Red Hat Bugzilla – Bug 840519
Wrong statement about networking requirements
Last modified: 2014-03-25 03:11:22 EDT
Description of problem:
chapter 10.1 states that every logical network will require a separate NIC, and that the amount og logical networks is limited by the amount of NICs the hosts have.
This is wrong because we can have as many logical networks as we have vlans defined, even on a single physical NIC.
The number of logical networks that can be defined and implemented in a Red Hat Enterprise Virtualization environment is limited by the number of network interfaces present on the virtualization hosts in the environment. Each logical network needs at least one physical device to support it. Because a logical network must be implemented for each host in a cluster for the logical network to be operational, the number of logical networks that can be implemented in a given cluster is limited by the host in a cluster with the fewest NICs.
The previous statement:
Each logical network must be associated with a cabled, active network device. The network device that supports each logical network can be physical, a NIC or logical, like a bond device or virtual NIC(VNIC).
is also wrong - when we discuss the livel of Hosts and not VMs, vNICs are irrelevant. VLAN interfaces on the other hand are not mentioned at all
Version-Release number of selected component (if applicable):
Hey Tim, can you check if the Technical Reference or Admin Guides contain the same statement and clone as needed?
