Re: [PATCH 0/6] qemu: Fix cdrom as SCSI hostdev via -blockdev

use 'host_cdrom' when using blockdev explicitly. Fix the hostdev code
which was recently converted to -blockdev.
Warning:
I _don't_ have a box with a CDROM handy so this code is not tested in action!
I've tried this a bit more in a virtual environment ...
Peter Krempa (6):
qemuProcessCreatePretendCmd: Split up preparation and command building
qemu: hostdev: Prepare definition bits in qemuDomainPrepareHostdev
qemu: Prepare hostdev data which depends on the host state separately
qemuxml2argvmock: Remove mocking of 'virSCSIDeviceGetSgName'
These above are pure refactors which are IMO worth keeping, so somebody,
please review.
qemu: Detect whether a SCSI hostdev is a cdrom
qemu: Add test cases for 'host_cdrom' blockdev backend via <disk>
(self) NACK to those above 'host_cdrom' doesn't work with /dev/sg* as it
doesn't detect that its a generic device for passthrough. Using
'host_device' is needed here, so the code we have currently is correct.
I've tried this in nested virtual environment and the passthrough works
fine for me.
daggs,
I need to start over, could you please post the following info. (please
gather it again, so that it's all consistent):
host OS side:
libvirt version
lsblk
lsscsi
VM XML file
VM command line
guest OS side:
lsblk
lsscsi
lspci
thanks!
