Integrity VM and Guest VLAN tagging support

[Chris Devlin]

I'm running IVM 4.10 on 11.31 host.

I've configured VLAN tagged interface(VLAN5000) on the host which is working as expected.

I tried to create a vswitch using the above interface and get the error:

hpvmnet: ERROR (host): The nic identifier 5000 is unsupported - cannot use a VLAN or an IPoIB nic for a vswitch.
hpvmnet: Unable to create the vswitch.
hpvmnet: Unable to continue.

From reading a chapter in the install guide, It looks to me like VLan tagging is not supported from the guest:

If the guest has to communicate with the VM Host or outside the VM Host over a VLAN,
additional configuration is necessary. For communication to the VM host, configure a VLAN
interface on the VM host interface for that vswitch. This VLAN interface should have the same
VLAN ID as the guest port. For information about configuring VLANs on the VM Host, see the
Using HP-UX VLANs manual. Do not use the hpvmnet command to create a virtual switch that
is associated with a VLAN port on the VM Host (that is, a LAN created with lanadmin -V).
This “nested VLAN” configuration is not supported.
Frames arriving at the vswitch from a guest can be “tagged” by the vswitch. Tagging consists of
inserting the VLAN ID information into the MAC header before forwarding the frame on. Tagged
frames destined for a guest are always stripped of the tag information in the frame before being
forwarded. For Integrity VM, only tag-unaware guests are supported.

Any information around this would be greatly appreciated.

Thanks

I am running into the same issue. Have you found a way around this?

Thanks.

It's resolved in IVM 4.2 as Guest VLAN tagging is supported, but I've not tested it myself as yet.

Thanks Chris.

Just upgraded from 4.1 to 4.3 and VLAN tagging now works for the guest.
