kvm

Problem Description: Many people using Promox (and other KVM/QEMU based hypervisors) on Jasper Lake platforms (N5105, N6005) are experiencing kernel panics and/or hangs of their guest VMs. Both Linux (OpenWRT, Ubuntu) and FreeBSD (pfSense, OPNsense) guest VMs are affected. The host itself...

I'm running a Gigabyte GA-6LISL mITX server board with TrueNAS Core and I am banging my head up against the wall trying to vKVM in. When I attempt to launch the Java KVM client from the web console I get a generic "Connection Failed" error. After doing some research I figured I would give...

So this is fun, I just woke up to a clone job of my laptop being finished, it was kind of an experiment. It runs OpenSUSE, so it's got a BTRFS root and snapshots triggered by package manager. I wanted to back it up so I could have a copy of the machine to run elsewhere, here's how I did it...

Hey, I've got vSphere 7 and keep wondering at least once a year if I should ditch vSphere for something open source. I'm thinking KVM-based, but have my eye on the Illumos/FreeBSD bhyve projects, too - although what I've tried of them has been really rough around the edges. Also open to Xen...

HI, I build a one server for Truenas at home. The system is build on an Asus Z9PR-D12 MoBo. I love the spec but I hate 2 issue with it. As I have a P600 GPU for plex transcoding with no monitori plugged on it, I would like to force display on OnBoard GPU. I cannot see anything when system...

Hi all, I've recently taken possession of a Dell SC7020 storage unit (Compellent) after a business went belly up, but am having great difficulty in getting the unit online / functional. Specifically, I am unable to access the Web GUI of SCOS and cannot discover the unit via the Dell Storage...

Ours avocent autoview 3100 KVM switches are getting old, and they require some fiddling with java security config so the kvm java applets work. Are there any affordable USED kvm-over-ip solutions that either dont use java applets or at least have them properly signed? One port/machine is...

Hi, I've setup a Proxmox-Hypervisor and got a total write amplification of around 18 from VM to NAND flash. Can someone hint me how to improve this? Server setup: Supermicro X10SRM-F, Xeon E5-2620v4, 64GB DDR4 2133 ECC root drives: 2x Intel S3700 100GB (sda/sdb, LBA=4k) mirrored with mdraid...

This error is driving me nuts and I can't seem to figure out why it's failing. I've got a basic install of Debian Buster with qemu/libvirt and am utilizing Cockpit as the simple server mgmt UI. VM creation and everything works fine via Cockpit and even using the console within the web ui works...

Headlines are supposed to be dramatic and only half-truth, right :p After some talk on other threads about power-consumption, AMD, Intel and servers, I thought I'll get some real power numbers on the on-prem servers I usually setup at my customers. Some questioned the power numbers I've been...

It was my belief that AMD's newer CPUs was ahead Intel now, and I finally decided to get my first test-server, Asrock board + Ryzen 5 2600 (no GPU) to test it out. My use-case is std. business servers (Linux KVM/QEMU: VPN firewall, Windows AD, Windows RDP VMs, Storage, Web, Mail, FTP and the...

Hi Guys, I have proliant 380p's and want to setup each server to do the following tasks. Run a computationally intensive app that will utilise 95% of the CPU's resources (machine learning / AI), the rest of the CPU power will be used for the following: Run 16 virtual machines that will need...

Hi everyone, So obviously Alpine is getting a lot of attention lately since Docker is popular, but it also has a plethora of packages commonly available in larger-footprint distros - namely KVM, libvirt and ZFS. It runs easily from RAM since it's so small, and is also unencumbered by systemd...

Hi, I am experimenting with a KVM machine I put together using Alpine 3.6.2 with ZFS, and I was wondering if anyone has any ideas how I can manage it from a Windows laptop? I tried to install virt-viewer MSI, but the installer just exits after clicking the first 'next'. Can anyone suggest...

Hi! We just got two new DELL servers in the office with the following specs: - 2TB Disk Space (using RAID 5) - 192GB RAM - 2x 8 code Intel CPUs each (32 cores each) And we're now discussing which virtualisation solution would be the best to host multiple different environments (a kubernetes...

I'm stuck in my own thoughts when it comes to my next home server. I'm currently running out of space in the current system and the setup feels old and inefficient. APC SmartUPS 1500 (bought used, probably over sized for the task, noisy when the fans runs every now and then. Efficiency? I have...

Hi Not sure if this is the best place of the forum to post this in. Feel free to move it if it fits better in another section. This might be a bit long but stay with me :) I have had a home server of some sort running for many years. Started out with different Linux distributions about 15...
