VLAN Tagging (VST) and Native VLAN on same vswitch

[NuRD]

I'm trying to figure out if its possible to turn on VLAN tagging for a vswitch if our virtual machines currently reside in vlan 1 (native vlan) on our cisco switches. I'm not sure why it was setup this way, but changing it is not an option at this time.

Ultimately what I'm trying to accomplish is bringing up a group of servers that are on a different VLAN, but under the same vswitch. I'm assuming VST is what I need, but I'm not sure if I can simply specificy vlan 1, as vlan 1 is untagged on the cisco switches and my understanding is that VST requires it to be tagged.

Your assistance is greatly appreciated.

With the vSwitch connected to a trunk port on the physical switch, create the port groups you need and only configure the then VLAN-ID for the port groups which do not use the native VLAN. See e.g. http://kb.vmware.com/kb/1004074

Thanks! That's exactly what I needed.
