View source for QEMU

[https://wiki.qemu.org/Index.html QEMU] is a very flexible open source virtual machine and emulator. QEMU is able to virtualize or emulate x86, x86_64, PowerPC, ARM, and S390 guests.

= Install Alpine Linux in QEMU =
{{:Install_Alpine_in_QEMU}}

= Live mode =
{{:Running_Alpine_in_Qemu_Live_mode}}

= Advanced network configuration =

{{:Running Alpine Linux As a QEMU networked Guest}}

= Using Xorg inside QEMU =

The video driver needed for Xorg inside QEMU for Alpine 3.17 and older is {{ic|{{pkg|xf86-video-modesetting|branch=v3.17|arch=x86*}}}}. In newer releases of alpine, the driver is automatically pulled in as part of {{ic|setup-xorg-base}}.

{{tip|Probably for KVM/Qemu guests you want to use ''qxl'' Video and Display ''Spice''. For this purpose install xf86-video-qxl on guest and run a Spice client on the host}}

If you decided to use a ''qxl'' Video on KVM/Qemu guest, add this configuration to {{Path|/etc/X11/xorg.conf}}

{{Cat|/etc/X11/xorg.conf|Section "Device"
  Identifier "qxl"
  Driver "qxl"
  Option "ENABLE_SURFACES" "False"
EndSection}}

= Run a guest OS on Alpine Linux using KVM/QEMU =

Install:

{{Cmd|# apk add qemu-system-x86_64 qemu-modules libvirt libvirt-qemu}}

{{Note|also install {{Pkg|virt-manager}} for a KVM/QEMU gui}}

<br>

Add '''tun''' to {{Path|/etc/modules}}:

{{Cmd|# echo tun >> /etc/modules}}

<br>

Starting '''tun''' now:

{{Cmd|# modprobe tun}}

<br>

Add your user to the '''kvm''' and '''qemu''' groups

{{Cmd|# addgroup <username> kvm}}
{{Cmd|# adduser <username> qemu}}

Logout for the group changes to take effect
<!-- {{Cmd|qemu-system-x86_64 --enable-kvm -m 1024M -fda M6410220.IMG}} -->

<br>

Adding services:

{{Cmd|# rc-update add libvirtd}}
{{Cmd|# rc-update add libvirt-guests}}

Starting the services now:

{{Cmd|# rc-service libvirtd start}}
{{Cmd|# rc-service libvirt-guests start}}

<br>

If you are interested in using a bridged network (so that the guest machine can be reached easily from the outside), see [[Bridge]].
