Default is not active.

English Virtualization

My virtual machine does not start, it tells me default is not active.

Through google I found a topic on this forum and tried something.

Did I find the problem, and how to fix it permanently ?

I already found I can get it working until the next reboot with

sudo virsh net-start default

Hi
Run;


virsh net-autostart default

Ref: libvirt: NAT forwarding (aka "virtual networks")

Thank you, that fixed it. :slight_smile:

Can I have qemu stop running when I quit kvm virtual machine manager ?

I already tried to stop qemu-system-x86_64 ( ctrl +esp) but it refuses to stop.

Hi
You have to stop/shutdown the virtual machine, then exit virtual-manager?

Now I finally understand, how this works.

When I choose in virtual manager, shutdown, with win 10 selected, I see windows shutdown, and then vm reports guest not running.

After this nothing qemu under running processes. :slight_smile:

If I choose quit from the top left menu, I only stop the virtual manager, not the virtual machine. (so qemu keeps running)

Hi
Correct, you can always use virsh from the command line to start/stop as well…
