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=...]
URI:
qemu-system-x86_64 -drive file=gluster[+@var{type}]://[@var{host}[:@var{port}]]/@var{volume}/@var{path}

"server":[@{"type":"tcp","host":"...","port":"..."@},
@{"type":"unix","socket":"..."@}]@}@}'
@end example
@var{gluster} is the protocol.
@var{transport} specifies the transport type used to connect to gluster
@var{type} 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.
tcp and unix. In the URI form, 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 specified.
@var{host} specifies the server where the volume file specification for
the given volume resides. This can be either a hostname or an ipv4 address.
If transport type is unix, then @var{host} field should not be specified.
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.
and if not specified, it defaults to port 24007. If the transport type is unix,
then @var{port} should not be specified.
@var{volume} is the name of the gluster volume which contains the disk image.
@var{path} is the path to the actual disk image that resides on gluster volume.
@var{debug} is the logging level of the gluster protocol driver. Debug levels
are 0-9, with 9 being the most verbose, and 0 representing no debugging output.
The default level is 4. The current logging levels defined in the gluster source
are 0 - None, 1 - Emergency, 2 - Alert, 3 - Critical, 4 - Error, 5 - Warning,
6 - Notice, 7 - Info, 8 - Debug, 9 - Trace
@var{logfile} is a commandline option to mention log file path which helps in
logging to the specified file and also help in persisting the gfapi logs. The
default is stderr.
@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}
qemu-img create gluster://@var{host}/@var{volume}/@var{path} @var{size}
