It seems that this pr failed some x86_64 ci tests. We have set two build-only tests for platform nuc14mnk and ecx-2300f-peg, which you only have to pass compilation. But for qemu, we also setup tests to run zone0 Linux and zone1 Linux. You can refer to configs in |

- Add mb2_boot.S bootloader for 16-bit to 32-bit mode transition - Bootloader sets up GDT with TSS and jumps to kernel entry - Pass kernel entry via ESI to bootloader on VM entry - Add multiboot_info_paddr/multiboot_enabled to HvArchZoneConfig - Remove unused print_memory_map - Add v_bus/v_device/v_function to HvPciDevConfig - Define MULTIBOOT2_MAGIC constant
- Multiboot2 boot protocol: mb2_boot.S trampoline, VMCS register setup, kernel-side Multiboot2 info construction in boot.rs - Adjust zone1 reserved memory size for Asterinas coexistence - Add virtio_cfg_asterinas.json example config Related hvisor-tool changes (raw cmdline loading, initramfs sizing) live in hvisor-tool/ and will follow as a separate PR.
Selectively intercept and forward timer-related x2APIC MSRs, validate LVT_TIMER and DIV_CONF writes, inject #GP on invalid WRMSR values, and keep TPR/TMR/CMCI on the pass-through path. The guest timer vector is also protected from the keyboard vector handling so Asterinas timer interrupts are delivered.
Use the OSDK-style init command line with init=/init -- sh -l so zone1 automatically runs the initramfs /init script and enters a shell. The -- separator prevents kernel parameters from being treated as init program arguments.

Two commits adding Asterinas guest support on x86_64 QEMU:
Related hvisor-tool changes (load raw cmdline, initramfs sizing) are in this repo's hvisor-tool/ and will follow as a separate PR against the tooling repository.
