DESCRIPTION
"nbdkit-libvirt-plugin" is an nbdkit(1) plugin that lets you access libvirt guest disks. Only read-only access is possible. It is implemented using the libvirt "virDomainBlockPeek" API. It can also be used over remote libvirt connections.
PARAMETERS
connect=URI This optional parameter specifies the libvirt connection URI. domain=DOMAIN This required parameter specifies the libvirt domain name (guest name). disk=DISK This required parameter specifies the guest's disk that we want to read. You can either give the path to the backing device (/path/to/disk) or the target name (eg. "sda"). In either case use "virsh dumpxml DOMAIN" to list possible disks. Look for "<source dev=...>" or "<source file=...>" or "<target dev=...>" in the XML.
