openvz: Handle domain obj hash map errors
This makes the driver fail with a clear error message in case of UUID collisions (for example if somebody copied a container configuration without updating the UUID) and also raises an error on other hash map failures. OpenVZ itself doesn't complain about duplicate UUIDs since this parameter is only used by libvirt. (cherry picked from commit 31351c316fee0487dcbc5ef6b630d75be6b212e5)

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.

Description

virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
