Description:
Update 5.1.24 breaks host-only networking for me. Both standard and LTS kernel are affected. Other than this the VMs seem to work fine, the host simply does not have a route to the VM. I have not done any manual configuration on NetworkManager, which works fine with virtualbox<5.1.24.
I was unable to find any indication of this in Virtualbox logs. Everything looks normal and the kernel modules load fine.

Additional info:
* virtualbox 5.1.24
* virtualbox-host-{modules-arch,dkms} 5.1.24
* linux{,-headers} 4.11.9-1 / linux-lts{,-headers} 4.9.37
* networkmanager 1.8.2-1

Steps to reproduce:
Install the newest Virtualbox version, start a VM with previously working host-only networking and try to ssh or ping to it.
This task depends upon

I can confirm this. Upgraded to 5.1.24 and host-only networking broke for the VMs. I was able to ssh into them, but not ping them. Rolled back to 5.1.22 to have host-only networking working.

The changelog [0] has one entry about host-only networking...
Possibly that broke anything for us?

It looks like it. At the very least it should remove the opt-deps on net-tools.
Currently I'm not able to find the exact changes in the implementation to confirm this, but if the referenced ticket [1] is any indication it might now use iproute2. However, it does not work on my machine, even with iproute2 installed.
