Description of problem: If a Windows guest has bad sectors (eg. if it came from a physical machine) then virt-resize cannot resize it, because the ntfsresize utility will refuse to run unless the --bad-sectors option is specified. We should either detect and add this option automatically (if that is possible) or we should allow the user to specify this option. Version-Release number of selected component (if applicable): libguestfs 1.21 (Suggested by Eric Blake)
Or even find a way to teach windows that there are no longer any bad sectors in the copy (perhaps by clearing or deleting the hidden $BadClust file), since the destination file is not the same block device as the source that had bad clusters in the first place.
Looks like 'ntfsfix --clear-bad-sectors /dev/...' is the way to modify the file system to force windows to quit treating sectors as bad.
This product has been discontinued or is no longer tracked in Red Hat Bugzilla.
Reopening because Virtualization Tools has not been discontinued.
