[SOLVED] QEMU ("Network 'default' is not active") & ("Booting from Hard Disk...")

Querzion · March 2, 2023, 9:29pm

I’m starting to get a bit tired of the problems that I seem to get. Yesterday I apparently installed two drivers for the same thing, so my computer couldn’t even read the normal settings, and it never really started. I re-installed the computer, but not without caveats…

Problem Nr 1).

My VM is stuck at “Booting from Hard Disk...”.

[Solution] Import it with UEFI and not BIOS.

Problem Nr 2).

"Error starting domain: Requested operation is not valid: network 'default' is not active

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 108, in tmpcb
    callback(*args, **kwargs)

    ret = fn(self, *args, **kwargs)

    raise libvirtError('virDomainCreate() failed')
libvirt.libvirtError: Requested operation is not valid: network 'default' is not active
"

[Solution]
Fixed the first problem… Till the next boot.

How do I get it to autostart?

This is how you Autostart Virsh! sudo virsh net-autostart default

I thank my self for my ADHD, and now people have a guide if they get the same problems.

Can you clarify what your question is, specifically what’s your goal, what have you tried, what did you expect to see, and what did you see?

You seemed to have a problem with libvirtd-based VMs - I’m assuming you’re using virt-manager to manage these VMs?
It has a GUI to enable automatic network creation etc.

To clear up a minor misconception:

Nope, this is how you enable the automatic startup of the default network(which seems to be exactly what you want, what is your problem with this?).
virsh is just a client tool that connects to a running libvirtd instance, and manipulates VM, network or storage settings.

Can you tell us if your system uses the system instance or a user instance? (Right-click on the QEMU/KVM part in the virt-manager VM list, click details → overview → libvirt URI).

EDIT: Turns out you were quicker yourself. NVM, I guess.

I fixed the problem. I have a BOT VM, and it’s on autostart, but I imported it wrong, but imported the Win11 right, later on after a reboot, my VM’s wouldn’t start, and I eventually figured it out. Now it’s all okay on that front. I only have to fix the other problems that I have now. Which relates to OBS… I fixed one of maybe four things so far.

The drivers I installed yesterday made my computer not so happy, so i ended up reinstalling it and have been trying to fix all the stuff that I had fixed over time in the last install, that was incremental. It’s a lot of stuff that I have figured out and fixed over the past maybe 6 month’s. "/ And most of it is in memory, or in forum posts here. It’s a good memo page. hahaha
