Citrix Hypervisor

The free version is a boon for small businesses that want to have a hypervisor but not the headaches of using something that requires licensing. It is more than adequate to compete with the lesser versions of Hyper-V or VMware. Any small business that wants to lessen its hardware footprint could benefit from this product. If you are a medium or large business it is also a nice addition to the cupboard if you already use other Citrix products and are familiar with the Citrix support process. Shops that are fully committed to VMWare or MS Hyper-V should probably avoid this as it would just act to dilute your system and add unneeded complexity. Citrix Hypervisor is not most common Hardware Hypervisor on the market but it is more than competent for most Enterprise Deployments.

Oracle VM VirtualBox

Being able to build VM's to test different applications on Virtual machines in order to validate functionality without the worry of compromising a real system and having to start over is one of the greatest strengths of using an application like VirtualBox, and it does this well. The many options to create a VM of differing operating systems and functionality [make it] very simple and easy to do with this application.

Pros

Citrix Hypervisor

  • Resource Monitoring is a good and I am able to monitor my entire infrastructure whether I'm using my iPhone remotely or while on any company-issued laptop to ensure our services run at peak efficiency.
  • CLI - the command line is not hard to use. It can take a little time to get used to the commands but once you have them down managing the environment from the GUI or CLI is pretty easy.
  • Backups are very easy to start and manage with XenCenter or XoA. Keeping business DR scenarios achievable.

Oracle VM VirtualBox

  • It is simple to install - there is no advanced knowledge required to begin building virtual computers
  • It is easy to use - adding new virtual machines is simple with wizard-based deployment
  • It enables easy portability - moving virtual machines from one host to another is straight-forward and simple
  • It is free

Cons

Citrix Hypervisor

  • Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
  • The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
  • Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
  • Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.

  • I have had issues in the past when it has come to resizing VM disk storage. The issue is entirely detailed here: https://www.virtualbox.org/ticket/9103 -- the problem was caused because of having existing snapshots (which error message output was not detailing). I haven't had to deal with the issue due to my dynamic disk sizes not being small from the start anymore (this is mostly an issue for my Windows VMs where the base disk may need significant size for the OS). It looks like, for a resize, that a merge of all snapshots has to occur first -- one user on that list details a workaround to maintain snapshots by cloning the VM. (Note: 5.2 was just released a few weeks ago, and looks like it should prevent the problem happening in the future by properly informing users that it isn't possible with snapshots).
  • Certain scenarios, like resizing disks, required dropping into a terminal as there were no options to previously do so via the GUI. According to some recent posts, I've seen that v5.2 has added disk management stuff like that to the GUI (or will be adding it). I'm comfortable with dropping into the terminal, but in a teaching scenario or when evaluating the learnability of the tools, it complicates things.

With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used

XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

Easy and quick to use. Runs at sufficient speed even with 5/6 VMs running, and can handle a bridged network with ease. Easy to disassociate from the host to ensure the environment built within VB is quarantined should anything happen, meaning no risk to physical hardware.Quick to pick up. Quick to add new machines. Cloning feature very quick and comprehensive. I've never had a VM crash or freeze.

It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.

Alternatives Considered

Citrix Hypervisor

VMware seems to be the standard and is more widely accepted. However, Citrix Hypervisor, is easily learned and cheaper. We have also used VirtualBox to offer up ideas for other free products. VirtualBox seems to be easier for end users who just want simple VMs and not necessarily entire environments. Citrix is good for environment virtualization.

There are a lot of Pro's to using VmWare in an enterprise environment like a management console, deployment via templates and so on. But in terms of ROI, extreme ease of use, availability and customization VirtualBox wins the race for personal use but faces extreme competition in enterprises. Again, personally I would recommend VirtualBox to anyone out there looking for a good, friendly and free host virtualization application.

The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

Return on Investment

Citrix Hypervisor

  • Xenserver is easy to learn. We paid for support only for installation and deployment in the first three years, and now our team has the knowledge to solve most problems.
  • Low CAPEX if you have a team that uses open source software day by day.
  • But paid support is necessary to solve critical problems. The open source community is not enough. Actually, we have difficulty solving some bugs without paying for support.
  • Medium OPEX if you have a team that uses open source software day by day.
Stenio Pereira Filho | TrustRadius Reviewer

Oracle VM VirtualBox

  • Minimal-to-no support needed from the DevOps team.
  • Provides a direct and an easy way to access multiple VMs inside the same machines which enables performing various testing and QA tasks without the need to switch hardware.
  • Automatic provisioning using tools (esp. Vagrant) which enables developing a base image once, and allows for exporting/importing anywhere across the developers team.
  • Very cost-effective (no fees or monthly subscriptions).
