virsh: help: Drop 'id' from possible values for <domain> argument

[libvirt] [PATCH] virsh: help: Drop 'id' from possible values for <domain> argument

Posted by Erik Skultety 8 years, 2 months ago

At the moment, we can only rename inactive domains.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1490164

Theoretically, we could also remove this check from qemu_driver.c as it's a
useless check, given that a VM which passes the 'active' check is going to be a
persistent domain:

if (!vm->persistent) {
    virReportError(VIR_ERR_OPERATION_INVALID, "%s",
                   _("cannot rename a transient domain"));
    goto endjob;
}

Also, virshCommandOptDomainBy could be used instead of virshCommandOptDomain in
this case, but we might as well enable rename for active domains as well, who
knows and I don't think this is worth any more attention that just a help string
tweak.

NACK.

Virsh is a tool that runs client side, where as the check for non-running
status is done server side. An old virsh may be talking to a new libvirtd
which allows it for running guests. IOW, virsh should not make this kind
of assumption about the QEMU driver impl

Daniel

Do-oh! I clearly don't "libvirt" anymore, you're right, thanks.
