QEMU vs Virtualbox

항상 가지고 있던 궁금증. 어느것을 쓰는 것이 나은가...

여기 잘 정리된 내용이 있어서 퍼 온다. 결론은 일반적으로 dual booting 이 싫고 두가지 이상의 OS 를 실질적으로 사용하고 싶은 경우라면 Virtualbox. QEMU 는 kernel development 등을 하는 사람한테 필요??

About VirtualBox

1. User friendly.
2. VirtualBox supports only x86/x64 processor architecture.
3. VirtualBox is fast and generates less CPU load
4. VirtualBox is for users who want to try out an OS or who want avoid the hassle of dualbooting
5. VirtualBox uses some parts of the QEMU project.
6. VirtualBox relies on Intel VT-x/AMD-V for acceleration
7. Supports latest virtual hardware and obselete virtual hardware.Support for USB 3.0 is present in virtual machine

About QEMU

1. Not so user friendly
2. QEMU supports  wide range of processor architectures like ARM,MIPS,PowerPC,SPARC,Alpha ,etc.,
3. QEMU is damn slower.
4. QEMU is for OS kernel developers and advanced users.
5. QEMU is a bit older project than VirtualBox
6. QEMU uses KVM for acceleration ( KVM can be utilized only in Linux !  )
7. Virtual hardware support is limited, no USB 3.0 in virtual machine ,etc.,

and many more !

I strongly recommend VirtualBox if you are not into OS kernel development !
