Running VBOX 5.0.20 on Centos7.X .

If you run into problems with 'Natnetwork' then there appears to be a 'namespace' issue when multiple users may be using the system. The messages you receive
are cryptic, failed to open/create the internal network NatNetwork. The workaround is to change you own NatNetwork namespace to a unique name. I don't recall this as being a requirement in the past, given it's for a unique user and this should be isolated, but it appears to now be a global! and as such is creating a resource name issue which causes the 'Permission Denied" messages. VERR_PERMISSION_DENIED ..This is very confusing...

Would you mind expanding a little bit into this?
• Do you have multiple users using the same host?
• All of them are running their VMs at the same time?
• Using NATNetwork? And it conflicts? What conflicts?
• Did I get it right? And what exactly do you mean by "namespace"?

I'm afraid that I have more questions than answers, so would you mind expanding your topic with details?
