Subject: [Qemu-devel] Question about maximum disk size of a dynamic hard disk

Hello Kevin, Stefan and all

There is a sentence "The maximum size of a dynamic hard disk is 2040 GB.
The actual size is restricted by the underlying disk hardware protocol. For
example,
ATA hard disks have a 127-GB limit" in VHD specification. This limitation
infected the
algorithm of block/vpc.c:calculate_geometry(). However, SATA disk is used
to
replace traditional IDE disk now. I am wondering whether is possible to
support that
VHD is bigger than 127-GB(SATA disk underlying)??

Thanks

Mitnick
