Hi guys.
I read that RHEL will not support XEN in version 6 and it will support KVM. Does this mean we can't install XEN from RHEL repositories? Should we install it from source code? (8 Replies)

IFCFG-BRIDGE(5) Network configuration IFCFG-BRIDGE(5)
NAME
ifcfg-bridge - ethernet bridge interface configuration
SYNOPSIS
/etc/sysconfig/network/ifcfg-br*
CONFIGURATION
To setup a bridge interface you need a configuration file ifcfg-<interface-name> with the usual network settings. But you must add addi-
tional variables:
BRIDGE <yes|no>
This option must be set to 'yes' to identify this interface as a bridge interface.
BRIDGE_PORTS <interface1 interface2 ... interfaceN>
This variable contains a space-separated list of N interfaces which take part in the bridging.
OPTIONAL VARIABLES
BRIDGE_AGEINGTIME <time>
This option sets the ethernet address ageing time, in seconds. After <time> seconds of not having seen a frame coming from a certain
address, the bridge will delete that address from the forwarding database. Setting ageing time to zero makes all entries permanent.
BRIDGE_FORWARDDELAY <time>
Forwarding delay time is the time in seconds spent in each of the listening and learning states before the forwarding state is
entered. This delay is so that when a new bridge comes onto a busy network it looks at some traffic before participating.
BRIDGE_HELLOTIME <time>
Periodically, a hello packet is sent out by the root bridge and the designated bridges. Hello packets are used to communicate
information about the topology throughout the entire bridged local area network.
BRIDGE_MAXAGE <time>
If a another bridge in the spanning tree does not send out a hello packet for a long period of time, it is assumed to be dead. This
timeout can be set with this variable.
BRIDGE_PATHCOSTS <costs1 costs2 ... costsN>
This is a space-separated list of costs corresponding to the interfaces in BRIDGE_PORTS. Each interface in BRIDGE_PORTS could have
a different speed and this value is used when deciding which link to use. Faster interfaces should have lower costs.
BRIDGE_PORTPRIORITIES <prio1 prio2 ... prioN>
This is a space-separated list of priorities corresponding to the interfaces in BRIDGE_PORTS. The priority value is an unsigned
8-bit quantity (a number between 0 and 255), and has no dimension. This metric is used in the designated port and root port selec-
tion algorithms.
BRIDGE_PRIORITY <priority>
This option sets the bridge's priority to <priority>. The priority value is an unsigned 16-bit quantity (a number between 0 and
65535), and has no dimension. Lower priority values are 'better'. The bridge with the lowest priority will be elected 'root
bridge'.
BRIDGE_STP <on|off>
Multiple ethernet bridges can work together to create even larger networks of ethernets using the IEEE 802.1d spanning tree proto-
col. This protocol is used for finding the shortest path between two ethernets, and for eliminating loops from the topology. The
spanning tree protocol can also be turned off (for those situations where it just doesn't make sense, for example when this linux
box is the only bridge on the LAN, or when you know that there are no loops in the topology.)
EXAMPLE
Minimal example for a bridge interface on eth0 and eth1, the bridge interface itself is configured via dhcp:
ifcfg-br0
STARTMODE='auto'
BOOTPROTO='dhcp'
BRIDGE='yes'
BRIDGE_PORTS='eth0 eth1'
BRIDGE_PORTPRIORITIES='50 20'
