<div>OpenVZ it self allows creation of container id with 10 chars. But it doesn't allow the ctid to be used in the interface name.</div>
<div><br>
</div>
<div>Is this a known limitation? I seams inconsistent to me to allow CTID of 10 chars but not to be fully supported in the veth support of VZ.</div>
<div><br>
</div>
<div>Could this be fixed?</div>
</div>

<div>Linux applies 15 chars limitation on a network device names. So, the only fix we could do here – is to prohibit 10 chars for CTID and permit only 9 chars. But due to backward compatibility reasons, I doubt it worths to do now.</div>
