KVM Room for Improvement

Georges ESSOMBA - PeerSpot reviewer
Business Engineer and Consultant at All-Tech

One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy. For this kind of task, you have to get behind the command-line to set it, and this process isn't easy for a newcomer. However, if you have planned your virtualization project well and you know exactly how much RAM and storage space you will need for each different VM, you can simply set it and forget it, because everything you set is permanent.

Another improvement I would like to see is better functionality when it comes to making snapshots automatically while the VM is still running. For example, when a VM is running and you want to back it up, occasionally the VM backup that you obtain is not usable. Thus, I would propose that in the next edition of KVM there should be better "hot" backup features (as opposed to "cold" backups which are performed when the VM is powered down).

From my skill set and what I'm capable of, I wouldn't know how to say what could be improved as it works exceptionally well. I know that things can always be improved. 

One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines. That's one thing that's a little bit confusing. That's more systems administration, in general. If they would make it a little easier to do, then you wouldn't have to have so much systems admin knowledge in order to use one feature.

I tried to follow the information provided, however, then the partitions were added, the logical drive, and it didn't actually end up being initialized correctly. I'm pretty sure it's due to my own error, and not using it correctly. However, if they would have been clear on how to do it, or if they could even build a command that literally executes the necessary commands for you, just by typing, or using the virtual manager, that would have been helpful.

I've only used the solution for a short period of time, so maybe it's there, however, I'd like it if maybe they could combine some network manager type item in there to be able to bridge connections a little easier. Then, you wouldn't have to do it as a separate task. Perhaps their existing network management already includes that. I'm not sure.

This solution is lacking in features such as management and integration.

  • This solution needs better integration with desktop virtualization.
  • Better integration with storage solutions is needed.
  • Business continuity features need to be added.
  • The live migration needs to be improved.
  • You cannot run this application in a data center using only the GUI, so you have to have some knowledge with Linux in order to best manage it.
  • Better network management software is needed.
  • Features like vSAN are not available on KVM.
  • Integration with Kubernetes would be an improvement.

Generally, this solution should be made easier to use. Many customers don't have enough experience with Linux or a deep understanding of operating systems, and they just want to use the product. This together with a lack of features has led customers to choose VMware.

Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view.

Their support for snapshot and revert could be improved. I'd also like to see the product achieve high availability across clusters and to have more support for Apache CloudStack.

I think the UI could be developed more in the future because there are some issues with the graphics and some software that is very complex. A GUI for controlling the VMs would be a good additional feature. It's easy for us but it's difficult for others working with CLI.

In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs.

Monitoring and resolution are features which could be improved and I've found that if the product has not been used for some time, it needs to be re-set.
