qcow2

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...

I have just installed Proxmox VE 4.2 (on ZFS), and tried to restore a few VMs to it (from NFS). Regardless of the fact that all VMs used qcow2 disk format when they were backed up, Proxmox creates ZFS zvols for them, instead of qcow2 files. Is there any way to restore VMs directly to qcow2 on...

Hello! on our Porxmox VE 4.2 we have a working windows XP guest with a "raw" disk image. In order to being able to use live snapshots, i want to migrate the raw image to qcow2. I did that by using the PVE GUI (after preparing the storage to be mounted). Now, when i want to start the XP guest, i...

Hello, Greeting from new member :) I'm running Proxmox 4.2 HA. I'm taking live snaphot from all of the running KVM from the GUI. The result is vzdump-qemu-kvmid*.vmz.lzo. I'm using qcow2. How to test or verify that the backup file is fine or not? I would like to test restore but this is a...

Hi, For some reason, QCOW2 appears to be taking the same space as RAW when a new VM is created. In previous versions (3.x) QCOW2 HDD would start from a minimum and then expand, i.e. I would set it to 100GB which would be the maximum and it would grow until that. It looks like in the new 4.2 by...

hi, i cant backup one of my vm's: what is the issue? version:

dear community, i did a fresh install of proxmox ve 4.2 and tried to import some existing appliances in ova-format like i used to do using proxmox ve 3.4 by pushing the disk image whether converted in qcow2 or raw format to it's respective place in /var/lib/vz/vm-id/images replacing the...

Hello to all, from few days ago i have encountered a problem with one of mine kvm machine, i cant start the machine beacause the disk-1.qcow2 is corrupt. If i run qemu-img check -r, all the free ram of the node (40 GB) will be consumed in just 3 seconds and affect all the virtual machine from...

Hi there, I think this might be a bug or a feature that is not yet implemented. I was migrating from a single server to a cluster. Today I migrated a VM that was a linked clone. The process I followed to do the migration was to create the vm and then overwrite the qcow disk file. The VM works...

Hi, I want to mount qcow2 image file, but get this error: mount: you must specify the filesystem type I follow the steps provided in Debian Wiki: modprobe nbd qemu-nbd --connect=/dev/nbd0 imagename.qcow2 The image is loaded correctly, but I cannot mount it. fdisk -l /dev/nbd0 WARNING: GPT...

Hello, I'm migrating from proxmox 3.4 to proxmox 4.0 and therefore I'm migrating my containers to LXC. I see that LXC containers use raw disks. With OpenVZ, containers only used the necessary disk space, but now I have a container that uses the entire 4GB raw disk image when it only needs...
