Temporary use of disk space when deploying KVM with qcow2 ?
Hello,
I'm using libvirt to deploy a series of 7 KVM (in qcow2 format)
sequentially. The base image of the qcow2 is an ubuntu server of around
1.6GB.
The environment where i am doing this is a Live USB Ubuntu with a
persistence file (so that changes made remain).
So, the problem:
* If the persistence file (i.e. free disk space in the live ubuntu) is up
to around 1.6GB, the qemu process of

Questions about qcow2 file size management
Hi all.
I have a few questions regarding the qcow2 format.
1/ Allocated size vs. file size
When creating a VM, I indicated a size of 10 G.
$ls -lsh
7,7G -rw------- 1 libvirt-qemu libvirt-qemu 11G oct. 14 10:04
prod.qcow2
The allocated size is lesser than max size. Alright.
I think I more or less grab the difference between allocated size and
file size, but I'm not sure I get the point

Re: Create qcow2 v3 volumes via libvirt
Hi Eric and list,
I had another production VM start pausing itself. This one had been
running for more than 4 years on a 60G LVM volume. It has had the
occasional snapshot during that time though all have been "removed"
using the virt-manager gui so I used qemu-img as you suggested.
# qemu-img convert /dev/trk-kvm-02-vg/rt44 -O qcow2 /mnt/scratch/rt44.qcow2

This is not true. The file format only contains the relative path.
qemu-img info will print an absolute path, but it's not stored inside
the file.

thanks . now i know qcow2 only store relative path.
look at my error message, 6a3256bb-b247-4fb5-9f75-8ffa7151eeda i a symlink to a LV. it is the backing_file of several images(LV)..

KVM virt-install on disk image - "no space"
I guess I need the list again.
I try to install my first KVM guest. Here is what I do, and finally,
what I stumble on.
First I created a qcow2 img:
# qemu-img create -f qcow2 /var/lib/libvirt/images/test1.img 15G
And I created a network bridge (not essential here)
To get a text-based install, I followed this how-to:

[PATCH v2 3/3] rhv-upload: Support qcow2 disk format
When using oVirt >= 4.3, we can enable the NBD based backend in imageio
by specifying that we transfer raw data when creating a transfer. With
the NBD backend, we can import to disks using qcow2 format.
To make it work, we override output#transfer_format to return always raw
format, but we create the disk on RHV side using qcow2 format.
The pipeline looks like this:
