Hello
Why is in qemu_conf.c caps initialized with 0 for offlineMigrate and
liveMigrate?
qemu_conf.c line 364 ff
virCapsPtr qemudCapsInit(void) {
struct utsname utsname;
virCapsPtr caps;
int i;
/* Really, this never fails - look at the man-page. */
uname (&utsname);
if ((caps = virCapabilitiesNew(utsname.machine,
0, 0)) == NULL)
virsh capabilities does not return <migration_features>
Is this a bug or doesn't it matter and is a mere cosmetical issue?
in virCapabilitiesNew() in capabilities.c line 51 and 52
caps->host.offlineMigrate and caps->host.liveMigrate is so set to 0.
Should this be fixed and both set to 1 when setting caps with
virCapabilitiesNew because if i do so i get the
with:
if ((caps = virCapabilitiesNew(utsname.machine,
0, 0)) == NULL)
[root@rr010 ~]# virsh capabilities
