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.
