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

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
