[Bug 814222] Re: kvm cannot use vhd files over 127GB

[Serge Hallyn]

Thanks for taking the time to submit this bug.

It looks like the 127G limit is known.  A recent patch went in to help
with the symptom you are seeing, but unfortunately it only makes the
failure detectable  :)  It's a start at least.

The following commit should be pulled in:

    block-vpc: Don't silently create smaller image than requested
    
    The algorithm from the VHD specification for CHS calculation silently limits
    images to 127 GB which may confuse a user who requested a larger image. Better
    output an error message and abort.
