Xen Project Reviews & Product Details

Possibility to virtualize Hardware and Software with a great performance for our virtual machines.

The types of virtualization, traditional, emulation, and complete that simulates the base hardware.

Virtualization at the OS level is shared with the Kernel and the architecture

It has a high performance to virtualize

No need special drivers.

The Administration Console for configuration and destruction creation is very intuitive if you are familiar with GNU / Linux systems

Standalone Hypervisor

Possibility of agendar

Make backup

The loading balaceo

the minimum requirements to install the Xen and the debian that is part of the requirements and guarantee a high performance at the time of virtualization because there is no layer of emulation between the Hypervisor and the virtualized systems.

The installation process is required to install previously Devian which is easily installed and on it we can install the Xen Project.

The configuration process is very simple and has an open source version where the community actively collaborates in functionalities tips or errors that arise.

The code that interacts with XEn is written in Phynton and makes it easy to correct errors.

One point in favor is the possibility of using it on Amazon Review collected by and hosted on G2.com.

There are not many cases of reported bruises and when we are presented with an error, the log does not show us that it is traced with an exception not captured.

The OpenSource version is very alpha than the final version.

If it is required to make many inputs or outputs or the VirtlO is used to connect the virtual hard disks, the performance of Xen is not the best. Review collected by and hosted on G2.com.

Xen was one of the first reliable hypervisors to be released. It is & was so powerful, that any time someone said "virtual server", you would think Xen, and it is currently the number one & most used virtualization platform in the cloud, which says a lot. Since Xen is separate from the OS & goes even further by separating out each component, it provides exceptional security, performance, and full OS neutrality, letting you run any OS you want in a virtual environment. Xen has many cutting edge features, and is always adding more, while making sure it is one of the most stable platforms available. Review collected by and hosted on G2.com.

Xen does not offer a wide variety of easy to use management tools, and you should expect the same level of management tools as most other open-source software. The command line also requires quite a bit of training, though command syntax and how-to's are all over the internet. Review collected by and hosted on G2.com.

The hypervisor is lightweight where many virtual machine instances can be fired up simultaneously (depending on the amount of resources allocated towards each, along with what's available from the actual host too). It allows each virtual machine to have dedicated resources, different configurations and operating systems to be ran natively when virtualization technology is enabled for the CPU in the BIOS.

Isolation from the other machines is nice. Review collected by and hosted on G2.com.

In the past, there's been security vulnerabilities especially with the guest hosts where they're able to gain root access to the main host. I know many of those have been fixed since, but it's one thing that has to be constantly monitored for 0 day exploits.

Other instances still have the ability to take down a complete virtual server if they're being targeted or getting way too much traffic. Review collected by and hosted on G2.com.

We moved from VMware to Xen and haven't looked back. The base OS has everything we need, support for migrating virtual machines from one host to another, snapshots, High Availability. We run a mix of OS on our hypervisors, from Windows to Linux and FreeBSD. They all work great. It's open source and support is widely available. Review collected by and hosted on G2.com.

I don't like that XenCenter is windows only. There are things that allow you to manage Xen from Linux or OS X but I still manage to find myself booting up a VM to do any real Xen management. Though, there are some web interfaces that are quite lovely and provide about 80% of what you would want to do. Development can be slow, especially in today's world. But version 7 was just released so that's nice.

Upgrading from an old version to the new major release basically requires a fresh install which is bonkers to me. Review collected by and hosted on G2.com.

There is literally no reason NOT to use Xen. It just works... and it works exceptionally well! It's so easy to con figure, and it's stable. It's easy to set it and forget it. Instances can remain up for an indefinite amount of time, and run efficiently. Review collected by and hosted on G2.com.

There's really nothing to dislike about Xen. As I previously mentioned, it does its job well. Review collected by and hosted on G2.com.
