Hi e100, thanks for reply.
"If your using raw" -> but I use ZFS.
My approach was, to add a second disk to the vm and then copy the first disc with clonezilla to an image on the 2nd disc.
But I would like to convert the VM to an raw image file with (for example)
qemu-img convert -f qcow2 kvm_source.img -O raw kvm_destination.img
But the disk is in local-zfs , I dont know how to access it. It seems to be a ZFS dataset.
