vboxnet0 (adapter 2) not found when running Mavericks

[o1sowise]

I just upgraded to OS X 10.9 Mavericks and none of my VMs will start.
All VMs get the error: vboxnet0 (adapter 2) not found
Can anyone suggest the changes I need to make to get around this?

P.S. I tried attaching the screenshot of the error and my adapter settings, but it says the quota has been exceeded...

I have exactly the same issue ... the only workaround is to reinstall (!!!) virtualbox ... every time I reboot the computer I have to reinstall virtualbox to make the adapters work!!!!

This is a BIG bug!!!

perhaps, Virtualbox fails to run.. kernel driver not loaded

Upgraded to new release 4.3.0 and all is good again!

Go to the Preferences of VirtualBox, you can add in vboxnet0 under network setting.
