The xend/server/SrvDomain.py includes:
def do_migrate(self, _, req):
fn = FormFn(self.xd.domain_migrate,
[['dom', 'int'],
['destination', 'str'],
['live', 'int'],
['port', 'int'],
['node', 'int'],
['ssl', 'int']])
return fn(req.args, {'dom': self.dom.domid})
Since FormFn does a check on the required parameter,
4077 /* Make the call. */
4078 ret = xend_op (domain->conn, domain->name,
4079 "op", "migrate",
4080 "destination", hostname,
4081 "live", live,
4082 "port", port,
4083 "resource", "0", /* required, xend ignores it
*/
"node", "-1", /* what does it do? */
"ssl", "0",
4084 NULL);
A diff is really nicer to avoid ambiguities !
Could probably fix it.
Well what happens if you make that change ? Is the migration
successful ?
If you can verify with the change ? Then it's worth checking further,
for example that this doesn't break older versions of Xen, which should
be the case, if i understand xend/Args.py correctly it will only use
parameters requested in teh spec so extra args will be dropped.
But I don't know if the right approach is now to
switch back to the development branch or, kindly request, a 0.4.6.1
We have no such patch in the devel branch that I can think of. And
I don't see the relation to a new release with a different numbering
scheme. Care to explain ?
