Distributed VM Groups
Distributed VM groups allow configuration profiles to be synchronized between the G8124 and
associated hypervisors and VEs. This allows VE configuration to be centralized, and provides for
more reliable VE migration across hypervisors.
Using distributed VM groups requires a virtualization management server. The management server
acts as a central point of access to configure and maintain multiple hypervisors and their VEs (VMs,
virtual switches, and so on).
The G8124 must connect to a virtualization management server before distributed VM groups can
be used. The switch uses this connection to collect configuration information about associated VEs,
and can also automatically push configuration profiles to the virtualization management server,
which in turn configures the hypervisors and VEs. See “Virtualization Management Servers” on
page 172 for more information.
Note – Distributed VM groups are not supported simultaneously on the same ports as vNICs (see
“Virtual NICs” on page 153).
VM Profiles
VM profiles are required for configuring distributed VM groups. They are not used with local VM
groups. A VM profile defines the VLAN and virtual switch bandwidth shaping characteristics for
the distributed VM group. The switch distributes these settings to the virtualization management
server, which in turn distributes them to the appropriate hypervisors for VE members associated
with the group.
Creating VM profiles is a two part process. First, the VM profile is created as shown in the
following command on the switch:
Next, the profile must be edited and configured using the following configuration commands:
For virtual switch bandwidth shaping parameters, average and peak bandwidth are specified in
kilobits per second (a value of 1000 represents 1 Mbps). Burst size is specified in kilobytes (a value
of 1000 represents 1 MB).
