nbdkit−libvirt−plugin − nbdkit libvirt plugin using
virDomainBlockPeek


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


 nbdkit libvirt domain=MyGuest disk=sda
 guestfish −−ro −−format=raw −a nbd://localhost

"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.



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.



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

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

"nbdkit−libvirt−plugin" first appeared in nbdkit 1.0.
