Previously the VM kernel bootargs for pre-launched VMs and direct boot mode of SOS VM are built-in hypervisor binary so end users have no way to change it. Now we provide another option that the multiboot module string could be used as bootargs also. This would bring convenience to end users when they use GRUB as bootloader because the bootargs could be configurable in GRUB menu. The usage is if there is any string follows configured kernel_mod_tag in module string, the string will be used as new kernel bootargs instead of built-in kernel bootargs. If there is no string follows kernel_mod_tag, then the built-in bootargs will be the default kernel bootargs. Please note kernel_mod_tag must be the first word in module string in any case, it is used to specify the module for which VM.
