VM guest communication

[Kehad Snydewel]

Hi Guruâ s,

Hardware specs:
1x BL870c
HA-OE 11iv3
VSE Software suite
2x VC-Enet
2x VC-FC

Customer LAN:
Nortel switch and all VC-Enet uplink port are tagged and in a 802.1q trunk

Customer requirements:
The VC-Enets must be configured to allow multiple networks over a shared uplink set which is configured successfully.
The ports should be tagged between the VC-Enet and Nortel switches.

Problem:

The VM guests cannot communicate out of the VM host. The VM guests can communicate with each other through the vswitch created. The same vswitch is connected to the VM host pNIC LAN1.

If we untag one of the VC-Enet uplink ports on the Nortel switch, define a new network (test) on the VCM and assign that test network to NIC 1 of BL870, we can ping the VM host port but not the VMs, if we use the shared uplink set with all the VLANs mapping to this uplink set, we cant ping NIC 1 and all VMs on the host.

we isolated the customer network by installing a single procurve switch and by doing this we were able to communicate between the Vm guests and VM Host.

Please give us some info on how to setup the VM guest to communicate outside the VM host when using customer Nortel switches.

If you want to use more than one link together(trunk) then you need to configure HP APA with "Link Aggregate". Then you need to implement VLAN on virtual switches, i cant see the such configurations on the docs you sent.

I have 4 vswitches configured and each one connects to a pNIC of the BL870. So i am not using Link aggregation on the VM host. how can I tag the pNIC connecting the the vswitch? is this possible on IVM?

[Torsten.]

Link aggregation must be done on the host (APA - is already installed, but not configured), not on the guest.

Bind some pNIC to an APA interface and assign this to a guest (e.g. lan900).

If you want to use ttrunking then you have to implement apa link aggregate on the VM host. If you will not use link aggregate then on the switch side remove trunk config. You can configure VLANs on both APA and normal interfaces.For VLAN config look at:
