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 rpcsvc_program_actor
at rpcsvc.c:137
breakpoint already hit 2 times
3 breakpoint keep y 0x00007f903ef199f0 in
glusterd_set_clnt_mgmt_program at glusterd-handshake.c:359
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 ?
Best Regards,
Yin Yin

Hi, Harsh:
I've try your patch, but can't boot the vm.
[root@yinyin qemu-glusterfs]# virsh create gluster-libvirt.xml

the libvirt build the qemu/gluster command correctly, the qemu-kvm try to
run, but faile after a while, that cause the libvirt monitor connect failed.

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?
