Subject: add default mapping of credentials to machine
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=743db933ed6bbcdd3ca87dd43c8164f6992bc89e;p=libvirt.git

add default mapping of credentials to machine

In the auth config file, it is currently required to have
an entry for each hostname to connect to, eg

  [auth-libvirt-prod1.example.com]
  credentials=prod

This is inconvenient when there are large numbers of machines
all with the same credentials. Add support for a default
entry:

  [auth-default]
  credentials=prod
