kvm

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 Maybe I read outdated articles?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...

Hi all, I've got plenty of GBs free but df -i reports: root@server1:~# df -i Filesystem Inodes IUsed IFree IUse% Mounte d on rootfs 5029888 5029888 0 100% / udev 1023481 336 1023145 1% /dev tmpfs 1024970 317 1024653 1% /run /dev/disk/by-uuid/1c56ce75-4d63-4489-9fce-c257d5269afa...

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...

Hello team, it's a pleasure to talk to you. I've been researching on what I need and I found what I was looking for so I am here. Whenever my storage falls my virtual machines lose connection with the disc. My storage consists of a FreeNAS using QLE24xx plates, the servers where I have also...

Good afternoon friends. Whenever I need to shut down or take a virtual machine takes enough. Almost 5 minutes. Is there anything that can be done to improve this time?

Hello, the title describes the problem pretty well. It's a single node with no cluster or any "exotic" external storage. The problem has been happening for a while now, may be some months (we've learned just to not backup entire VMs and not to restart them unnecesarily, and never at heavy usage...

Hi there, I have a problem with my configuration. Basically the vmbr0 has OpenVZ containers which are working as intended. I added a new KVM which I want to use on a different subnet and after reading for days I cannot come up with a working configuration. I think it has something todo with how...

This problem might have been discussed before on other threads, but I feel it is unique in my circumstances. I've installed PVE 4.1 on Debian Jessie on 2 separate machines, and clustered them together using instructions in the PVE Wiki. I'm not able to use the NoVNC Console in PVE using Safari...

Hi, I have 2 KVM VMs (KVM1 and KVM2) connected on the same host's vmbrXX (bridge mode). I would like to isolate KVM1 from KVM2. I tried to use the proxmox firewall and add the 2 following rules for KVM1 (and the firewall option is ticked on the nic): [RULES] IN DROP OUT DROP But I can ping...

Hello everyone, hopefully someone here can shed some light on what may be going on with my only KVM VPS that i'm running. I mainly use OpenVZ on Proxmox but for this particular VPS, because it's running under CloudLinux, I had to use KVM instead. The VPS ran fine for almost a year but now it's...
