KVM, how to add a previously created machine?

Question

Virtualization

Good afternoon! Using virt-manager (Debian 10, qemu-kvm, libvirt) I created a virtual machine, rolled back the system to the old state and it disappeared from the list of machines, is it possible to restore a previously installed virtual machine from a disk image?

Answer 1

Is it possible, having an HDD on hand, to recreate the configuration of the computer? Actually the machine is not only a disk. The configuration of the machine itself is stored in /etc/libvirt/qemu in the blabla.xml file, where blabla is the name of the machine.
Although you can try and create a new machine by importing a disk image.
