Subject Re: Working with clouds on multiple ESX hosts

I forgot to reply all so the group see's my answer:
i see. so for trunk2, you want to trunk your zone vlans (that were defined
in cloudstack for the advanced,guest networks) to it. you should see the
portgroup being created on vswitch1, for the guest network. if that vlan is
present on all hosts, and switchports, you should be good to go.
