I tried proxmox 6 and 7 in production with ZFS and RAM was the bottleneck Now, I am thinking to move from ZFS to BTRFS that my customers need snapshot and fore data safety and myself want better RAM saving any advice in this part

for example the below mentioned new intel processor Intel® Xeon® Silver 4310 2.1G, 12C/24T, 10.4GT/s, 18M Cache, Turbo, HT (120W) DDR4-2666 the part 12C/24T as per my understanding is 12C = 12 cores 24T = 24 thread per core am I right? check this link...

what about intell 1 socket x 12 core per socket x 24 thread per core = 288 vCPUS (If I am right) will it have good performance? or I have to do another calculations?

The point is I would like to calculate the host resource to purchase to provide 62 nos. of 4vCPUs VMs. load may be 50% so, how can I decide no. of sockets, cpus, and threads?

I am trying to get releation between threads and vCPU like this vCPU numbers = No. of CPUs x No. of cores per CPU x No. of threads

does proxmox support virtualization of hyper threading (using multi threads available on the same CPU)?

please note also the name of bridge will be changed

Hello I have proxmox working on a server with 20 VMs sold to clients Now, I want transfer VMs to another servers so, how can I change the IPs of these VMs

Did you try hostbill? I am thinking to try it can you advice on which system I have to use

so, after gave up. what system do you use?

Hello Recently, I used module to integrate whmcs (billing and automation system) with proxmox, the reason was when customer make order then whmcs will create bill and send order to proxmox to create VM and then give client dashboard to control his VM. I used module from company its name...

Which billing system do you use whmcs or hostbill?

I think that was old

:) so I can put any number of VMs on host provided that no. of VCPS = physical CPUs x (no. of threads x no. of cores) and adequate no. of ram am I right now?

do you mean by vm not host. I may be confused on this

but I read also in redhat website that maximum vCPUs is limited to 160 per physical server, is that because of license also?

Hello I got to know that in windows you can create only 64 VM per server and also in VMware you can assign only 128 Vcpu. so, what is limitations in proxmox? please note I talk only about KVM because it is not applicable for containers

:) ;)
