Currently if the URI passed to virConnectOpen* is NULL, then we
- Look for LIBVIRT_DEFAULT_URI env var
- Probe for drivers
This changes it so that
- Look for LIBVIRT_DEFAULT_URI env var
- Look for 'uri_default' in $HOME/.libvirt/libvirt.conf
- Probe for drivers
This adds support for a libvirt client configuration file
either /etc/libvirt/libvirt.conf for privileged clients,
or $HOME/.libvirt/libvirt.conf for unprivileged clients.
It allows one parameter
uri_aliases = [
"hail=qemu+ssh://root@hail.cloud.example.com/system",
"sleet=qemu+ssh://root@sleet.cloud.example.com/system",
]
Any call to virConnectOpen with a non-NULL URI will first
attempt to match against the uri_aliases list. An application
can disable this by using VIR_CONNECT_NO_ALIASES
