Subject: qemu needs target kernel sets CONFIG_SCSI_VIRTIO=y to boot vmdk qcow2 and vdi
Date: Thu, 25 Feb 2016 18:36:21 +0800 [thread overview]
Message-ID: <56CED925.5090700@windriver.com> (raw)
Hi Bruce and Darren,
We need enable target kernel's CONFIG_SCSI_VIRTIO=y to make native qemu
can boot hdddirect, vmdk, qcow2 and vdi, otherwise, the scsi drive can't
work in qemu since our vm image's root default to /dev/sda2, or we can
change it default to /dev/hda2, then we don't have to make any changes
on kernel, but I prefer scsi since ide is going to be out of date.
I've tried to enable it by menuconfig, it works well, would you please
enable it by default ?

It nearly has no impact on the size.
