I was thinking about writing similar to this in the Kconfig help item. What
do you think ?
If this is ok I will resend the patch
depends on DRIVES && QEMU_HARDWARE
bool "pvscsi controllers"
Support boot from Paravirtualized SCSI storage. This kind of
is mainly supported by VMware ESX hypervisor. It is commonly

underlying hypervisor. Enabling this type of boot will allow
booting directly from images that were imported from ESX
without the need to use slower emulation of storage controllers
such as IDE.
