Installation guide

scri pts/i fcfg -name_of_bridge file to turn STP on with a 0 second
delay:
STP=on
DELAY=0
After changing the configuration file, restart the bridge device:
/sbin/ifdown name_of_bridge
/sbin/ifup name_of_bridge
Note
If name_of_bridge is not the root bridge in the network, that
bridge's delay will eventually reset to the delay time configured for
the root bridge. In this case, the only solution is to disable STP
completely on name_of_bridge.

This message is only a problem if all four of the following conditions are
true:
The guest is using virt io network devices.
If so, the configuration file will contain mo d el type= ' vi rti o '
The host has the vho st-net module loaded.
This is true if l s /d ev/vho st-net does not return an empty result.
The guest is attempting to get an IP address from a DHCP server that
is running directly on the host.
The iptables version on the host is older than 1.4.10.
iptables 1.4.10 was the first version to add the l ibxt_C HEC KSUM
extension. This is the case if the following message appears in the
lib virt d logs:
warning: Could not add rule to fixup DHCP
response checksums on network default
warning: May need to update iptables package and
kernel to support CHECKSUM rule.
Important
Unless all of the other three conditions in this list are also true,
the above warning message can be disregarded, and is not
an indicator of any other problems.
