Couple of items, I've used Promox for about 4-5 years  now, very nice hypervisor have had no problems what soever

I current run it on a Dell R-610 with 96Gig of ram and 6TB of HD, hosting 5 linux servers and desktopsetup with about 8 domains and 1 email server all are Linux based, the mail server is awesome

system called Zimbra completely free, I'm hosting a number of open source decentralized social network, Peertube (Youtube work alike) , Mastodon (Socal Network) , Piwigo (Picture hosting), OSSN (Social Network)

, WebTrees (Geniology), OsClass script (ForSale/Want ads), Simple Machines (Forum), WordPress (Blogging site)

So I use it alot

I might also recommend highly the use of Virtualmin as a hypervisor I have used it for about 2 years and am a subscriber to both systems

Proxmox cost me 175.00  a year two processors 75.00 each for updates/upgrades and the Virtualmin is 7.50 a month for updates/Upgrades

I might also say the virtualmin really has a nice routine for easy installation and renewal of Lets Encrypt

Hi,

I just watched a video that covered the Proxmox Hypervisor.  Seems
simple enough.  I've used Oracle's VirtualBox for years.

So I did some research on what a vCPU is.  I was suppressed.  The math
given was (Threads x Cores) x Physical CPU = Number vCPU.

I have an old laptop that has 1 socket, 2 cores, four threads, and 4GB
of RAM.

Given the math (4 x 2) x 1 = 8 vCPUS.  Is this correct?

 From my reading it appears that RAM is not shared, so my bottleneck is
RAM not cores or threads.

I am a PHP developer and a local vps would need 2GB of RAM at a minimum.
  I have found a LAMP VPS will crash if allocated less than 2GB of RAM,
and will run will on 1 vCPU.

The good news is I really only need one VPS to be active at any given
time.

If I wanted to build a box that could run more than one VPS at a time,
lets say 4, and I wanted to allocate 2 vCPUs and 4GB of RAM I would need
4 threads x 2 cores to run the 4 VPS configured with 2 vCPUs each.

What about RAM.  Looks like I would need a minimum of 16GB of ram.

How much resources does the Hypervisor need, in this case Proxmox?

Thanks!!
Keith
