I was looking at the docs about enabling NUMA because I have dual Xeon E5-2650 v2 processors on a dell R720 server. I have searched everywhere to find a good guide to enable NUMA according to the number of nodes and sockets.
Anyone has tried it and could help?
I am experiencing some weird problems with TwinCAT (TC) in a Windows-VM. Because these problems do not occur with a different hypervisor (vmware ESX or HyperV), I suspect that the problem is related to Proxmox, KVM and/or their implementation of nesting. But first things first:
I have Proxmox VE 7.0 running on PC with AMD Threadripper 2920X (12C/24T). SMT (or Hyperthreading) is enabled. CPU has two NUMA nodes. I have two VMs:
1. WIndows 10 VM for gaming and work.
2. Linux VM that is hosting game, web and mail servers.
Both VMs have high CPU utilization. Windows...
Thanks for the PVE 6.4 release! The Live-Restore feature is especially interesting to me, because I've always looked for ways to make the restore faster in order to keep disaster recovery times a minimum.
Main Node has 16 cores / 32 threads
VM 101 has 32 vCPUs, because the database...
I'm new to proxmox and experimenting with how well Windows 10 will run on proxmox on my PC. I'm facing a bit of an issue with the CPU frequencies either showing incorrectly or something is wrong in my configuration.
I have my CPU overclocked in my BIOS to 4900Mhz. The CPU has 8 cores, all of...
I am currently looking to use proxmox for my cluster but i have some consernes..
can i put all the cpu power, memory power on a single pool so for exemple i can use 4core on one node and 2core on an other node and for memory i use 4GB on 1 node and 1GB on an other node. is it something...
I'm creating VMs using templates on thin lvm storage. I create the templates using various values for RAM and CPU, so template could have multiple CPUs or a big amount of RAM. Then on next builds, after clone I set CPU and RAM for new vm.
My question is that does having high number...
i have my main pve1 with 40GB Memory and 8 cores
then i create a new pve2 with 64GB Memory and 10 cores and join pve1 to pve2
so does this allow me to use 50GB memory and 12 cores on one vm in pve1 ? this is just an example as i need to know if its possible to use higher values then with one...
Hello. I already installed macOS using Proxmox on my rig. My CPU is 3rd Threadripper 3960x. I see little lags when I am using macOS and try to find reason. I found here that is not recommended use maximum cores of your CPU for VM (that was my case. I had set 3x16 cores) and now beginning my...
I've noticed that lxcfs has virtualized the /sys/devices/system/cpu/online dir since lxcfs version 3.1.2, but it's not working for proxmox LXC:
After upgrade the proxmox, I saw the lxcfs version has upgrade to 4.0.1, but it seems not working:
My hardware + software for work 0-24 all day as home server:
CPU i7-4790K, 32GB RAM but if not needed all, I can use with only 16GB too.
HDD: 2x 1TB HDD (Seagate Enterprise Capacity, ST1000NM0008) with software raid
Latest Debian + software raid + latest Proxmox install, all works...
When I checked the Task Manager in Windows 10 and viewed Performance, the selected CPU is worded "Common KVM processor" instead of name of the CPU? Intel i7 8600K. What can I do to make it read the CPU name instead of common KVM processor? Does correcting the name affect the overall VM...
I have proxmox installed on a server that has 2 Xeon x5570s inside of it each one has 4 cores and 8 threads. My question is how should I configure the CPU hardware for my Windows VMs? should I set the CPU configuration of the VMs as 2 sockets and 1 or 2 cores or should I set it as 1 socket and 2...
I have a slow problem with my VMs (linux / windows) under proxmox, despite the server is efficient server (12 CPU, 64 GB RAM),
I gave the machines a lot RAM and CPU but still the slowness exists, as well as the internet connection is perfect
I have the following setup:
Windows 10 PC with Virtualbox with Proxmox running inside. VM with Proxmox was given 6 cores (I have Ryzen 1600 with 6 physical cores). Inside Proxmox I have created an Ubuntu Server 18.04 VM (1 socket, 4 cores, 4 vCPUs, CPU limit: unlimited)
Then I try...
I'm in a muddle with setting the number of cores, CPUs and Threads
I use proxmox on a machine with 1x Intel Xeon D-1520 processor. This is a 4 core but 8 threads. I have only 1 VM running.
Proxmox 5.1 summary for the node reports 8 CPUs
However when setting the options for the processor in a...
In proxmox5 cpu setting have diverged from all the documentation.
It seems that cores setting is gone, as well as cpusets, and right now only cpulimit prevailed.
First, documentation thinks otherwise. Very probably should be updated.
Second, this may be a problem if the programs in the...
As I create new VM for web site I'm in doubt if I should use kvm64 vs host type of CPU for VM.
Choose host should looks like can give me more real cpu power (but I limited by real physical cores number), while kvm64 can be set to as high as 128, and (as I can imagine) will share the same...
My CPU is i7-4770, but when I choose Haswell as the Processor type, it would not boot up, so I am using "Default (kvm64)" under VM setting, and it works OK.
I have two questions:
1. Does Proxmox optimize the VM depending on the CPU type? Or it does not make much difference if I left it as...
I have been meaning to ask for a while,
I have a server with 2 x Xeon E5-2650 CPU each with 8 Cores, Total 16 Cores.
When I look in the Proxmox VE Web pane.
It shows a total of 32 x Intel Xeon CPU E5-2650 @ 2.00GHz (2 Sockets).
When I'm setting up my VM's do I use the actual sockets...
