KVM+QEMU: Virtual Machine Manager can't connect and how to do networking for guests with multiple network interfaces?

Hi,

I have a server with 1 x onboard network interface and a PCIe card with Intel 2 x network interface.

The network uses VLANs and the guests needs to connect to different VLANs.

The onboard network interface is used for administration of the server, while I want the 2 x network interfaces to connect to two different VLANs. Multiple guests should be able to connect through the same interface.

I’ve read both documentation and in the forum, but can’t seem to get an overview on how to do this - I guess I have to configure a bridge interface? Does anyone know of a step-by-step guide?

I was trying to use Virtual Machine Manager, but I get an error when trying to connect (I have tried to disable the firewall on the server using Yast2).

Error:
Unable to connect to libvirt qemu+ssh://user@10.1.1.100/system.

Configure SSH key access for the remote host, or install an SSH askpass package locally.

Libvirt URI is: qemu+ssh://user@10.1.1.100/system

Traceback (most recent call last):
File “/app/share/virt-manager/virtManager/connection.py”, line 932, in _do_open
self._backend.open(cb, data)

Both the client (Tumbleweed) and the server (Leap) got the openssh-askpass, openssh-askpass-gnome and gcr3-ssh-askpass installed.
Anyone knows why I can’t connect? Root privileges or user needs to be member of a group?

I finally got Virtual Machine Manager to work. After an uninstall from Gnome Software, and install via zypper another error showed and after adding my user to libvirt and qemu I can now login from my client on the server using virt-manager.
