Hello. After backup some Linux KVM VMs regularily seem to have done hard reset and cannot boot anymore. I fix these VMs by booting from live CD and using gpart -W /dev/sda /dev/sda and grub install Is there a way to fix that? PVE Manager version 5.3.7

Recently I had a power failure in the server room, after that all the servers started successfully and worked for two days without errors. But a day ago all the nodes in my cluster became red. I used my old simple script to restart all the needed services like this: #!/bin/bash service...

How can I make my NFS storage (used for backup) mount with udp option? What should I add to storage.cfg and how can I remount the storage with this option on the fly?

How can I make my proxmox ve host detect new hot-added hard disks without reboot?

Hi, Has anyone have success installing virtio balloon drivers in windows 2003 guest? I set up the machine according to this article http://pve.proxmox.com/wiki/Dynamic_Memory_Management#Enable_Auto-Ballooning_on_Windows_2003_.2F_Windows_Xp I first tried installing the balloon driver using the...

Hello, How can I correctly check KVM guests' cpu performance in the proxmox environment? I suspect that my VM's (windows guests) have much lower cpu performance than identical physical machines. I measured the cpu performance with the built-in benchmark tool of 7zip archiver (one thread). The...

Hi, the question is not very critical but interesting for me. I have planned the backup of some KVM VM's on a proxmox ve 2.2 server. Backup mode is snapshot (VM's reside on LVM). The backups are OK but two of the machines (the same ones) are backed up with suspend. I see in the backup log the...

I updated all my proxmox ve hosts in a cluster that night from 2.1 to 2.2. After the update one of my nodes begun to fall into general protection fault right or after few minutes after boot. Here is a screen http://s18.postimage.org/ew7hvrrg9/image.jpg The two other nodes of the cluster seem to...

I have a three node cluster. The cluster seems to work correct. The problem is: I can't launch the kvm console window from the other node (not the one on which the kvm guest is running). When I open the console window ot the different node it shows me a white window with some diagnostic messages...

The situation is: I have about 15 kvm guests on a proxmox ve host. It has 60GB RAM 15 kvm guests altogether are assigned 75 GB RAM. Most of the time they altogether consume about 50GB RAM. But there were several times when the RAM consumption of the KVM guests grew till the host's all available...

I have a 3-node cluster with a shared LVM SAS-storage. I created a VM 129 (the id is essential in this case), played with it for a while and deleted it from the web gui. I think something went wrong while deleting the lvm disk of that VM. And now I have a problem. When sitting on the same node I...

Hi, I have three nodes in a cluster with Proxmox ve 2.1 installed. An external SAS storage is used as the main shared storage in LVM mode. Everything seems to work almost fine. The migration works fine. The problem is that sometimes (once or twice a week) one of the nodes (the same one) becomes...

Hi, I have some VM's installed on three nodes with Proxmox VE 2.1. The problem is that the VM's won't shutdown when I click the button "shutdown" in the main interface. I would say it didn't worked in proxmox ve 1.9 as well without opening the console window of the VM. But the VM DOES shutdown...

I have two proxmox nodes in a cluster with directly attached shared storage (HP MSA 2000) where VMs are running. I also set up an NFS share on a separate OpenBSD machine as a storage for vzdump images. The backup process seems to run properly. According to backup logs it takes from 30...

Hi, the situation is this. During the backup process, when the snapshot method is used, the process may hang (while the VM itself functions properly more or less). I noticed that it happens when a VM (Windows guest only. It NEVER happened with Linux KVM guests) reboots. This occurs when I VM...

Hi, When I add a bridge device in the web interface of a physical server it says to me that I must reboot the server to apply changes. Why is it so? It is very complicated to reboot the physical server with a couple of VMs that MUST run in uninterruptible mode. Any ideas? Or do I miss anything?

Hi. I have an LVM storage on a proxmox server with some virtual disks on it. I want to move them all to another storage. The storage was created so: pvcreate /dev/cciss/c0d8p1 (adding a disk with 2TB space) vgcreate VGONVD3 /dev/cciss/c0d8p1 What I do now: pvcreate /dev/cciss/c0d6p1 (adding a...

I'm trying to move a volume group to another physical storage issuing a command: pvmove /dev/cciss/c0d8 and get an answer: Physical Volume "/dev/cciss/c0d8" not found in Volume Group "VGONVD4" But I am sure I created a physical volume using this device name like this: pvcreate /dev/cciss/c0d8...

I set up a shared storage for proxmox ve using an external sas controller HP 2012MSA and I think I do something wrong because my kvm's disks on the shared storage get corrupted when used by the secont server in the cluster. Here is what I did to make a shared volume: pvecreate /dev/cciss/c0d8...
