That would be correct.

Most installations will give a default hostname in the OS. Most systems,
when requesting an IP from a DHCP server, will declare their hostname.
Most likely your Ubuntu Guest OS has the hostname UBUNTU-SERVER. Check the
BASH prompt.
DHCP servers can also supply the device it's hostname but I don't think
that's the case in your setup.

Your router's DHCP server most likely ignores the client hostname.
Use Wireshark (on your desktop) to capture the DHCP sequence if you want to
dig deeper into what's going on.
