Sorry for the duplicate posts. But I'm wondering why the
mail system delay the posting such long.

Hi,
As a result of RFC [1], this implements the unprivleged SG_IO
support. Testing is not that enough, but I'd like see the
reviewing earlier, and meanwhile I'm not going to give up
the further testing.
v4 - v5 (5 new patches):
* Set sysfs unpriv_sgio when attaching disk
* Restore sysfs unpriv_sgio when detaching disk
* Error out when attaching disk if it's shared by other
(domains), and the disk conf conflicts.
* Do not restore sysfs unpriv_sgio when detaching disk
if the disk is still being used by other domain(s)
* Dump the original unpriv_sgio state in status XML,
so that it won't be lost after restarting or reloading
libvirtd.
v3 - v4:
* Rebase on the top
* More testing
v2 - v3:
* Change the XML tag name to "cdbfilter"
* Maintain an internal list of shared disks for QEMU driver.
Patches 1/10 ~ 4/10 are to introduce the internal list for shared
disks.
