G8264 Application Guide for ENOS 8.4
Distributed VM groups allow configuration profiles to be synchronized between
the G8264 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 G8264 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
more information.
Note: Distributed VM groups are not supported simultaneously on the same ports
as vNICs (see Chapter
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:
virt vmprofile
RS G8264(config)#
Next, the profile must be edited and configured using the following configuration
commands:
RS G8264(config)# virt vmprofile edit <profile name> ?
eshaping <average bandwidth> <burst size> <peak>
shaping <average bandwidth> <burst size> <peak>
vlan <VLAN number>
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). Eshaping (egress shaping)
is used for distributed virtual switch.
Note: The bandwidth shaping parameters in the VM profile are used by the
hypervisor virtual switch software. To set bandwidth policies for individual VEs,
see "VM Policy Bandwidth Control" on page
Once configured, the VM profile may be assigned to a distributed VM group as
shown in the following section.
