examples/vm_power_manager: fix libvirt dependency check
vm_power_manager utilize libvirt API virDomainGetVcpuPinInfo to retrieve domU vcpu information. This API is implemented from version 0.9.3. Suse11 SP3 32bit default libvirt version is 0.8.8. examples/vm_power_manager/channel_manager.c: channel_manager.c:117:3: error: implicit declaration of function 'virDomainGetVcpuPinInfo' Check and skip it from examples or raise an error when trying to compile without libvirt or with a too old libvirt. Fixes: e8ae9b662 ("examples/vm_power: channel manager and monitor in host") Signed-off-by: Marvin Liu <yong.liu@intel.com> Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
