Truncating host name for Netbios compatibility

Randomly, we see working VMs running for 20+ days and then the name of the host is changed which causing issues in the AD domain. What is setting off the name change? We can't have cloudbase-init randomly renaming machines.

Hello,

You need to change cloudbase-init configuration accordingly. By default, netbioshostname_compatibility=True in the config file.

In the cloudbase-init config file you have to set:

netbios_host_name_compatibility=False

Thank you,
