It looked to continue to add them if looking at something like output from "ip
link".
I was not however able to save the networks so the host always had "Unsaved Network
Changes".
I eventually needed to use the host and rebooted it and since they weren't saved they
were all gone on reboot.
So the takeaway i see here is that with Bridged Networks there is a softlimit of ~350 in a
Datacenter/Cluster due to the timeout of the VDSM. "vdsTimeout"
Is this something we could tune if we wanted have more than 350?
Im trying to think of what would happen if we increased that to anything else though.
