Cant set promiscuous mode on more than 4 NICs

[fr6nco]

Hi,

I needed to add more NICs to a ubuntu machine, but it allows only 4 via GUI, so remaining 4 I have added usin vboxmanage. However, it is not possible to set promiscuous mode on NIC indexed from 5-8.

I am attaching some outputs:

thomas@thomas-H61M-DS2:~$ vboxmanage showvminfo ubuntu_1204_ofsoftswitch | grep NIC

After I tried the following commands:

vboxmanage controlvm ubuntu_1204_ofsoftswitch nicpromisc5 allow-all

and

vboxmanage controlvm ubuntu_1204_ofsoftswitch nicproperty5 promiscuousModePolicy='allow-all'

but the result remained the same...

Expected result: NIC 5 is set to Promisc Policy - allow-all
Actual result: NIC 5 remained in promisc policy - deny

Actually what you observe is that the promisc settings done with 'VBoxManage controlvm' are not permanently saved. Which is most likely a bug. 'VBoxManage modifyvm' will store the setting permanently. 'controlvm' is for a running VM while 'modifyvm' is for a VM which is currently not running.

The fix is part of the VBox 4.3.24 release.
