OpenVZ Project Pushes Technology Boundaries Combines Different Types of Open Source Virtualization

HERNDON, Va., November 28, 2007 — The OpenVZ project shows what is possible using its open source virtualization software in combination with virtual machine open source Xen software — effectively creating many virtual servers to improve utilization of the physical server.

A software download available at the OpenVZ website, http://openvz.org/download/kernel/rhel5, enables users to divide one physical server into virtual servers using Xen software, and then creating OpenVZ virtual environments inside those virtual machines.

The software download is based on the RHEL5 Xen kernel with builds available for both x86 and x86_64 platforms. The software can run on the Xen hypervisor in both Dom0 and DomU.

"We wanted to show people what is possible with the low overhead of our operating system (OS) virtualization open source OpenVZ software," said Kir Kolyshkin, manager of the OpenVZ project. "This is a marriage of complementary technologies that blends the flexibility of virtual machine technology, which is capable of running different operating systems, along with the efficiency of OS virtualization, which can run several times more virtual servers as compared with other virtualization technologies."

"This combination of open source virtualization technologies provides users with flexibility of running one or more guest operating systems, while also realizing high performance through low overhead," said Tom Schwaller, an expert in Linux, open source and virtualization technologies based in Germany. "We're seeing virtualization technologies maturing as we really understand what is possible."

OpenVZ Virtualization Keeps E-mail Filtering Service Up and Running

JunkEmailFilter.com Uses Operating System Virtualization to Manage its Network of Servers

HERNDON, Va., November 15, 2007 – JunkEmailFilter.com works in the dangerous area of sorting through e-mail to filter out viruses and junk e-mails known as "spam," so that its clients receive only the e-mails they want to see. For higher levels of control and security, it uses open source virtualization software, known as OpenVZ.

"In our business, it's a necessity to have redundant systems in different locations in case bad things happen," says Marc Perkel, support manager at JunkEmailFilter.com. "People are dependent on us to get their e-mail through, so we cannot afford downtime."

The company has set up virtual servers with OpenVZ operating system server virtualization software and maintains backups so that, if necessary, a virtual server can be restored on another physical server and started up immediately.

There are four OpenVZ virtual servers on each of four physical servers that run e-mail server software, MySQL and SpamAssassin with virtual servers as large as 4 gigabytes.

"OpenVZ has almost no overhead, so we are giving up almost nothing in terms of performance to run virtual servers," says Perkel. "In our experience, OpenVZ has been compatible with most everything we run so it's one of those 'just works' solutions."

"We run different software programs in different virtual servers," says Perkel. "That way, one application isn't compromised if another application has an issue."

"With OpenVZ, we can also limit applications to specified amounts of memory and processing power, which allows us to tune our resources very precisely. If necessary, those can be adjusted on the fly," says Perkel.

The company has used OpenVZ software to create templates for different virtual servers, such as its VoIP phone system and SpamAssassin servers that process e-mail. Each virtual server is deployed on a physical server independent of others, which enables virtual servers to be moved among physical servers to balance workloads.

About JunkEmailFilter.com

E-mail filtering is easy to set up and doesn't require users to change their existing e-mail server. Instead of e-mail coming from the Internet directly to the user's e-mail server, it goes to spam filtering e-mail servers. There, it is stripped of viruses and spam and within seconds is passed on to the user's existing e-mail server. JunkEmailFilter.com is based in San Bruno, California.

About OpenVZ

OpenVZ is operating system server virtualization software technology, built on Linux, which creates multiple isolated, secure virtual environments on a single physical server – enabling greater server utilization and superior availability with fewer performance penalties. The virtual servers ensure that applications do not conflict and can be re-booted independently.

With the power of today's processors, hardware is often under utilized. With virtualization technology, the server can effectively be split into many small ones, each running its tasks so that the whole server is utilized more efficiently

OpenVZ software can be used to help consolidate servers and increase server utilization rates, or for creating "sandboxes" for test and development, or when sharing resources so that every user can have root access while being kept isolated from each other.

The OpenVZ software comes with user tools that help automate management of virtual servers. With its unique architecture that uses a single operating system instance, the virtual servers perform and execute like independent servers with their own memory, configuration files, users and applications. Each can be re-booted independently. Using template-based application deployment provides a simple way to get new virtual servers up and running in minutes and OpenVZ can run several times more virtual servers per CPU than other virtualization technologies. Also, the OpenVZ project maintains a blog site discussing virtualization technology, which can be accessed here, http://blog.openvz.org.
