vboxmanage dhcpserver add but client can't get DHCP ip

  • 772

This is the command I use in host OS, unfortunately guest OS still can't get the DHCP ip.

Both OS are running in Linux.

wolf@linux:~$ vboxmanage dhcpserver add --network=malfoy --server-ip=10.38.1.1 --lower-ip=10.38.1.110 --upper-ip=10.38.1.120 --netmask=255.255.255.0 --enable
wolf@linux:~$

Verification

wolf@linux:~$ vboxmanage list dhcpservers

    You might find the following question weird, but I've seen it solved most of the issues in VirtualBox.

    1. Have you installed VirtualBox Guest Additions?
    2. Have you rebooted the guest OS
    3. Have you rebooted the host OS
