0022-rh1112020-crash-reading-bridge-sysctl.patch
relevant patch for MTU issue is 0023-rh1093231-mtu-fix.patch
As to the creation of the image in question, I cannot find the
process on the centos git, so, answering the question of:
were updates applied?
will need to await KB ...
Yeah, I expect KB will document kickstart and the build process somewhere.
In the meantime I've inspected
CentOS-7-x86_64-GenericCloud-20140826_02.qcow2 and it contains
unpatched NetworkManager-0.9.9.1-13.git20140326.4dba720.el7
Cheers,
