As I'm working with Vbox and GNS3 at some point I update my network adapters mode and we have 8 network adapters in Version 5.1.22 r115126 (Qt5.6.2)
as we know we can modify that for only 4 adapters in settings >> network .

Now, I want to edit the other 4 adapters , please support how to do this

For more than four adapters you just have to use the CLI commands.

ok,
we i tried to apply the below commands with cmd in virtualbox directory C:\Program Files\Oracle\VirtualBox>" it didn't work and said that : VBoxManage modifyvm com.cisco.ios-xrv_1 --macaddress<5-8> auto The system cannot find the file specified


commads as per below where my vm name is "com.cisco.ios-xrv_1 "

VBoxManage modifyvm com.cisco.ios-xrv_1 --nic<5-8> none

VBoxManage modifyvm com.cisco.ios-xrv_1 --nictype<5-8> virtio

VBoxManage modifyvm com.cisco.ios-xrv_1 --nicpromisc<5-8> allow-all

VBoxManage modifyvm com.cisco.ios-xrv_1 --cableconnected<5-8> on

VBoxManage modifyvm com.cisco.ios-xrv_1 --macaddress<5-8> auto

If your host PC is Wndows, your command window needs to be operating in the folder that Vboxmanage.exe exists in.

Before running a Vboxmanage command run this:
Also, <5-8> is not a valid command line argument. <5-8> means to pick a number between 5 and 8 and enter that number instead of <5-8>.

thanks for responding

but when applying the below :
VBoxManage modifyvm com.cisco.ios-xrv_1 --nic 5 none

VBoxManage modifyvm com.cisco.ios-xrv_1 --nictype 5 virtio

VBoxManage modifyvm com.cisco.ios-xrv_1 --nicpromisc 5 allow-all

VBoxManage modifyvm com.cisco.ios-xrv_1 --cableconnected 5 on

VBoxManage modifyvm com.cisco.ios-xrv_1 --macaddress 5 auto

that error line appeared :
VBoxManage.exe: error: --nic: RTGetOpt: Command line option needs an index.

Did that error message happen for all the commands or just one? And if one, which one?

Also, the command may be "--nic5" instead of "--nic 5", etc. There's no space between the letters and the < in the manual.

Done.
you can notice here that adapter5 is gone .

and there's an issue here , how can I see and revise what I have done .
id there is anyway to show configuration for network adapters which was edited ?

I have never tried entering these commands, maybe you jus need to run them all again?

it's the same for me as I always used to work with 4 adapters not more.
