We have developed a tried and tested method to set up servers and it works well once you know how you want your servers to work.

What is most valuable?

It's a solid, stable and powerful open source virtualisation product that has allowed us to bring virtualisation to smaller SMBs at an affordable price.

How has it helped my organization?

All our client servers are now virtualised, which has reduced the risk of downtime due to a server failure that used to happen with non-virtualised servers. Servers can be backed up using snapshots etc.

What needs improvement?

Storage IO management seems the weakest link although this could be hardware related. On decent servers this is not an issue but on smaller custom built servers we have occasionally had issues with IO speed. It is a well thought out product and the newer versions just seem to get better n better.

For how long have I used the solution?

We've been using it for seven years.

What was my experience with deployment of the solution?

There have been no issues deploying it.

What do I think about the stability of the solution?

There have been no issues with its stability.

What do I think about the scalability of the solution?

We haven't had any issues scaling it for our needs.

How are customer service and support?

I've never really needed it as I've been able to work out most things intuitively.

Which solution did I use previously and why did I switch?

We also looked at VMware. Our perception is that this is a superior product but that is subjective as it is not mainstream.

How was the initial setup?

It's straightforward. We have developed a tried and tested method to set up servers and it works well once you know how you want your servers to work.

What was our ROI?

It's hard to quantity but using Proxmox has significantly boosted our server capabilities and service offering increasing our revenue.

What's my experience with pricing, setup cost, and licensing?

It's open source and provided one has enough experience with Linux and servers it doesn’t cost much other than time to become an expert in the product.

Which other solutions did I evaluate?

We also looked at VMware.

What other advice do I have?

It's well worth using. It's highly recommended and we have had no issues.

Performs well with Windows but lacks Mac support due to Mac's EULA

With respect to some of the cons, Proxmox VE performs well enough with Windows if you use KVM's virtio devices in lieu of emulated hardware. However, the freely available virtio drivers are not WHQL-certified, which produces annoying error messages when you attempt to load them.

With respect to the lack of Mac OS X support, a large part of this is due to Apple's terms of use for OS X. I can't really blame Proxmox or the KVM folks for not pursuing Mac OS X support since doing so would violate Mac OS X's EULA and could potentially get them or their customers sued.

Lastly, I can't say that I've ever had any stability issues with the Proxmox VE web interface, but using the graphical console can be a struggle. I don't think I've gotten it to work in anything except Mozilla Firefox.

The limitation to running on Mac platforms is quite a disadvantage to the many large companies using this kind of OS for their machines. Luckily there are many other alternative virtualization productss in the market that provide similar or better features.
