i'd added it to my opensuse guests' configs a long while back to solve "some problem" -- honestly, too long ago to tell you why ... other than it still works. for opensuse guests, anyway.
Does the domU boot progress if this setting is removed?
nope. still hangs at: ... Initalizing network drop monitor service Write protecting the kernel read-only data: 483k

Possible. I know next to nothing about Centos' images. The boot img is a netinstall disk. Perhaps a bit "short" on it's capabilities ... aria2c is dl'ing the full DVD to test as I type here ...
