Hello everyone

I just noticed that my observium vm wasn't shutting down even after 120 seconds so in turn the zfs storage didn't unmount cleanly.

Is there an option to set kvm to force shutdown a vm that didn't go down in time? I would prefer not to have to edit the libvirt-guests init script if at all possible but if it's the only way, that would work too.

In that case I'd need a bit of help since I'm not very familiar with bash scripting.

Thank you!

Regards,

Marco

Hi
KVM doesn't try to do anything on its own with the VMs (doesn't try to shut them down e.g. when you shut down the host).

Are you using "libvirt" to handle the VMs or are you using your own scripts/commands?

I'm using "libvirt" and I integrated in my server's shutdown sequence this script (for this to work the VM has to have the service "acpid" running).

Cheers

Hmmm I could replace the libvirt-guests portion that stops vms with this code. That ought to work I expect.

Eeehhh, sorry I wasn't aware that something like that exists => maybe then it's just a matter of starting "acpid" in the guests?

The acpid service is running on both vms that won't shut down. Both are ubuntu 16.04s.

What does shut down is the untangle vm.

All of these machines shut down in a matter of seconds when issuing virsh shutdown DOMAIN on the shell. As far as I can see, libvirt-guests uses exactly the same command...

What's the "untangle vm"?
I integrated the script in my shutdown sequence (OpenRC) because I basically thought (and tested with my local PC) that libvirt did not care about the running hosts, which I admit being weird (as libvirt aims to be a mgmt engine for the VMs and should therefore take care of such basic things like the host going down), but which was kind-of-confirmed after finding the github post, but which does not make sense seeing the presence of "libvirt-guests.conf"... .

Mmmhhh and I see now that I do not start any "libvirt-guests" on my server when I boot - not sure if I don't because it did not work or else => do you start "libvirt-guests" when your server/PC boots?

Thx

Untangle is a debian based virtual firewall appliance.

And yes, my vms would start automatically if it weren't for the fact that the zfs filesystem they're residing doesn't come up cleanly due to not being able to unmount cleanly due to vms still running on it when it shuts down .

That's a checkmark you can set in virt-manager, if you're using that one.

I have created a script that runs after boot to clean zfs, mount everything and start all domains. However, instead of cleaning up what gets broken on every reboot, I'd rather it not break in the first place, you know?

I have incorporated parts of your script into libvirt-guests but I can only test it when the wife is done watching movies off the server

Got it, thanks
