Linux Mint gets lost when I connect lan cable (also issues with Windows 10 VM)

[Claudio Chinicz]

Hi All,

My Linux Mint VM works ok when the notebook is connected to wifi only.
When I connect the lan cable I see the icon in the upper right corner
indicating both wifi and wired connections are available and this VM
looses internet connection. In the VM, Linux still sees it is connected
("wired" is the default - eth) but without internet connection.

If I disconnect the lan cable the VM sees internet connection as before.

By the way, my Windows 10 VM sees both but if I'm using wifi and connect
the cable or vice versa, I have to shut it down (and everything else
that uses sys-firewall) and restart sys-net.

I need to connect through lan cable in order to access corporate AD
resources.. otherwise I'd use only wifi and forget about this issue.

Thanks in advance for any insight from the community,

Claudio

My solution: split sys-net to sys-net-wifi and sys-net-eth and assign the respective controllers to them. Also split sys-firewall.

This way you will have two completely independent networks and firewalls, and you can switch AppVMs between them as you wish, even while they are running.

When you are not phisically at work, you can shut down sys-net-eth and sys-fw-eth to save ram.

Hi, Thanks again for your answer.

I've cloned sys-net as sys-net-wifi-only and started it, but when I
click on the icon no networks display. I've restarted Qubes but still
this second net VM does not display any networks.

Any ideas?

Regards,

You did allocate your wifi card to sys-net-wifi and ensure that it is
loaded correctly there?

[Claudio Chinicz]

Yes, I've done it. On dom0 I've issued command "qvm-pci attach
--persistent disp-sys-net <backend>:<bdf>" and afterwards my new
sys-net-wifi did not start because the device is in use (I suppose by
sys-net).

Any ideas?

Thanks,

Claudio

Depending on how you configured sys-net you may have to reboot after
removing the wifi from sys-net before it becomes available to use in
your new sys-net-wifi.

Shutdown sys-net - remove the wifi adapter - reboot - start sys-net -
start sys-net-wifi

Thanks!
