Here, I am using Xen 4.4 with the xl toolstack on a Debain 8 Dom0, but can be adjusted as needed for older versions of Xen, or if using the xm toolstack.Įnable Operating System Fixup. This article looks at installing CentOS 7 (64-bit), but the process can be used for other OSes as well. Then, once installation is completed, we can convert the domain to boot via PyGrub so that it can benefit from the increased speed that comes with paravirtualization (PV) over full hardware virtualization (HVM). Here, we will look at installing an operating system on to a Xen domain by first creating an HVM-based domain which will run during our install of the OS. This works great for Debian, Ubuntu, and CentOS 5 - but other OSes takes a bit of work, or may not be easily possible without installation from its original media. With debootstrap, rinse, etc.) is not easy to accomplish. For many candidate DomU distributions, installation via the xen-tools xen-create-image (eg. To demonstrate, we setup a paravirtualized CentOS 7 (64-bit) domain. This article covers creating a DomU on Xen 4.4 by installation of an OS from its native install media (typically an ISO image), first as an HVM domain during installation, then converting to a PV domain after installation is complete.
