I've been playing arround with ESXi 3,5 and fortunatelly it is a test enviroment but......I guess it could happened at any time to anybody that is anybody unexperienced like myself.

Here is what happened:

I have a host machine running ESXi 3.5 with 1 NIC

That of course creates a default vswitch0. Then I created an isolated vswitch just to see how it works. Called it internal. LOL then I went to a properties of that vswitch1 and added that only NIC that my physical box have.

After that my client can no longer access a host and therefore manage ESXi server. I accessed a console (unsupported and using esxcfg-vswitch -l I verified that I do have 2 vswitches 0 and 1.

Assuming that somehow my only NIC works now with two vswitches (and that prevents client from accessing host) I removed vswitch1 but still can not access (nor ping) host

esxcfg-vswitch -l command gives a following output:

vSwitch0 64ports used ports(2) configured ports (64) MTU 1500 Uplinks none

VM Network 0 (VLAN ID) 0 (used ports)

Management Network 0 (VLAN ID) 1 (used ports)

My conclusion is somehow I lost (removed or....) from vswitch0. Since I don't have a redundant service console access I would really appreciate any help since like I said before it may happen in a real life scenario at any moment.

Cheers,

Konrad
