The Docker exploit and the security of containers

We normally only cover news and information directly related to Xen in this channel, but we thought it might be useful to briefly expand our scope a bit to mention the recent discussion about the Docker security exploit.

What’s the news?

Well to begin with, a few weeks ago Docker 1.0 was released, just in time for DockerCon.

RDO IceHouse Setup Two Node (Controller+Compute) Neutron ML2&OVS&VLAN 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= TwoNodeML2&OVS&VLAN.txt` SELINUX set to permissive on both nodes. Both eth1’s assigned IPs from VLAN 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

Release management: Risk, intuition, and freeze exceptions

I’ve been release coordinator for Xen’s 4.3 and 4.4 releases. For the 4.5 release, I’ve handed this role off to Konrad Wilk, from Oracle. In this blog, I try to capture some of my thoughts and experience about one aspect of release management: deciding what patches to accept during a freeze.

I have three goals when doing release management:

Developer Summit Line-up Announced

I am pleased to announce the schedule of the Xen Project Developer Summit. The event will take place in Chicago on August 18-19, 2014.

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 ).
