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.
v2 - v3:
* Change the XML tag name to "cdbfilter"
* Maintain an internal list of shared disks for QEMU driver.
v3 - v4:
* Rebase on the top
* More testing
Patches 1/10 ~ 4/10 are to introduce the internal list for shared
disks.
Osier Yang (10):
qemu: Introduce a list to maintain the shared disks between domains
qemu: Init/Free the list with the driver's lifecyle
qemu: Add/remove the shared disk entry during domain's lifecyle
qemu: Add/Remove the entry of sharedDisks when live
attaching/detaching
docs: Add docs and rng schema for new XML cdbfilter
conf: Parse and format the new XML tag cdbfilter
util: Prepare helpers for unpriv_sgio setting
qemu: Manage disk's cdbfilter in domain's lifecycle
qemu: Do not restore the sysfs unpriv_sgio if the disk is being
shared
qemu: Error out when domain starting if the cdbfilter setting
conflicts
I missed patches to set/restore the disk's unpriv_sgio when attaching
and detaching, and one patch to reject attaching shared disk if it's
"cdbfilter" conflicts with others which are in use. But I run out of
time today, and it doesn't affect the reviewing of already post ones,
will post the missed patches tomorrow.
Regards,
Osier
