Hello, you used an administrator PVE their workplace?
If yes, I asked him to share his impressions.
And if you can share that use OpenVZ or KVM virtualization.
I am thinking to transfer part of servers operating from real machines virtual machines.
I am trying to gather impressions on how the PVE under load.

Sorry for my bad English

Hi,
do you mean, that I use pve for virtualisation in the comany where I work? Yes with 7 servers.
Or, that my admin-workstation is an pve-host? No, only a test laptop at home.
If yes, I asked him to share his impressions.

OpenVZ is a nice solution for lightweigt servers like web, dhcp and dns (the VM use the same kernel like tho host). If you need kernel-modules inside the VM go for kvm.

The bottleneck with virtualisation is normal IO and then RAM - use fast storage (raid-controller) with plenty of RAM and you are happy ;)

I think Udo just said he uses it at work (professionally).
If by "their work professionally, not tests" you mean "do you use Proxmox at work to run virtual production servers, not only test servers", I'm sure the answer will be yes, as well..

As for asking for impressions about load: I'm sure a standard answer will be to try a test setup and see how it works... Apart from that, I think there are quite a number of forum posts that give more information on number of virtual machines per physical server etc.

I'm running a home/hobby system on a machine with 8GB RAM; have a KVM router, a couple of db servers, a Jenkins CI server etc running. The thing is, they don't run under a lot of load so it's an easy fit.
As said, on production/bigger systems, your storage and memory will likely have a large impact on performance..
