[Qemu-devel] [PATCH 1/1] hw/arm/virt: increase max SMP CPU support to 8 for ARM virt

[Wei Huang]

Current ARM virt model supports up to 4 CPUs. Given that many recent
ARM servers contain 8 or more cores, it is time to bump up max guest CPUs
to 8. This patch was tested with a VM runnng 3.15 Linux kernel. All 8
VCPUs showed up.
