kvm

I got problem with a host network (pve-manager/3.4-6/102d4547 (running kernel: 2.6.32-48-pve)). I can ping everything from host but can't ssh to it and can't open any www even do apt-get update. I use pfsense inside kvm on the same host as a gateway (which works great) and another openvz guests...

I have an ansible playbook that clones a debian template, sets some kernel arguments via qm command, boots the VM, and then is supposed to remove the kernel arguments, so they would only be used/seen on first boot. I based my method off of this excellent guide...

Since we upgraded our cluster to PVE 4.3 from 3.4, all our OpenVZ containers have been converted to KVM virtual machines. In many of these guests we get frequent console alerts about CPU stalls, usually when the cluster node is under high IO load (for example when backing up or restoring VMs to...

Hello all, I'm having an issue with our setup that I just can't seem to lick. Having gone around in circles, I'm wondering if anyone here has any ideas, as it's probably something simple I'm missing. We have multiple hosts, each with 6 NICs in. The NICs are grouped into two bonds, and each...

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...

Hallo zusammen, Ich möchte über Proxmox KVM Server erstellen und bin gerade dabei ISO Templates zu integrieren. Standardmäßig kann man aus der GUI nur openvz Templates wählen. Meine Fragen: Kann ich die vorhandenen openvz Vorlagen auch für KVM Server verwenden? Oder von wo erhalte ich am...

Hello, I'm experimenting CPU and RAM hot plugging with KVM. I can add or remove RAM from a running VM. It works great! I have read that reducing RAM is not supposed to work, but all worked at the first try. Maybe I read outdated articles? (tested with proxmox 4.3, ubuntu 16.04 guest) I can...

Dear First Im super fan of Proxmox and any Linux technology, I have the following case: I had installed Promox on Dell Server and everything work very smooth, I installed SGM as VM, the application work fine but when need to upgrade the SMG it gave me the hardware not supported error, after...

We have a qcow2 image but the image is only 4GB in size but when we try and resize the disk and new unallocated partitiion is created and we have no way to extend the primary partition. How do we extend the primary partition from 4GB? We do not want another partitiion as we cannot even do...

Hello, I am trying to figure out how things are working when related to disk size and disk image and real disk size. I have an NFS shared storage with 10T of disk space. This storage is a FreeNAS ZFS storage and is available on all nodes of my cluster (shared using NFS). The size of the...

I am running Proxmox 4.2 fully patched with two KVM systems. The first is running Windows 10 Pro and the second is running FreeNAS 9.10. Each of the KVM's can be pinged by the Proxmox host and any other devices on the LAN. However, the two CANNOT ping (or any other network traffic) each...

Upon upgrading our cluster to PVE 4, I just realized that live migration of KVM guests on ZFS local storage (zvol) still does not work. Since vzdump live backups do work (presumably using ZFS snapshots), I wonder why it's not implemented for migration, and when is it expected? Is it on the...

This sounds like a newbie question and, well, indeed it is :) Basically, I am trying to figure out how do I "update" a Debian container. If it were a KVM installation, I'd do the usual change of /etc/apt/sources and then apt-get update/dist-upgrade etc. I don't know what's the right thing to do...

Hi, when I set the CPU type on a virtual machine to "host", I get an error messages like "kvm [2745]: vcpu0 ignored RDMSR: 0x1c9" after each reboot of the virtual machine. I have read that these messages do not mean much. Does anyone know how to suppress this warnings? I have already tried...

Hallo, wenn ich den CPU-Typ einer Virtuellen Maschine auf "Host" stelle, erhalte ich nach jedem Reboot der VM einige Fehlermeldungen der Art: "kvm [2745]: vcpu0 ignored rdmsr: 0x1c9". Ich habe gelesen, dass diese Meldungen keine große Bedeutung haben. Weiß jemand, wie man sie abstellen kann...

Hi, I've readed some posts and forums (proxmox and out of proxmox docs), but I cannot seem to get the answer. KVM is supposed to have live snapshot, but in all my 4 kvm VMs whenever I create or delete a snapshot, the VM gets completely locked. It doesn't accept connections, ssh drops if I...

Testing Proxmox VE 4.2 as an alternative virtualization solution for larger installations with shared storage we ran into several issues, including a severe problem: When booting up a server with NFSv3 shares the start-up of kvm vm guests "on boot" inconsistently* fails with " {hostname}...

Hallo, ich bekomme die Netzwerkkonfiguration nicht hin. Ich setze Proxmox 4.2 ein. Der Host hat die Ethernet-Schnittstellen eth0, eth1 und eth2. Die verwendeten IP's sollen im Beispiel sein: eth0 134.60.1.2 Für den Host eth1 134.60.1.3 Für VM1 Ubuntu Server eth2 134.60.1.4 Für VM2...
