Configuring VMQ with SLB Teaming
When a Hyper-V server is installed on a system configured to use Smart Load
Balance and Failover (SLB) type teaming, you can enable virtual machine queue
(VMQ) to improve overall network performance. VMQ enables delivering packets
from an external virtual network directly to virtual machines defined in the SLB
team, eliminating the need to route these packets and, thereby, reducing
overhead.
To create a VMQ-capable SLB team:
1. Create an SLB team. If using the Teaming Wizard, when you select the SLB
team type, also select Enable HyperV Mode. If using Expert mode, enable
the property on the Create Team or Edit Team pages.
2. Follow these instructions to add the required registry entries in Windows:

3. For each team member on which you want to enable VMQ, modify the
following registry entry and configure a unique instance number (in the
following example, it is set to 0026):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E972-E325-11CE-BFC1-08002BE10318}\0026]

Device Drivers
Uninstall the Marvell BCM57xx and BCM57xxx device drivers from your system
only through the InstallShield wizard. Uninstalling the device drivers with Device
Manager or any other means may not provide a clean uninstall and may cause the
system to become unstable. For information on uninstalling Marvell BCM57xx and
BCM57xxx device drivers, see “Removing the Device Drivers” on page 100.
When removing the device drivers, QLogic Control Suite is also removed as well
as all other management applications.
Virtual machine queue (VMQ) Yes See “Configuring VMQ with SLB
Teaming” on page 296.
