qemu: don't fail capabilities check on 0.12.x
Fixes regression introduced in commit 2211518, where all qemu 0.12.x fails to start, as does qemu 0.13.x lacking the pci-assign device. Prior to 2211518, the code was just ignoring a non-zero exit status from the qemu child, but the virCommand code checked this to avoid masking any other issues, which means the real bug of provoking non-zero exit status has been latent for a longer time. * src/qemu/qemu_capabilities.c (qemuCapsExtractVersionInfo): Check for -device driver,? support. (qemuCapsExtractDeviceStr): Avoid failure if all probed devices are unsupported. Reported by Ken Congyang.
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
