Service VM may write 0x6 to port 0xcf9 to trigger a warm reset, but
current hypervisor always performs a cold reset by writing 0xE to CF9.
Hypervisor should reboot the system in the same mode as Service VM
specified. Specific OS features (like linux pstore) requires warm
reset to keep data across reboot.
The behavior of hv console's reboot command (cold reset) remains

After rebooting guest, CPPC initialization failed because _CST and _CPC
missed in DSDT table. When writing _CST and _CPC in DSDT table, it gets
cx_cnt or px_cnt as condition. Getting cx_cnt or px_cnt triggers
the hypercall hcall_get_cpu_pm_state. The hypercall hcall_get_cpu_pm_state
uses VM_CREATED as VM state's condition. While, after rebooting guest,
the VM state is VM_PAUSED when writing _CST and _CPC in DSDT table.
Therefore, changing VM state's condition from VM_CREATED to VM_CREATED or
VM_PAUSED for hcall_get_cpu_pm_state can solve the CPPC initialization
failed issue after rebooting guest.

This is implemented through two methods called updateSchema which is

while loading scenario.xml.
