exceed the core number

[MRs ghost]

Hi
I have a server poweredge R740 with 2 processors and each processor contains 28 cores and I wanna to install proxmox on this server and running 20 VMs windows 10
And give each vm 4 core then I will exceed the core number (56)
Is this can make a problem in future?

that is called overprovisioning, and you certainly can.

Just realize that you are not guaranteed processor availability if you generate more load then you have cpu available, so this isnt good for static load applications.

@alexskysilk answered already for CPU overcomittment - and that was your question

Let me add as a side note: more problematic than CPU is overcommitment of memory. Try not to do do this.

Have fun
