[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
