Yes, the question is how you handle
I'm not sure I understand your question. In XenServer blktap2 we set CHS to
65535*16*255 in the VHD metadata for disks larger than 127GB. We don't really
care about these values, we just store them in the VHD metadata.

I would like to know what is done by other platforms. Stefano, any idea
about XenServer?
I am not sure, but maybe Thanos, that is working on
Ping?
Any thoughts on whether this is acceptable?

The VHD specification allows for up to a 2 TB disk size. The current
implementation in qemu emulates EIDE and ATA-2 hardware which only allows
for up to 127 GB. This disk size limitation can be overridden by allowing
up to 255 heads instead of the normal 4 bit limitation of 16. Doing so
allows
