Retrieving the guest host name is a very useful feature for virtual management
|
|
|
46bd62 |
systems. This information can help to have more user friendly VM access
|
|
|
46bd62 |
details, instead of an IP there would be the host name. Also the host name
|
|
|
46bd62 |
reported can be used to have automated checks for valid SSL certificates.
