SYNOPSIS
 nbdkit libvirt [connect=URI] domain=DOMAIN disk=DISK

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.

FILES

$plugindir/nbdkit-libvirt-plugin.so
    The plugin.

    Use "nbdkit --dump-config" to find the location of $plugindir.
