Likelihood to Recommend It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.
Read full review It can be really helpful & useful if we are using Citrix Hypervisor with other provisioning tools. Here are some specific scenarios where Citrix Hypervisor (formerly Citrix XenServer) is well-suited: Server Consolidation, Virtual Desktops, Disaster Recovery, Development & Testing Environments. On the other hand, there are some scenarios where Citrix Hypervisor may be less appropriate: Small-scale Deployments, Highly Heterogeneous Environments, and Limited Virtualization Requirements.
Read full review Pros 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 Read full review Citrix hypervisor does price very well for small organizations. It is free. Since this product is open source it does not have any type of vendor lockdown issues. Allows live migration of VM's so you can keep systems up and running when changes are needed to the hardware in the background. The GUI management tools are quite easy to learn. Has Snapshot capability which is a great way to protect against malware as well as do risk-free upgrades. Read full review Cons 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. Read full review 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. Read full review Likelihood to Renew I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used
Read full review 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.
Read full review Usability 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.
Read full review 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.
Read full review Reliability and Availability Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.
Read full review 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.
Read full review Performance No issues, especially with the extensions addons.
Read full review 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.
Read full review Support Rating Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.
Read full review The staff I've worked with are very knowledgeable or able to get a very well articulated and capable support team member on the phone or helping them if necessary and they always want to ensure the best experience possible for you on the platform. The ability for the support team to reach out to hardware vendors for assistance is a nice plus too.
Read full review In-Person Training 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.
Read full review Online Training 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
Read full review Implementation Rating We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.
Read full review 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.
Read full review Alternatives Considered VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition
Read full review Feature for feature they are neck and neck. I have used Hyper-V 2012 and 2016,
VMware ESXi and XenServer evenly. XenServer is a fast install, good documentation, with enterprise features out the box that compare or exceed what VMWare offered with a higher cost of entry.
Read full review Scalability The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.
Read full review 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.
Read full review Return on Investment For personal use, there is no monetary investment, I am running 5 CentOS servers flawlessly in my home lab. Saves a ton of money in an enterprise environment by not having to purchase physical test servers. (Cost of Enterprise product is way lower vs Cost of standing up physical servers and/or cloud servers) Makes virtualization very easy and friendly for everyone for test instances. Read full review 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. Read full review ScreenShots
