tkvm is a minimal VMM which can run a very simple VM and can run a whole operation system in the future. It uses KVM API to simulate a VM. It is a learning project contemporarly.
Learning of tkvm can be divided into 4 steps:
- Build a prototype of KVM API usage
- Accomplish the part of Memory set
- Accomplish the part of load kernel boot and initrd
- Accomplish the part of CPU
Run the tkvm and then run the command
./tkvm -kernel image/bzImage -initrd image/initramfs-busybox-x86.cpio.gz
Build your own Linux image
Notice: If you need to build the KVM acceleration kernel, change the command make kvmconfig to make kvm_guest.config. Reference: https://www.mail-archive.com/[email protected]/msg2140886.html
You may need to re-run the programme many time for successfully get the terminal. Only for x86 structure yet.
