virtualbox.org

I have 2 Host-Only Networks: vboxnet0 & vboxnet1 with IPv4 192.168.2.1 for vboxnet0 and 192.168.4.1 for vboxnet1.
First network works fine, but when a start guest OS on vboxnet1 something happens and VirtualBox changes ip on vboxnet1 to 192.168.2.1! What's wrong? I tried to reboot, to down and up interface, to sudo launch.. But every time I start guest OS on vboxnet1it changes ip!

What does this look like?

NetworkName: HostInterfaceNetworking-vboxnet0
IP: 192.168.58.100
NetworkMask: 255.255.255.0
lowerIPAddress: 192.168.58.101
upperIPAddress: 192.168.58.254
Enabled: No

NetworkName: HostInterfaceNetworking-vboxnet1
IP: 192.168.4.1
NetworkMask: 255.255.255.0
lowerIPAddress: 192.168.4.101
upperIPAddress: 192.168.4.254
Enabled: No

I don't use dhcp.

Ok what does this give? If that is not correct try using To correct it.

Before launchine virtual machine it's correct:

After launching Virtual Machine it's changes -

Well I think your out of luck then see this from the manual

Host-only networking. Creation/deletion of host-only adapters are supported
for Windows hosts only presently. On other platforms, there is one fixed hostonly
interface called “vboxnet0” presently. This will change in a future release.

But it can't be far off as it tries to do it so in a few releases....
You could try adding a ticket to the bugtracker if it should work and the manual is wrong.

Thanx a lot!)
I'll try to add a ticket)

I'm very interested in a solution to this as well. It appears there is already a ticket for it, but not much activity on it recently.

Has anybody else had any luck?
