dhcp-option=26,1454
It forces any new created VM's ( Ubuntu,F20) MTU to be set to 1454
Deployed CentOS 7 VM had MTU 1500 what was verified via load
without ssh-keypair wit post creation script assigning password to
user "centos". I believe that current image would have problems on
GRE Systems.
This issue was fixed in NetworkManager-0.9.9.1-25.git20140326.4dba720.el7_0
which was imported in git.c.o:
https://git.centos.org/commit/rpms!NetworkManager/69d374bc89058971025b19e...
Karanbir, is image build not including updates?
Cheers,
