Re: [Libguestfs] [PATCH FOR DISCUSSION ONLY] virt-resize tool for resizing virtual machines.

That probably makes things a lot easier :) If the user wants to expand an image, then simply resize the partition and run pvextend. Or alternatively add a new partition, run pvcreate and add it to the volume group. If a user wants to shrink an image, he simply needs to ensure enough free space is available within the VG for the virt-resize operation to succeed. The only use case that causes problems is if the user has all VG space consumed by filesystems that cannot be unmounted for shrinking the filesystem (read: root). But in that case there is little point in using LVM anyway :) I'd say that resizing LV's and their filesystems too is a 'nice to have' feature, but not absolutely required (in most cases anyway). This is all just my opinion of course :) -- Dennis Krul <dennis(a)tilaa.nl&gt;
