VM Image on Archipelago volume is specified like this:
file.driver=archipelago,file.volume=<volumename>[,file.mport=<mapperd_port>[,
file.vport=<vlmcd_port>][,file.segment=<segment_name>]]
'archipelago' is the protocol.
'mport' is the port number on which mapperd is listening. This is
optional
and if not specified, QEMU will make Archipelago to use the
default port.
'vport' is the port number on which vlmcd is listening. This is
optional
and if not specified, QEMU will make Archipelago to use the
default port.
'segment' is the name of the shared memory segment Archipelago
stack is
using.
This is optional and if not specified, QEMU will make Archipelago
to use
the
default value, 'archipelago'.
Examples:
file.driver=archipelago,file.volume=my_vm_volume
file.driver=archipelago,file.volume=my_vm_volume,file.mport=123
file.driver=archipelago,file.volume=my_vm_volume,file.mport=123,
file.vport=1234
file.driver=archipelago,file.volume=my_vm_volume,file.mport=123,
file.vport=1234,file.segment=my_segment

Judging by configure output in v2.3.0-rc2, QEMU seems to rely on
libxseg, which is GPL-3.0+: https://github.com/grnet/libxseg
How can anyone legally build this backend then? o.O
Any chance libxseg can be relicensed to GPL-2.0+?
Hello Andreas,
indeed the license has changed a few months after submitting the
patch for
the block driver to QEMU. I have already contacted the
administration
of GRNET which is responsible for this change asking them about the
aforementioned problem. I am waiting for the reply and hopefully we
will
resolve this license matter.
In the meantime I've sent a patch to disable Archipelago by default
in
./configure ("[PATCH for-2.3] configure: disable by default and warn
about libxseg GPLv3 license"). You are CCed on the email.
The intention is to reduce the chance of users accidentally compiling
binaries with license problems. Archipelago support is still
available but it must be explicitly enabled using ./configure
--enable-archipelago.
Stefan
For the moment I totally agree with the proposed patch.
Regards,
Chrysostomos.
