PaulAngus commented on issue #1253: CLOUDSTACK-9184: [VMware]
vmware.ports.per.dvportgroup global setting is not useful from vCenter 5.0
onwards
URL: https://github.com/apache/cloudstack/pull/1253#issuecomment-387360970
There is an issue with existing environments, which may be using
dvsportgroups. If portgroup has more than (say) 8 ports in use already then a
error such as:
`Cannot set number of ports to 10 because at least 11 out of 18 ports are
still in use`
will be thrown when creating a VM on said switch and the VM will fail to be
deployed.
Setting ALL dvsportgroups to use a sufficiently high number will be
expensive in large environments.
Code needs to set number of ports to slightly higher than the number of
ports in use, on a per portgroup basis.

> CloudStack has a global config paramter vmware.ports.per.dvportgroup for
> setting the number of ports per dvportgroup of Distributed Virtual Switch
> (DVS) and this takes effect when the zone is created.
> Auto expand/shrink features adjusts the ports per dvportgroup value
> dynamically from ESX 5.0 release. So, even if we set this global setting,
> auto expand will take effect and the value configured at cloudstack is not
> useful anymore.
