[Qemu-devel] Why is virt-resize designed to involve two disks?

[吴志勇]

HI,

As you've known, vhd-util and qemu-img both provide the capacity for resizing the original disk, but why is virt-resize designed to involve two disks, not only original disk? Is there any concern? Is it possible that only one original disk is involved in virt-resize?
