[ClusterLabs] KVM RHEL7 cluster

[Andrew Beekhof]

So…

your resource definition was:


      <clone id="libvirtd-clone">
        <primitive class="systemd" id="libvirtd" type="libvirtd">
          <instance_attributes id="libvirtd-instance_attributes"/>
          <operations>
            <op id="libvirtd-monitor-interval-60s" interval="60s" name="monitor"/>
          </operations>
          <meta_attributes id="libvirtd-meta_attributes">
            <nvpair id="libvirtd-meta_attributes-interleave" name="interleave" value="true"/>
          </meta_attributes>
        </primitive>
        <meta_attributes id="libvirtd-clone-meta"/>
      </clone>

but needed to be:

      <clone id="libvirtd-clone">
        <primitive class="systemd" id="libvirtd" type="libvirtd">
          <instance_attributes id="libvirtd-instance_attributes"/>
          <operations>
            <op id="libvirtd-monitor-interval-60s" interval="60s" name="monitor"/>
          </operations>
        </primitive>
        <meta_attributes id="libvirtd-clone-meta">
            <nvpair id="libvirtd-meta_attributes-interleave" name="interleave" value="true"/>
        </meta_attributes>
      </clone>

always set clone options on the clone, not the thing being cloned.

Once I made that change it seemed to behave.
