[libvirt-users] Resize qcow2 disks

Good morning. I already tried: 1. http://michael.orlitzky.com/articles/resizing_a_kvm_or_qemu_disk_image.php Result: OS system can't see the disk space sudo qemu-img resize /var/lib/libvirt/images/mysql-1.qcow2 +8G ls -lath /var/lib/libvirt/images/mysql-1.qcow2 -rw------- 1 libvirt-qemu kvm 10G jun 1 15:35 /var/lib/libvirt/images/mysql-1.qcow2 # pvresize /dev/vda5 Physical volume "/dev/vda5" changed 1 physical volume(s) resized / 0 physical volume(s) not resized # lvextend -L8G /dev/template/root Extending logical volume root to 8.00 GiB Insufficient free space: 1630 extents needed, but only 0 available 2. http://blog.wpkg.org/2010/10/04/resizing-qcow2-images/ Result: OS system can't see the disk space My 3rd option is to install libguestfs-tools package, but I would like to avoid it since it's not part of Debian release. Any good step by step guide to enlarge a qcow2 + LVM virtual disk? Thanks
