This part contains some small fix and Implement the hot-plug/hot-unplug
and cold-plug/cold-unplug for Inter-VM Shared Memory PCI device.
Luyao Huang (10):
qemu: auto assign pci address for shared memory device
qemu: always build id when generate shared memory device CLI
qemu: Refactor creation of shared memory device commandline
conf: use virDomainChrSourceDef to save the path
conf:audit: introduce audit function for shared memory device
conf: Add helpers to insert/remove/find shmem devices in domain def
qemu: Implement shared memory device cold (un)plug
qemu: Implement share memory device hot-plug
qemu: Implement shared memory device hot-unplug
qemu: report error when shmem have a invalid address

New subject: [libvirt] [PATCH 01/10] qemu: auto assign pci address for shared memory device
Shared memory device is base on PCI address, even we do not
pass the pci address to qemu, qemu will auto assign a pci
address for it.

Got it, and i will split them to two lines in next version.

New subject: [libvirt] [PATCH 03/10] qemu: Refactor creation of shared memory device commandline
Rename qemuBuildShmemDevCmd to qemuBuildShmemDevStr and change the
return type so that it can be reused in the device hotplug code later.
And split the chardev creation part in a new function
qemuBuildShmemBackendStr for reused in the device hotplug code later.

You should be able to just unconditionally do
return virBufferContentAndReset() here since it returns NULL if
there's a buf->error.
ACK with that changed.
Right, i forgot that, thanks a lot for your review

Sorry, you cannot, there's a "goto error;" from some part of the code
where there is no buf->error set, so no change to this, you were
right.
No need to resend these first three, I'll push whatever is OK to go in
after I finish the review, and let you know what needs work.
Thanks,
Martin

I think that you shouldn't be able to have two <shmem/> elements in
the same domain, and since the name is mandatory, STREQ() should be
enough to check whether you need to return current 'i'.
Well, depending on whether you are unplugging it (you want everything
that was specified to match) or plugging it in (if there's the same
name, just reject it).

I think that you shouldn't be able to have two <shmem/> elements in
the same domain, and since the name is mandatory, STREQ() should be
enough to check whether you need to return current 'i'.
Okay, i agree use STREQ() instead of STRNEQ_NULLABLE. BTW I think one
guest could have more than one <shmem/> element, maybe one is non-server
shmem and another is server shmem, it depends on how to use it.
Well, depending on whether you are unplugging it (you want
everything
that was specified to match) or plugging it in (if there's the same
name, just reject it).
Okay, we could just check the name if use the same shmem (both server
and non-server) in the same guest is a invalid case.
Thanks a lot for your review.

Okay, i agree use STREQ() instead of STRNEQ_NULLABLE. BTW I think one
guest could have more than one <shmem/> element, maybe one is
non-server shmem and another is server shmem, it depends on how to use
it.
Maybe this function could have a bool parameter (something like a
'full_match') that would say whether everything must match or the name
is enough. And it the bool is false, streq is enough, but if it's
true, you could abstract the internals of this for body into
virDomainShmemEquals() or something and that would be called instead.

Good idea, this way is okay to me.
