Networking not working in windows 10 kvm/qemu guest---SOLVED----


I’m running an up to date installation of manjaro-plasma. I’ve installed all the dependancies for kvm/qemu to work. The other night I created a virtual machine for windows and installed a trial version of windows 10 pro. The installation was a simple default installation and it went fine I completely updated the vm and even added a cd-rom drive to the vm to install the virtio-win drivers in the the virtual machine. However when I rebooted my pc the vm won’t start because it’s reporting the default newtork device was not found.
This is the error I get when I try to start the vm. Error starting domain: Requested operation is not valid: network ‘default’ is not active

Traceback (most recent call last):
File “/usr/share/virt-manager/virtManager/”, line 65, in cb_wrapper
callback(asyncjob, *args, **kwargs)
File “/usr/share/virt-manager/virtManager/”, line 101, in tmpcb

libvirt.libvirtError: Requested operation is not valid: network ‘default’ is not active
I’ve made sure the libvirt service is started with : sudo systemctl restart libvirtd.service
An idea what’s going on?

Update: I went to install a linux vm in qemu/kvm. I again used the vm creation wizard and aside from picking the .iso I’d use to install from and the hard drive size I just went with the defaults. After the machine was created and I went to start it a window popped up saying the network wasn’t started and would I like to start networking along with the vm. I selected yes and went through with the install and the vm installed without a hitch. I tried starting the win10 vm and that started as well. So…why isn’t qemu’s networking starting when I start the virtual machine manager?


Type sudo virsh net-autostart default on the CLI press enter and and KVM’s networking will start automatically
