DESCRIPTION

16       "nbdkit-libvirt-plugin" is an nbdkit(1) plugin that lets you access
17       libvirt guest disks.  Only read-only access is possible.  It is
18       implemented using the libvirt "virDomainBlockPeek" API.  It can also be
19       used over remote libvirt connections.
20

PARAMETERS

22       connect=URI
23           This optional parameter specifies the libvirt connection URI.
24
25       domain=DOMAIN
26           This required parameter specifies the libvirt domain name (guest
27           name).
28
29       disk=DISK
30           This required parameter specifies the guest's disk that we want to
31           read.
32
33           You can either give the path to the backing device (/path/to/disk)
34           or the target name (eg. "sda").
35
36           In either case use "virsh dumpxml DOMAIN" to list possible disks.
37           Look for "<source dev=...>" or "<source file=...>" or
38           "<target dev=...>" in the XML.
