Summary
You followed the instructions in the SSFE 2.1 Installation Guide on how to setup SSFE on a Hyper-V environment. However, after installation you experience SSFE 2.1 server performance issues such as slow network and server response.
Details
To resolve the issue, the Linux Kernel of the SSFE server must be upgraded to version 3.8.0. Follow the procedure below on Appliance1 and Appliance2 if SSFE is deployed in a High-Availability setup.
- Log in to the SSFE server shell or command-line interface (CLI).
- Create a temporary directory to store the new kernel using the commands:
# mkdir /tmp/new-kernel
# cd /tmp/new-kernel - Download the Linux image to upgrade the kernel using the command:
# wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-lts-raring/linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.deb
- After the file has been downloaded completely, verify the file checksum using the command:
# sha1sum linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.debMake sure the value of sha1 is a0bfd9da477fc956600ea754c2124042ae62eea9.
- Install the kernel upgrade by running the command:
# sudo dpkg -i linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.deb
- Once the upgrade process is done, reboot the server by running the command:
# sudo reboot
- After the reboot, verify that the kernel has been upgraded to 3.8.0 using the command:
# uname –a
