Posted by Jordan Erickson in Linux, LNS Blogs

Today I wrote two simple bash scripts. The first one shuts down all of my running libvirt (+ qemu/kvm) guest virtual machines at once. The second script automates restarting all guests marked as ‘autostart’ in qemu. I’m using these in Debian 10 (Buster). The reason I made these scripts was to help in automating the […]

In contemplating the root of this […]
