=================== (VII) Commands Used =================== A. Qemu launch commands to init the machine (with 6 possible vCPUs): $ qemu-system-aarch64 --enable-kvm -machine virt,gic-version=3 \ -cpu host -smp cpus=4,disabled=2 \ -m 300M \ -kernel Image \ -initrd rootfs.cpio.gz \ -append "console=ttyAMA0 root=/dev/ram rdinit=/init maxcpus=2 acpi=force" \ -nographic \ -bios QEMU_EFI.fd \
The parameter 'disabled=2' isn't correct here and it needs to be 'disabledcpus=2'. Otherwise, the VM won't be started due to the unrecognized parameter. $ /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \ --enable-kvm -machine virt,gic-version=3 -cpu host,sve=off \ -smp cpus=4,disabled=2 -m 1024M \ -kernel /home/gavin/sandbox/linux.guest/arch/arm64/boot/Image \ -initrd /home/gavin/sandbox/images/rootfs.cpio.xz -nographic qemu-system-aarch64: Parameter 'smp.disabled' is unexpected Thanks, Gavin
