Hi, Harsh:
I make some break in glusterd , and can gdb the qemu-kvm forked from
libvirtd.
break in glusterd:
(gdb) i b
Num Type Disp Enb Address What
1 breakpoint keep y 0x00007f903ef1a0a0 in server_getspec at
glusterd-handshake.c:122
2 breakpoint keep y 0x00000034f4607070 in

breakpoint already hit 2 times
3 breakpoint keep y 0x00007f903ef199f0 in

4 breakpoint keep y 0x00007f903ef1a0a0 in server_getspec at
glusterd-handshake.c:122
in rpcsvc_handle_rpc_call fun, it call rpcsvc_program_actor and return
right.
(gdb) p *actor
$13 = {procname = "GETSPEC", '\000' <repeats 24 times>, procnum =
2,
actor = 0x7f903ef1a0a0 <server_getspec>, vector_sizer = 0, unprivileged
= _gf_false}
but in
if(0==svc->allow_insecure&&unprivileged&&!actor->unprivileged){
/* Non-privileged user, fail request */
gf_log("glusterd",GF_LOG_ERROR,
"Request received from non-"
"privileged port. Failing request");
rpcsvc_request_destroy(req);
return-1;
}
so the server_getspec on server not be called, which cause qemu-kvm
progress failed.
my question:
1.(0==svc->allow_insecure&&unprivileged&&!actor->unprivileged)
which one
wrong here ?
You should be able to check this, step next in gdb and print value of
each var (to check which one is false). However, I think its more about
configuring glusterd correctly and less about the libvirt/qemu part of
it. I am willing to be corrected on this.
Let us know if Deepak's suggestion to set nfs.ports-insecure option
(might affect svc->allow_insecure in above statement) on gluster volume
works for you.
Thanks for testing my patch though !

Harsh

the libvirt build the qemu/gluster command correctly, the qemu-kvm

my question:
1.what's the libvirt hook funciton? could it affect the qemu-kvm
command?
2.It's hard to debug the qemu-kvm progress from libvirt, I try to
hang the glusterd for a moment, then to gdb the qemu-kvm, do your
have better methods?

This patchset provides support for Gluster protocol

It is based on the proposed gluster support in Qemu

<http://lists.gnu.org/archive/html/qemu-devel/2012-08/msg01539.html>
Just to be clear, that qemu feature didn't make the
deadline for 1.2,
right ? I don't think we can add support at the libvirt
level until
the patches are commited in QEmu, but that doesn't
prevent reviewing
them in advance . Right now we are in freeze for 0.10.0,
I am working on enabling oVirt/VDSM to be able to exploit this,
using harsh's RFC patches.
VDSM patch @ http://gerrit.ovirt.org/#/c/__6856/
<http://gerrit.ovirt.org/#/c/6856/>
An early feedback would help me, especially on the xml spec
posted here. My VDSM patch
depends on it.
thanx,
