Tomorrow, Scott and I will be attending the VMware Users Summit 2009 at the Renaissance Charlotte Suites Hotel in Charlotte, NC. This is a free event, so if you’re out and about with nothing else to do, come by and join the rest of the VMware nerds. Here is some information on the VMware Summit in Charlotte: Carolina VMware User Summit (CVUS) 2009 will be even more exciting this year! The summit will feature some of the industryâ€™s very best virtualization experts from across the globe. If you enjoyed last year’s Carolina VMware Users Summit, you will not want to miss out on Carolina VMware Users Summit 2009. These speakers and many more will be on-hand to guide us through our everyday challenges and give us a peek into what may be to come.
This is a handy backup script that will once a week perform a vzdump operation on your HN, thus dumping an imaged copy of all of your virtual machines, then uploading them all to the FTP server of your choice using ncftpput.

This awesome article shows how to setup an OpenVZ high availability (HA) cluster using the data replication software DRBD and the cluster manager Heartbeat. In this example the two machines building the cluster run on CentOS 4.3.
As we get further into developing the Piranha Method site, we plan to also work on deploying a site for Hostmaster Flex to offer our hosting services for the OpenVZ cluster that we have set up.
The OpenVZ project is an open source community project supported by OpenVZand is intended to provide access to the code and ultimately for the open source community to test, develop and further the OS virtualization effort. –
We are currently running a Linux High-Availability hosting cluster built on a custom OpenVZ kernel for server virtualization on the Debian etch Linux distribution along with RAID-1 server using DRBD. In the future we plan to add more servers to the cluster and load balance the cluster load between them, we are currently planning to deploy the necessary fibre channel gigabit technology for each server in order for this to be feasible.
We have been running our OpenVZ cluster for about two years now in a production environment and have only had some minor problems with our 3ware Escalade RAID controllers Linux drivers. This was because we were previously running our cluster on the CentOS 4.4 (RedHat) distribution and apparently our hardware combination, along with the use of OpenVZ technology uncovered a bug in the 3ware Linux drivers.
Overall, I have had nothing but a great experience with OpenVZ, my only wishÂ (if someone is so inspired) would be a nice web-based GUI for virtual server management and migration. I have found a few OpenVZ managers out there, but none that seem complete or even that seem to function correctly.
