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 default network incorrectly. I wonder if it is possible to configure virsh so it uses -c qemu:///system by default? We know that this is not great, but we don't know a better way to use minikube with the kvm2 driver. The minikube vms are started for creating a development environment and during CI, and they cannot require a password or any complicated setup.

The $HOME/.config/libvirt/libvirt.conf client config file can contain uri_default = "qemu:///system" Or you can set per shell with export LIBVIRT_DEFAULT_URI=qemu:///system Or you can set it just for virsh with export VIRSH_DEFAULT_CONNECT_URI=qemu:///system See: https://libvirt.org/uri.html#default-uri-choice https://libvirt.org/manpages/virsh.html#environment With regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|

The $HOME/.config/libvirt/libvirt.conf client config file can contain
uri_default = "qemu:///system"
Or you can set per shell with
export LIBVIRT_DEFAULT_URI=qemu:///system
Or you can set it just for virsh with
export VIRSH_DEFAULT_CONNECT_URI=qemu:///system

Awesome, thanks!
