How to use QEMU
QEMU is a very flexible virtualization technology however it is quite slow and it is recommended that you understand and evaluate alternative solutions before picking this one. Refer to https://fedoraproject.org/wiki/Getting_started_with_virtualization[Getting started with virtualization]
QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation.
QEMU has two operating modes:
Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code.
User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU.
QEMU is available on Fedora repository. It can be installed by using https://fedoraproject.org/wiki/dnf[DNF]:
$ su -c "dnf install qemu"
