Perform the following steps on each server participating in the Contrail Fabric after running fab upgrade_kernel_all:

1.	Open the /etc/default/grub file and do the following change:

to

GRUB_DEFAULT='Advanced options for Ubuntu>Ubuntu, with Linux 3.13.0-40-generic’
2.	Enter the following:
root@test:~# update-grub
root@test:~# reboot
3.	Once the servers are back up and running, you can use the uname -a command to check the kernel version that the operating system has booted from.
