KVM live migration syntax

KVM live migration syntax

[Philipp Wehrheim]

Hey,

I lately tried to live migrate a VM but had to find out that the
syntax shown in the KVM examples and the actual syntax expected
by the code do not match.

from the Wiki:
	
	tcp:// migration protocol

But the code says (kvm-79/qemu/migration.c):
	
void qemu_start_incoming_migration(const char *uri)
{
    const char *p;

    if (strstart(uri, "tcp:", &p))   <===================
        tcp_start_incoming_migration(p);
    else
    ...

So the syntax expected by the code is *without* the //.

Am I missing something?

Thanks
flip

No, you aren't; KVM recently started using QEMU's live migration (which 
has the tcp:host:port syntax) as opposed to its own (as documented on 
the wiki, with the tcp:// syntax)
