Two advanced bash tricks

Well, tricks is not the right word to describe advanced shell scripting usage, however, it does make some sense. These two topics are relevant to Bash version 4.0 and above, which is common for all modern-enough Linux distributions. Yours probably.
These ‘tricks’ are for advanced Bash scripting, and will assume you know how to handle the other advanced Bash topics. I will not instruct the basics here.
Trick #1 – redirected variable
What it means is the following.

How fast is Xen on ARM, really?

With Xen on ARM getting out of the early preview phase and becoming more mature, it is time to run a few benchmarks to check that the design choices paid out, the architecture is sound and the code base is solid. It is time to find out how much is the overhead introduced by Xen on ARM and how it compares with Xen and other hypervisors on x86.

Two Real Node (Controller+Compute) IceHouse Neutron OVS&GRE Cluster on Fedora 20

Two boxes  have been setup , each one having 2  NICs (p37p1,p4p1) for Controller && Compute Nodes setup. Before running `packstack –answer-file= TwoRealNodeOVS&GRE.txt` SELINUX set to permissive on both nodes.Both p4p1’s assigned IPs and set to promiscuous mode (192.168.0.127, 192.168.0.137 ). Services firewalld and NetworkManager disabled, IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface p37p1 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).

Welcoming Cavium as latest Xen Project Advisory Board member

Cavium-Logo-TransparentWe’re excited to welcome Cavium as our newest Xen Project Advisory Board member today. Since becoming a Linux Foundation Collaborative Project with eleven founding members, we announced five new members, including ARM, NetApp, Rackspace and Verizon Terremark.

Two Node (Controller+Compute) IceHouse Neutron OVS&GRE Cluster on Fedora 20

Two KVMs have been created , each one having 2 virtual NICs (eth0,eth1) for Controller && Compute Nodes setup. Before running `packstack –answer-file=twoNode-answer.txt` SELINUX set to permissive on both nodes. Both eth1’s assigned IPs from GRE Libvirts subnet before installation and set to promiscuous mode (192.168.122.127, 192.168.122.137 ). Packstack bind to public IP – eth0  192.169.142.127 , Compute Node 192.169.142.137

HowTo: Xen4CentOS

Using CentOS 6 as the Control Domain for the Xen Project Hypervisor

Lots of hosting companies and other service providers settled on combination of the Xen Project Hypervisor and CentOS as a platform for their virtualization needs.  Unfortunately, CentOS 6 brings with it the same kernel as RHEL 6 — a kernel which lacks support for the Xen Project Hypervisor.
