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.
Osier Yang (15):
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
qemu: Set unpriv_sgio when attaching disk
qemu: Restore unpriv_sgio when detaching disk
qemu: Error out if the shared disk conf conflicts with others when
attaching
