The tool is very stable. Since we provisioned the box, it hasn't been rebooted yet. It has been 1400 days. I rate the stability a ten out of ten.

It's a very stable product.
View full review »I would rate the stability of KVM as a six out of ten. There have been stability issues and occasional crashes with KVM, especially if incorrect commands are executed. Unlike VMware or Proxmox, which offer additional management tools, KVM is more sensitive to command errors and requires precise handling to avoid disruptions.
I can't comment on whether it is stable or not since I have not yet used it to that extent.

View full review »KVM is stable, but the product from VMware E6 is not stable and I sometimes have issues with it and then the usage of RAM and CPU is costly in my experience.
Stability-wise, I rate the solution an eight out of ten.

Stability is guaranteed due to its open-source nature, ensuring reliable deployment. KVM's internal deployment is secure. The primary aspect is its upcoming release of significant features. I would rate it nine out of ten.

When the product is used frequently, it's stable, but if we don't touch it for some time, it needs to get synchronized again with the VGA or the HDMI, and there can be problems with that.

We have experienced some strange problems with instability using KVM. If you install a new driver, HBA, or a new PC network adapter, then you can have problems because of the process of certification for these devices. It happens because KVM is a solution that supports many different kinds of hardware, unlike VMware which is much more restrictive in terms of what it is compatible with. The problem with having such an open solution is that it can also be the cause of issues with stability.
