Comparison of Server Virtualization features of Product A and Product B
Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).
VMware vCenter Server is suited for pretty much any environment using virtual servers. It allows a centralized management view of the virtual servers and the physical servers that the virtual servers run on. There are so many things that VMware vCenter Server can do, including large Enterprise options that are cost-prohibitive for most organizations.
First and foremost, it provides a platform for us to virtualize our servers and it does it very well. Having the ability to spin up a new server from a template in a matter of seconds is amazing and saves precious time and resources.
VMware vCenter Server also provides the ability to view performance & statistical data that assists my team in balancing our host environment. Leveraging the vMotion functionality, we can quickly move VMs from one host to another for maintenance purposes, etc...
VMware vCenter Server also make it easy to add / modify hardware configurations within the VMs setup. Adding RAM, hard drive space, processor cores, etc...is as easy as it gets.
VMware vCenter Server makes it easy to backup and restore a VM from the console. You can quickly create a backup of any VM and store it during upgrades, etc...for easy roll backs.
I still am not happy with the web interface. While convenient in that I can access vCenter from anywhere I have a browser connection, It feels slower than the thick client and if I'm doing anything that takes longer than a few minutes, I'll always opt for the thick client.
We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using
It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.
I work with vCenter for 10+ years and i love it. I can find my way around and can help building and expanding the platform. It is easy to use and there are a lot good communities for the extra support when needed. Even the Homelab community is of great value.
VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.
Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.
The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).
vCenter is much more complete as a solution than other products that I have looked at and it works very well for our environment. vCenter is very easy to configure and does not have the unnecessary steps to set up and configure. Also, the different storage vendor support makes it easy to configure and maintain without having to use separate applications or consoles.
