9c14a9abintroduced vzNewDomain function to enlist libvirt domain object before actually creating vz sdk domain. Fix should fix race on same vz sdk domain added event where libvirt domain object is enlisted too. But latereb5e9c1eadded locked checks for adding livirtd domain object to list on vz sdk domain added event. Thus now approach of9c14a9abis unnecessary complicated. See we have otherwise unuseful prlsdkGetDomainIds function only to create minimal domain definition to create libvirt domain object. Also vzNewDomain is difficult to use as it creates partially constructed domain object. Let's move back to original approach where prlsdkLoadDomain do all the necessary job. Another benefit is that we can now take driver lock for bare minimum and in single place. Reducing locking time have small disadvatage of double parsing on race conditions which is typical if domain is added thru vz driver. Well we have this double parse inevitably with current vz sdk api on any domain updates so i would not take it here seriously. Performance events subscribtion is done before locked check and therefore could be done twice on races but this is not the problem. Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy@virtuozzo.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
