virt-install hangs and won't die. How to stop safely?

  • 772

I am having a problem where virt-install gets stuck in the very early stages and cant be killed (after saying "starting installation", but before the VM is visible in virt-manager).

Ctrl-C does not work to cancel virt-install, and systemctl restart libvirtd just hangs. I have to hard restart the machine. Even kill $libvirtPID just hangs. If I restart, restart hangs with a message of kvm: exiting hardware virtualization, and I have to hard restart.

For the moment, I am not asking for help with the cause of the hang, but rather I want to know whether there is a better/safer way to cancel a frozen virt-install.

    In my experience if something hangs that hard that plain kill is ignored, there isn't any friendly way to exit the hung applications. Maybe kill -9 will help, but if host reboot also hangs with messages about kvm it could very well be a kernel bug, in which case there's likely not much you can do to recover nicely.
