[Qemu-devel] [PATCH 2/2] spapr_cpu_core: migrate VPA related state

2018-06-18 Thread Greg Kurz
QEMU implements the "Shared Processor LPAR" (SPLPAR) option, which allows the hypervisor to time-slice a physical processor into multiple virtual processor. The intent is to allow more guests to run, and to optimize processor utilization. The guest OS can cede idle VCPUs, so that their processing
