Guest OS customization - hostname added "-0"

[kallischlauch]

hey everyone,

came across something I never saw before.

customization script is set to change the os hostname to whatever the VMname is.

today we had a VM, that instead of hostname3B it ended up as hostname3-0 (last letter removed and -0 added.

our automation script did everything else correctly: vm-name ok, dns entry ok, cno ok ... why would guest cusztomization decide to change the hostname (add this suffix?)

i checked sysprep log in windows\Panther and that set it to this weird hostname, but it seems it was instructed by it as the unattend.xml showed as such (see computername)

thanks for any ideas

Check the customization specification and make sure that the below check box is cleared.

Append a numeric value to ensure uniqueness

I have the same problem while using powercli to deploy a new VM with OS Customisaitons. The Vm name itself is fine but the OS name has -0 at the end. The option to append a number at the end is not available as Use vm name option is ticked in the OS customisation/COmputer name section. Also this happens randomly, some VMs were named correctly on same cluster, same datastore etc.

Check this thread might help you: Linux hostname issue

The person in that thread resolved by doing the following:

""I worked around this by substituting "-NamingScheme "Fixed" -NamingPrefix "$VMName""

As a troubleshooting step he also tried to use the wizard instead of the script and it worked fine.
