

_GetAllHypervisorParameters(cluster, instances)

source code

Compute the set of all hypervisor parameters.

Parameters:

cluster (objects.Cluster) - the cluster object
instances - list of objects.Instance
instances - additional instances from which to obtain parameters

Returns: list of (origin, hypervisor, parameters)

a list with all parameters found, indicating the hypervisor they apply to, and the origin (can be "cluster", "os X", or "instance Y")
