Thanks for submitting.

I'm fine with the patch. But can you expand on what "pvscsi" is, what
advantages there is for an user to enable it, what hypervisors support
it, etc. Ideally this info would be in the Kconfig menu as well.

Hi,

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

config PVSCSI

depends on DRIVES && QEMU_HARDWARE

bool "pvscsi controllers"

default y

help

Support boot from Paravirtualized SCSI storage. This kind of storage

is mainly supported by VMware ESX hypervisor. It is commonly used

to allow fast storage access by communicating directly with the

underlying hypervisor. Enabling this type of boot will allow

booting directly from images that were imported from ESX platform,

without the need to use slower emulation of storage controllers

such as IDE.
