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 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...

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...
