qemu: Avoid assigning unavailable migration ports
https://bugzilla.redhat.com/show_bug.cgi?id=1019053 When we migrate vms concurrently, there's a chance that libvirtd on destination assigns the same port for different migrations, which will lead to migration failure during prepare phase on destination. So we use virPortAllocator here to solve the problem. Signed-off-by: Wang Yufei <james.wangyufei@huawei.com> Signed-off-by: Jiri Denemark <jdenemar@redhat.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. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
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
Hypervisor.
