We don't really care about these values, we just store them in the VHD metadata. > -----Original Message----- > From: Paolo Bonzini [mailto:pbonzini@xxxxxxxxxx] > Sent: 14 November 2012 16:36 > To: Thanos Makatos > Cc: Stefano Stabellini; Charles Arnold; qemu-devel@xxxxxxxxxx; Kevin > Wolf; stefanha@xxxxxxxxxx; xen-devel@xxxxxxxxxxxxxxxxxxx > Subject: Re: [PATCH] block: vpc support for ~2 TB disks > > Il 14/11/2012 17:25, Thanos Makatos ha scritto: > > We don't use qemu's VHD driver in XenServer.
