Enabling hardware virtualization support Habilitando el soporte de virtualización hardware
This section covers setting up `libvirt` on your system. After setting up `libvirt`, you can create virtualized guest operating systems, also known as virtual machines. Esta sección cubre el ajuste de `libvirt` en su sistema. Después de ajustar `libvirt`, usted puede crear sistemas operativos invitados virtualizados, también conocidos como máquinas virtuales.
System requirements
To run virtualization on Fedora, you need:
At least 600MB of hard disk storage per guest. A minimal command-line Fedora system requires 600MB of storage. Standard Fedora desktop guests require at least 3GB of space.
At least 256MB of RAM per guest, plus 256MB for the base operating system. At least 756MB is recommended for each guest of a modern operating system. A good way to estimate this is to think about how much memory is required for the operating system normally, and allocate that amount to the virtualized guest.
KVM requires a CPU with virtualization extensions, found on most consumer CPUs. These extensions are called Intel VT or AMD-V. To check whether you have CPU support, run the following command:
$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo
If this command results in nothing printed, your system does not support the relevant virtualization extensions. You can still use QEMU/KVM, but the emulator will fall back to software virtualization, which is much slower.
