Original name of series was:
Subject: [PATCH 0/3] make virDomainObjGetPersistentDef return only persistent definition
Changes from version1
=====================
Original motivation of the series was fixing virDomainObjGetPersistentDef so
that it would not return configs other than persistent. However the final patch
that does it in the first version is absent in current version. I think the
fix should be done another way and in different series. Thus this version has
only misc cleanups which are better splitted into patches in this version.
A few words why I leave patch for virDomainObjGetPersistentDef. First I should
not return NULL from the function as this value already has different meaning
- memory allocation error and there is code that checks for this error. This
code calls virDomainObjGetPersistentDef unconditionally but later use the
return value only for persistent domains, thus it could get NULL pointer on
function call and treat it as an allocation error.
I think the proper way would be chaning virDomainObjGetPersistentDef so it
could not fail that is not call virDomainObjSetDefTransient. Looks like this
is already true because drivers that distiguish between running/persistent
config call virDomainObjSetDefTransient ealy in the domain start process (and
even two times) so that later calls for virDomainObjSetDefTransient are
unnecessary.

ACK - I've adjusted the commit message mainly to give some more context
and pushed this patch.

New subject: [libvirt] [PATCH v2 2/4] libxlDomainSetMemoryFlags : reuse virDomainLiveConfigHelperMethod
Flag expansion is the same as in virDomainObjUpdateModificationImpact
which virDomainLiveConfigHelperMethod calls internally. The difference
is merely in implementation. Original code don't use mask
and handle case when VIR_DOMAIN_MEM_MAXIMUM is set explicitly.
Other parts are no different.

The change looks good to me. In fact, it seems to be an improvement over the
existing logic. ACK.

New subject: [libvirt] [PATCH v2 3/4] lxc, libxl: reuse virDomainObjUpdateModificationImpact
First fortunately all versions of *_CURRENT, *_CONFIG and *_LIVE flags
are numerically equal. Second libxl functions that don't use masks
for flag expansion forbid extra flags via virCheckFlags before.

This should be two separate patches and use of singular libxl: and lxc:
prefixes on the subject line.
#1 For libxl driver changes (there's a bug there too)
#2 for lxc changes
This one I'll ask you to fix the bug and repost as two separate patches
OK. I'll resend soon.

Please, disregard this. It's version of the other 1/4 patch which differs only in
commit message.
