RackSwitch G8000: Application Guide
Distributed VM Groups
Distributed VM groups allow configuration profiles to be synchronized between the
G8000 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 G8000 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 170 for
more information.
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).
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 174 .
Once configured, the VM profile may be assigned to a distributed VM group as
shown in the following section.
Initializing a Distributed VM Group
Note: A VM profile is required before a distributed VM group may be configured.
See “VM Profiles” on page 168 for details.
Once a VM profile is available, a distributed VM group may be initialized using the
following configuration command:
RS G8000(config)#
virt vmprofile
<profile name>
RS G8000(config)#
virt vmprofile edit
<profile name>
?
vlan
<VLAN number>
shaping
<average bandwidth> <burst size> <peak>
RS G8000(config)#
virt vmgroup
<VM group number>
profile
<VM profile name>
