Yes, but installing a more recent version not from the official SLES repository makes me loose
my support.

This is the part i want to keep an eye on (virsh-domain.c)
:
static bool
cmdDestroy(vshControl *ctl, const vshCmd *cmd)
{
virDomainPtr dom;
bool ret = true;
const char *name;
unsigned int flags = 0;
int result;
if (!(dom = virshCommandOptDomain(ctl, cmd, &name)))
return false;
if (vshCommandOptBool(cmd, "graceful"))
flags |= VIR_DOMAIN_DESTROY_GRACEFUL;
if (flags)
result = virDomainDestroyFlags(dom, VIR_DOMAIN_DESTROY_GRACEFUL);
else
result = virDomainDestroy(dom); <=====================================
if (result == 0) {
vshPrintExtra(ctl, _("Domain %s destroyed\n"), name);
} else {
vshError(ctl, _("Failed to destroy domain %s"), name);
ret = false;
}
virshDomainFree(dom);
return ret;
}
Does that mean that virsh itself returns a true and write "Domain %s destroyed\n" if it successfully
destroyed the domain and otherwise returns a false and writes "Domain %s destroyed\n" ?

If i want to check success or not with virsh then the top-level API is enough for me.
