I need to extend the root partition of a virtual machine (VM) using LVM (Logical Volume Manager) . I can afford a few minutes of downtime so a VM shutdown/reboot is fine.
The virtual hard disk is in qcow2 format but I can translate it to a raw format easily if it helps.
Search engines (read: google) did not help that much because answers usually refer to using a LVM partition to host the virtual hard disk, here the LVM partition is inside the virtual hard disk which is a simple file...
The virtual machine is running with linux-kvm and must stay bootable after the operation.
Thanks for any hints.
