qemu

Greetings I'm testing cloud-init on a brand new Ubuntu 18.04 VM. My problem is that the IP of the VM and the GW are not on the same subnet (which is quite usual for a floating IP), so I guess the whole process of setting network fails. I can see the parameters in...

I am currently running Qemu-KVM on an Ubuntu 14.04 host. Since I don't have spare hardware, I will need to backup my current VM's to restore them on the new ProxMox environment. I understood that in theory a KVM VM disk (either raw or qcow2) can be used as disk on ProxMox (5.2) too, so would my...

Hi guys, I setup a 3-node experimental cluster with LVM on iSCSI (FreeNAS) as storage. Live migration fails when the CloudInit drive is attached but it works fine without the CloudInit drive. Is this normal? Live migration with the CloudInit drive attached gives this error...

Hi, I've several Win10 and Server 2016 machines running, all with an active QEMU guest agent. I updated (0.1.149) all of them except one server fails to install. Any idea how to solve this? I'm aware that this is not a PVE problem but I'm hoping that someone here has an idea. Thanks in advance

I am running the following Proxmox version: pve-manager/5.1-46/ae8241d4 (running kernel: 4.13.16-1-pve) I have created VMs from the following Debian iso, stored in the following location: /var/lib/vz/template/debian-8.7.1-amd64-DVD-1.iso After creating the VMs, configuring them, maintaining...

Hello, I have been trying to find a solution to this annoying problem for over six months. Have updated both servers (one is a community edition subscription and one is without subscription). This happens with both of them. Whenever I try to have an automated or manual backup of my VM (I don't...

Okay, so before I delve into this, I'd like to point out that the real applications to a concept like this are fairly limited, so please don't just respond with "Why do you need this?" I'll tell you the answer right now: I don't. BUT, someone else might. So if you have even a little bit of...

I've been running Proxmox on a new AMD Ryzen 1700x server for the last few weeks and because I'm using GPU passthrough I've been using the testing repository because of certain AMD patches that are available in the newer kernel, this has been working great! Yesterday I decided to run an apt...

This morning, I updated my home server from PVE 5.1-43 to 5.1-46. Before the update, I had a handful of QEMU VMs that I configured serial sockets for so that I can use xterm.js (it's much faster when I'm on the go since I have a very restrictive bandwidth that noVNC can't quite make it through)...

Hello, i have a Qemu VPS Cloudlinux 7 (centos 7) with LVM. I'm tryng to enlarge the root partition using Gparted Live CD but i have this error when i try to enlarge SDA2: "partition length of 4401920000 sectors exceeds the msdos-partition-table-imposed ..." My Volumes details: vgdisplay...

I am completly new to proxmox. I am trying to use this plugin for jenkins which should allow for adding proxmox VMs as jenkins slaves. However when reading about it, it says ".only Qemu virtual machines supported." Right now the plugin does not find any virtual machines or nodes and I was...

Hello I've seen some vulnerabilities in qemu-kvm, that were recently patched. For ex, CVE-2017-7980 In the redhat announcements, i saw they require a stop of all VMs for the update to take effect. Do we need to follow the same procedure when proxmox updates the qemu? Or it's patched in...

According to this article: https://www.linux-kvm.org/images/c/c5/Kvm-forum-2013-High-Performance-IO-for-VMs.pdf Using netmap with VALE switch ( http://info.iet.unipi.it/~luigi/vale/ ) will get a much higher throughput even 5x than virtio (from presentation, for 64 byte packets up to 2.5Mpps in...

Good day! Today i try to migrate hyperv VM with Windows 10. I have copied VM in vhdx format on Proxmox server, then i used: qemu-img convert -O qcow2 Windows10.vhdx /var/lib/vz/images/Windows10.qcow2 I have *.qcow2 image at output. Then i've tryied to connect disk to new installed VM, but i...

Hi, For quite some time, I have been experimenting with using the QEMU Agent from the commandline. I have enabled the agent from the web gui and installed the qemu-agent package in my guest. I am getting the results but I am not able to the same in a scripted manner. Here is what I am doing...

how do i set the boot order of a VM via the api?, i cant seem to find it in the config or any other documentation.

Hello there, I saw in the device manager this unknown device "ACPI\QEMU0002" and already googled about it and tried all virtio drivers. But none is correct. I also installed qemu guest-agent, but it didn't solve the issue. I've got this problem on Windows Server 2012R2 Essentials and Standard...

Hi guys, Need some bright minds in the Proxmox community :) I setup a storage cluster using Ceph (as the title suggests). It's a fairly large cluster consisting of over 200 osds. When I bench the cluster using rados bench, I get exactly the kind of performance I was expecting to get... doing...

I thought qemu-2.7 had solved all issues regarding iothread but apparently you are still not able to make a backup if iothread is enabled. Am I missing something?

Hi, there! Today had a strange situation with image restore: 1. Source server was Proxmox 3.1 (pretty old, i know), everyday backup snapshot is made on NFS. 2. Today had a plan to migrate one qemu VM to new 4.2 proxmox cluster. 3. Stopped VM (Ubuntu web server), tried to make a fresh backup...
