vTickSphere

os over x86 architecture, drive from one to one, lifting little by little.

bootloader stage1 & stage2 + kernel:
framework: 
  print, heap, paging, gdt, isr, task switch (within kernel for poc only),
  next: syscall(allow for user mode inject into kernel mode for the permission),
        user mode task creation then context switch from kernel->user->kernel...
        kernel/user mode permission isolation: paging for user and kernel mode, gdt for user code/data, kernel code/data.
        simple file system in disk and memory layout for the files structure.

To check exact port used by qemu process via netstat -lntup in server,
e.g
netstat -lntup
tcp        0      0 172.23.245.135:11801    0.0.0.0:*               LISTEN      1289/qemu-system-i3

Then in client as RealVNC Viewer, login via:
