Using tar rather than dd would likely be faster if there's any
significant amount of free space on the source disk. dd will copy all
those unused blocks, while tar will copy just the Useful Data.
The network interface config files
(/etc/sysconfig/network-scripts/ifcfg-*) contain the interface MAC
address. You'll probably need to modify that. It may be easiest to set
up a one-time boot script so this can be set on the destination (B)
machine the first time it boots.
If you use selinux, you may want to touch .autorelabel in the B root
file system so the contexts will get set properly when it boots.
