@subsection GlusterFS disk images
GlusterFS is an user space distributed file system.
You can boot from the GlusterFS disk image with the command:
@example
qemu-system-x86_64 -drive file=gluster[+@var{transport}]://[@var{server}[:@var{port}]]/@var{volname}/@var{image}[?socket=...]
@end example
@var{gluster} is the protocol.
@var{transport} specifies the transport type used to connect to gluster
management daemon (glusterd). Valid transport types are
tcp, unix and rdma. If a transport type isn't specified, then tcp
type is assumed.
@var{server} specifies the server where the volume file specification for
the given volume resides. This can be either hostname, ipv4 address
or ipv6 address. ipv6 address needs to be within square brackets [ ].
If transport type is unix, then @var{server} field should not be specifed.
Instead @var{socket} field needs to be populated with the path to unix domain
socket.
@var{port} is the port number on which glusterd is listening. This is optional
and if not specified, QEMU will send 0 which will make gluster to use the
default port. If the transport type is unix, then @var{port} should not be
specified.
@var{volname} is the name of the gluster volume which contains the disk image.
@var{image} is the path to the actual disk image that resides on gluster volume.
You can create a GlusterFS disk image with the command:
@example
qemu-img create gluster://@var{server}/@var{volname}/@var{image} @var{size}
@end example

@item GlusterFS
GlusterFS is an user space distributed file system.
QEMU supports the use of GlusterFS volumes for hosting VM disk images using
TCP, Unix Domain Sockets and RDMA transport protocols.
Syntax for specifying a VM disk image on GlusterFS volume is
@example
gluster[+transport]://[server[:port]]/volname/image[?socket=...]
@end example
Example
