Let us support the basic channel I/O passthrough infrastructure based on
vfio, which have been introduced in QEMU 2.10. The current focus is to
support dasd-eckd (cu_type/dev_type = 0x3990/0x3390) as the target
device.
There is a temporary delay with our mail reception. The answer to the
question below is as follows.
Quick question: Does "current focus" mean "we have only tested it with
ECKD DASD", or "we only allow passthrough of 3990/3390 devices"?
yes, it means we have only tested it with ECKD DASD device. The libvirt
implementation supports all the devices which are supported by QEMU.
Thanks.
