Vlan's and Virtual Servers

So my sysadmin told me there's not enough usable IP's in VLAN 209 for about 40 virtual servers. The host machine is in Vlan 209. Vlan 210 is empty, so he wants me to put Vlan 210 on the same access port so he can have more Ip's to use.

If I put another Vlan on the same port, wouldn't that make it a trunk port? Is there a better way to accomplish this goal? I'm still fairly new to networking.
