VM Profiles

Initializing a Distributed VM Group

© Copyright Lenovo 2015
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:
CN4093(config)# virt vmprofile <profile name>
Next, the profile must be edited and configured using the following configuration
commands:
CN4093(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).
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.
Note: A VM profile is required before a distributed VM group may be configured.
See "VM Profiles" on page 245
Once a VM profile is available, a distributed VM group may be initialized using the
following configuration command:
CN4093(config)# virt vmgroup <VM group number> profile <VM profile name>
Only one VM profile can be assigned to a given distributed VM group. To change
the VM profile, the old one must first be removed.
CN4093(config)# no virt vmgroup <VM group number> profile
Note: The VM profile can be added only to an empty VM group (one that has no
VLAN, VMs, or port members). Any VM group number currently configured for a
local VM group (see "Local VM Groups" on page
must be deleted before it can be used for a distributed VM group.
