vbox vbox hostonly interfaces are not working

[rmomota]

Hello

I can't get VirtualBox hostonly interface working after I upgraded to VirtualBox 7.2
Seems DHCP is not giving the IP address.
I'm used to install minikube and test kubernetes containers and even that stopped working, I believe the cause is the not working vbox hostonly.
Is there a bug or something?

Thank you

I can't get VirtualBox hostonly interface working after I upgraded to VirtualBox 7.2

Working myself with host-only networks, I noticed the problem quite a while ago on the 7.2 version as well.

Except for NAT attached adapters, all other DHCP servers are broken on version 7.2. (latest available port/package version 7.2.14)

Despite the checkbox of the vboxnetX DHCP server is check, and dhcpservers list shows the server enabled, the hostonlyifs list shows it disabled.

Spoiler

% vboxmanage list dhcpservers

vboxmanage dhcpserver start --interface=vboxnet0 doesn't have an effect. In the hostonlyifs list DHCP stays "Disabled".

For the time being, you need to configure IP addresses manually, or setup a DHCP server on the host, listening on the vboxnetX interface, leasing on the 192.168.56.0 subnet.

It looks like there is no issue opened on https://github.com/VirtualBox/virtualbox/issues or a PR on https://bugs.freebsd.org .

But even when starting with a static IP address like
minikube start --cni cilium --static-ip 192.168.49.100
it doesn't seem to work

I was able to make it work.
Open virtualbox gui and open minikube console
Login with user 'root', no password
then create the following file
sudo vi /var/lib/boot2docker/bootlocal.sh

#!/bin/sh
# Add an alias static IP to the main network interface (e.g., eth0 or eth1)
ip addr add 192.168.59.100/24 dev eth1 label eth1:static

and then
sudo chmod +x /var/lib/boot2docker/bootlocal.sh

restart minikube and it should work
