DHCP server sometimes unable to assign a dynamic IP address to a host only network interface

Post by SaveMeTenMinutes »

I found several threads/bug reports (though much older) on the issue:
https://www.virtualbox.org/ticket/7905
viewtopic.php?f=6&t=37402
viewtopic.php?f=3&t=84811

The issue seems to occur at random. Roughly every other time I start the box. Worth noting (like the threads I've linked) that the NAT interface doesn't experience dynamic IP address assignment issues. I suspect that the DHCP component crashes at runtime as well because sometimes, after having been connected via SSH to the guest for awhile, the connection hangs and the interface becomes unusable.

Re: DHCP server sometimes unable to assign a dynamic IP address to a host only network interface

The threads that you quoted are 1) ancient and 2) mostly resolved.

There is a bug in the output of "VBoxManage list hostonlyifs" where the DHCP server is always shown as "Disabled", even though it's not. Can you make sure that this is indeed the case? Or even better, can you post the VirtualBox.xml file (ZIPPED)? It should be in your "/home/<you>/.VirtualBox" directory.

We're also going to need to see a complete VM log, from a complete VM run:
  • Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
  • With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
  • Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
