<div>{{Hatnote|For the ARM port supporting paravirtualized guests on processors without the virtualization extensions see [[Xen ARM (PV)]].}}<br />
<br />
The ARM v7-A architecture includes the optional virtualization extensions that allow a hypervisor to manage fully hardware virtualized guests. These extensions are available in the ARM Cortex A15 and Cortex A7 processors.<br />
<br />
== Requirements ==<br />
<br />
;Real-time System Model<br />
:Either the v7-A Envelope Model or the Cortex A15/A7 models (single CPU only).<br />
;Xen<br />
:arm-v4 branch of [http://xenbits.xen.org/gitweb/?p=people/sstabellini/xen-unstable.git/.git;a=summary git://xenbits.xen.org/people/sstabellini/xen-unstable.git/.git]<br />
;Linux kernel for dom0<br />
:vexpress-dt branch of [http://xenbits.xen.org/gitweb/?p=people/dvrabel/linux.git;a=summary git://xenbits.xen.org/people/dvrabel/linux.git]<br />
;dom0 userspace<br />
:(more details here)<br />
<br />
== Dom0 kernel ==<br />
<br />
Enable at least ARCH_VEXPRESS, ARCH_VEXPRESS_DT, ARM_APPENDED_DTB and ARM_ATAG_DTB_COMPAT. Disable SPARSE_IRQ (it doesn't play nicely with device tree support).<br />
<br />
A working configuration is available [http://xenbits.xen.org/people/dvrabel/xen-arm/vexpress-dt.config here].<br />
<br />
=== Device Tree Blob (DTB) ===<br />
<br />
Build the device tree blobs (flattened device tree binary files) with <tt>make dtbs</tt>. A suitable DTB file for the envelope model is vexpress-v2p-aem-v7a.dtb.<br />
<br />
=== Flash Image ===<br />
<br />
The dom0 kernel is loaded by Xen from the beginning of the flash. The kernel zImage and the DTB should be appended. e.g., <tt>cat zImage vexpress-v2p-aem-v7a.dtb &gt; flash.bin</tt>.<br />
<br />
=== Native boot ===<br />
<br />
To boot the kernel natively use an updated boot-wrapper from [http://xenbits.xen.org/gitweb/?p=people/dvrabel/boot-wrapper.git;a=summary git://xenbits.xen.org/people/dvrabel/boot-wrapper.git].<br />

__NOTOC__<br />
XenSource, Inc. developed enterprise-grade virtualization solutions based on the industries best server virtualization technology, the Open Source Xen hypervisor. Founded and run by the original Xen development team, [[XenSource]] products will allow enterprises to realize the TCO savings that result from server consolidation, increased utilization, and reduced complexity in the datacenter.<br />
<br />
XenSource was acquired by Citrix in 2007.<br />
<br />
The XenSource name has been retained as a string in the paths of several XenServer/XCP components, for example /etc/xensource, /opt/xensource, /var/log/xensource.log and so on.<br />
