kvm

Hi, I'm running a hyperconverged cluster (Proxmox & Ceph) across three nodes. I've noticed the swap usage is creeping up. Each node has 192GB of RAM and 8GB of swap. Ever since system install I've reduced the swappiness to 10. Looking at what is actually eating the swap, it's a few KVM...

This is a tutorial on how to make fstrim run more often or on days that you wish. This could be handy if you have stuff continuously writing to the drives which then later gets deleted, which would cause it to create a large amount of unused data. For example, I have a Minecraft server running...

I have A LOT of VMs running on Proxmox VE across several Servers. Most of the VMs run Debian GNU/Linux Bookworm. Overall the KVMs seems quite inefficient, especially in Terms of: - RAM Usage (a bit less on Xeon E3 v5/v6, since up to 64GB RAM can be used there) - Disk Space (each VM takes 16GB...

Running a VM via the shell (to institute additional command line parameters) results in the syslog being flooded with qmeventd events like the following: qmeventd[1038]: error parsing vmid for 3371241: no matching qemu.slice cgroup entry qmeventd[1038]: could not get vmid from pid 3371241...

Hello everyone, I posted something similar about this a year or so ago. However now my CentOS 7 box is EOl and I need to move to a different hypervisor. Proxmox is my obvious choice, but I am having some issues with importing my VMs. Here is an explanation.... I am currently running Proxmox on...

Hello There, Is it possible to rate limit (network) an VM on a static value except for certain IPs so that the assigned IPs bypasses the network rate limit? Thanks in advanced!

Hi I'm currently experiencing hardware issues. I am having to change things round to try and get things working; plug in a GPU etc Is there any way to avoid the ID of passed pcie & bridged network device changing? Each time I plug in I have to currently switch items to get things to work, and...

I understand that LXC has less overhead than a VM, but the difference is so big that I suspect misconfiguration on the VM. Hopefully I can get help to correctly configure a VM for better performance. LXC specs: VM specs: Host specs: Using this fio configuration: [global]...

I have a Ryzen 5600x. Is there any CPU flags I can pass that improve performance ? I am currently passing through host model I am not particularly concerned with the security implication

I'm looking to recruit support for my request to post (if it doesn't exist) or make more visible (if it does exist) a web page that lists the releases, their beta/stable status, and release notes with known issues of the VirtIO KVM Windows Guest drivers. If you agree, please go to this post and...

Irgendiwe schaffe ich es nicht die richtige konfiguration für den Container zu setzen dam er zugriff auf /dev/kvm hat. der grund dafür ist das dosemu2 /dev/kvm nutzt um einen ibm computer mit 4mhz zu simulieren .... bin gerade am setup eines BBS mit doorgames aber die kvm zugriff kriege ich...

We've recently discovered the performance improvements for choosing a CPU model which most closely matches our cluster. I want to work out the best way to determine the correct 'lowest' cpu model for the cluster. We have both: Intel(R) Xeon(R) Gold 6140 CPU and Intel(R) Xeon(R) Gold 6330N CPU...

Hello there, I have some raw template images (e.g. debian11.img) I want to import to my Proxmox VE instance to use them as templates to create KVMs. I use a ZFS volume, local-zfs. When I searched the web, I found this thread from 2015...

Hi, I have just made a fresh install of proxmox (8.1.3) and I am trying to get virtualization up for my truenas vm. I have an intel cpu and have virtualization enabled in the bios. From installation I have been having this error. When I ran the installer I got the error "No support for...

Hello everyone, For a month and a half I have been looking for a bug that does not allow the September, October (KB5031361) and subsequent updates to be installed on Windows Server 2019, the updates are installed during operation, the machine is restarted so that the Windows update progress...

Recently upgraded from PMX7 (Proxmox Version 7 or PVE7) to PMX8 (Proxmox Version 8 or PVE8), and I noticed the passthrough doesn't seem to work the same way in the UI it used to. <= PVE7, the way you knew IOMMU/etc wasn't working is that in the UI, the "MAPPED DEVICES" dropdown would be empty...

Hey everyone! As far as I understand, my Proxmox 7 cluster, installed on top of a Debian 11 Bullseye, uses systemd-timesyncd to keep the clock in sync via external NTP servers, configured either in /etc/systemd/timesyncd.conf or in a separate file inside /etc/systemd/timesyncd.conf.d/. All of...

Hi, I was thinking to check out the WHONIX on proxmox. They have a KVM install. I was wondering if anyone already has tried setting it up and if there are any tips on setting it up? Cheers

Hi, Been debugging why my Windows 10 machine (VM) is so darn slow. Found this, and it solved the issue. So far so good - until I tried to run a VM in Hyper-V on that same Windows 10 guest. Turns out you need to use host and not any of the other CPU types. It was absolutely flying on...

My Proxmox host has multiple NICs and I can make changes to the physical networking if required. I have used VmWare earlier but I am new to Proxmox & KVM, thus also challenged with the virtual networking in this environment. Here's what I am trying to achieve: Setup 2 virtual machines, both...
