v3:
- included commit "Hot add/remove CPUs on PPC"
v2:
- patch rebased
This patchset refactors part of the code related to updating VM CPUs.
I am aware of two tests which are failing with this patchset. They'll be worked
on before the final version.
Crístian Deives (4):
Use locks to prevent concurrent updates to VMs
Update VCPU by using libvirt function
Set max VCPU count to the max supported value
Check if the VM update params are valid for the current state

New subject: [PATCH v3 1/5] Use locks to prevent concurrent updates to VMs
From: Crístian Deives <cristiandeives(a)gmail.com>
If several users try to update the same VM at the same time, an error
may happen due to concurrent access.
Define a dictionary containing one lock per each VM, and use it when
updating the VM: the lock is acquired before the update operation begins
and it is released when the operation finishes (whether by success or
failure).

New subject: [PATCH v3 2/5] Update VCPU by using libvirt function
From: Crístian Deives <cristiandeives(a)gmail.com>
Currently, the VCPU count is updated by editing the configuration XML
(tag: <vcpu>). However, in some cases, editing that tag will only update
the maximum VCPU count, not the current one. For example, if the VM has
the following XML tag:
<vcpu current='2'>8</vcpu>
and the user updates the VCPU value to 10, Kimchi will update the XML
tag to:
<vcpu current='2'>10</vcpu>
which is probably not what the user wanted.
Use the libvirt function "setVcpusFlags" to update the current and the
maximum VCPU values to the one specified by the user.

New subject: [PATCH v3 3/5] Set max VCPU count to the max supported value
From: Crístian Deives <cristiandeives(a)gmail.com>
When updating the CPU count of a VM, its maximum CPU count is also
updated to the same value. This wouldn't allow for CPU hotplug
afterwards.
Update the maximum CPU count to the maximum value supported by libvirt
when the user updates the VM CPU count.

Hi Ziviani, some considerations:
This patch set has some runtime problems, which you fix in your previous
patch set:
[Kimchi-devel] [PATCH v2 0/2] Improve VCPU code
I am against of commit this patch set and then commit another over it,
to fix the problems.
I would like to propose to you to merge both patch sets and separate in
less commits.
Will be better to review and test.
