How to configure the default connection for virsh

We are using minikube vms, which require adding the user to to libvirt group[1]. We use `virsh -c qemu:///system` for debugging these vms or related libvirt networks. Using virsh without specifying the '-c' argument is a common mistake that leads to trouble, for example creating the libvirt

Re: Export checkpoint/bitmap from image on qcow2

long backup (e.g full backup, or incremental backup with a lot of data) blocks usage of the vm during the backup. You can start/stop/migrate a vm while it is being backed up and the backup can run on another host in the cluster (if using shared storage). Nir > On 12/18/23 18:44, Nir Soffer
