As a result of CVE-2011-4127, libvirt disabled generic SCSI
|
||
|
|
commands passed through to the underlying disk by qemu
|
||
|
|
from a guest to a virtio disk when device type is "disk"
|
||
|
|
afer commit 177db087757e4adb02c211de56336a5991c8eb20.
|
||
|
|
And libvirt introduce a new device type "lun"
|
||
|
|
to allow SG_IO commands passing through.
|
||
|
|
This patch allows VM admin to configure this via virt-manager.
