Dear all,
I am very interested in KVM design and trying to figure out the boot
process of guest VM. According to my understanding about QEMU code, bochs BIOS
is loaded into memory by pc_system_firmware_init(…). However, I notice QEMU
handles hardware initialization, allocates memory and stores user's
configuration in fw_cfg. In addition, QEMU loads linux by load_linux(…). Then
my question is what does bochs BIOS do during the period guest VM boots. Based
on my understanding, QEMU has already finished many works belong to BIOS, why
does QEMU load BIOS into memory?
I will really appreciate any comments and help.
Thank you very much,
Best Regards,
