Unable to remove host-only network adapter

[msmcknight]

Hi everyone,

I'm using vbox 4.3.8 on Solaris 11.1 x64 and when I try to remove the hostonly adapter using the vbox manager, I get the following error:

Failed to remove the host network interface vboxnet0
Callee RC: NS_ERROR_NOT_IMPLEMENTED (0x80004001)

How do I remove the host-only interface?

Thank you

Bogged similarly, I simply created a new machine. I do not remember the complete procedure (saving the hard disk etc.), but problems did not come up.

I'm actually trying to remove it completely. If I go under File --> Preferences --> Network, I want to remove the host-only adapter completely. I can remove it on a Windows host, but cannot seem to remove it on a Solaris host. Basically, I want to remove the driver completely so there is no hook into the network stack at all.

Thanks!

If you want to remove the driver, you'll need unplumb the interface (ifconfig vboxnet0 unplumb) and then rem_drv vboxnet.

Thank you... a few more questions...

Will that only remove the host-only interface, or will "rem_drv vboxnet" remove all network capability for the VM's?

Would it permanently remove the interface -- ie. would it reappear after a reboot?

What steps would I take to add it back should I decide to?

Thanks again,
-Michael

Removing vboxnet would removing "Host-only networking" functionality. It will not remove Bridged networking or NAT, Internal network functionality.

The driver should not get re-loaded after a reboot.

To re-add it you'd have to do:
add_drv vboxnet
