windows 2008 clustering and vmotion

I currently have 2 vms 2008 running mscs on the same esx machine using rdm. How do I do vmotion to migration these vms to a different host?

you cannot vmotion MSCS clusters (which is why you using run a node on each host.

Read page 11 for limitations.

I see that. I am confused about the 2 physical NIC requirment.

I already have 3 NICs (trunks) assigned to vms. Can I just use this as the public nic?

Then maybe throw in a cheap gig switch for the private nic for all esx hosts to connect to?

I am confused about the 2 physical NIC requirment.

If you mean the NIC requirement for a MSCS or Failover Cluster these are simple vNIC, you must give a vNIC for the LAN/public traffic and build a portgroup for the private traffic to use another vNIC.

it says to dedicate 2 physics NICS for mscs clustering across 2 ESX hosts.

I am current doing it on one host but I want to move one vm to another host since I cannot vmotion.

My question is can I put the public vnic of the 2008 clustered vms on the same port group as my other vms?

and then

setup a physical nic and portgroup for the private nic on each esx host with the physical nic connected to an isolated switch

how do I do this?

You do not really 2 pNIC for each node. You ony need 2 vNIC.

My question is can I put the public vnic of the 2008 clustered vms on the same port group as my other vms?

Yes, as written before.

Just use the same network for other VM.

setup a physical nic and portgroup for the private nic on each esx host with the physical nic connected to an isolated switch

how do I do this?

You do not really a isolated switch, but if you have a spare pNIC you can create a new vSwitch ad use an external switch to connect them (this is a way to implement an isolated switch across two or more ESX).

But you can simple create a new VM portgroup on the same vSwitch for other VM.

if I have a spare pNIC on each esx host, and create a portgroup for the heartbeat network, do I have to create a private vlan on the switch for this?

No.

Just create a new vSwitch with this pNIC and the "private" VM portgroup.

Yes, but you still need a pNIC mapping also with dvswitches.

And you need the Enterprise Plus license.

You can leave on none.
