To do this a new bootloader entry is needed. The boot loader must be modified to load a special Xen kernel ( xen.gz or in the case of UEFI xen.efi) which is then used to boot the normal kernel. Make sure you have a alternative way to boot your system like a USB stick or other livemedia BEFORE you make changes to your boot system. This might be the most common error new as well as old users do. Warning: Never assume your system will boot after changes to the boot system. If you choose to build stubdom support, a xen-stubdom package will be built. Xen-docs AUR will be also built for the man pages and documentation. $ build_stubdom=true efi_dir='/boot/EFI' makepkg Pass these arguments to makepkg as variables:

efi_dir, efi_mountpoint - Your EFI directory and mountpoint.

Components for stubdom are broken off into xen-stubdom if built.

build_stubdom - Build the components to run Xen stubdoms, mainly for dom0 disaggregation.

When building Xen, there are environmental variables that can be passed to makepkg. It is recommended that xen and its components are built in a clean environment, either in a VM or a chroot.

To boot VM-local kernels inside of a PVH VM, install xen-pvhgrub AUR. To run most VMs, you will also need to install xen-qemu AUR.įor BIOS support in VMs, install seabios. It provides the Xen hypervisor, current xl interface and all configuration and support files, including systemd services. To install the Xen hypervisor, install the xen AUR package.

In order to use PCI passthrough, the CPU must support IOMMU/VT-d. The Xen hypervisor also supports PCI passthrough where PCI devices can be passed directly to the domU even in the absence of dom0 support for the device. If such an option exists and is disabled, then enable it, boot the system and repeat the above command. If you believe the CPU supports one of these features you should access the host system's BIOS configuration menu during the boot process and look if options related to virtualization support have been disabled. If the above command does not produce output, then hardware virtualization support is unavailable and your hardware is unable to run HVM domU (or you are already running the Xen hypervisor). $ grep -E '(vmx|svm)' -color=always /proc/cpuinfo In order to verify this, run the following command when the Xen hypervisor is not running: To run HVM domU, the physical hardware must have either Intel VT-x or AMD-V (SVM) virtualization support. The Xen hypervisor requires kernel level support which is included in recent Linux kernels and is built into the linux and linux-lts Arch kernel packages.

Warning: Do not run other virtualization software such as VirtualBox when running Xen hypervisor, it might hang your system. If you are building a new host from scratch, see the Installation guide for instructions on installing Arch Linux. This installation can be a minimal install with only the base package and does not require a Desktop environment or even Xorg.

Before attempting to install the Xen hypervisor, the host machine should have a fully operational and up-to-date install of Arch Linux.

The Xen hypervisor relies on a full install of the base operating system. For the domU, Xen supports paravirtualized (PV) domains, hardware virtualized domains (HVM), and paravirtualised domains inside a hardware virtualiztion wrapper (PVH). Once the dom0 has started, one or more domU (short for user domains, sometimes called VMs or guests) can be started and controlled from the dom0. Once the hypervisor is loaded, it starts the dom0 (short for 'domain 0', sometimes called the host or privileged domain) which in our case runs Arch Linux. The hypervisor is started by the boot loader of the computer it is installed on. The Xen hypervisor is a thin layer of software which emulates a computer architecture allowing multiple operating systems to run simultaneously. Xen is the only type-1 hypervisor that is available as open source. Xen is an open-source type-1 or baremetal hypervisor, which makes it possible to run many instances of an operating system or indeed different operating systems in parallel on a single machine (or host). Reason: The sections need better structuring.
