libxen-4.6: Public libs for Xen

 This package contains the shared toolstack libraries for Xen.

libxen-4.6-dbgsym: debug symbols for package libxen-4.6

 This package contains the shared toolstack libraries for Xen.

libxen-dev: Public headers and libs for Xen

 This package contains the public headers and static libraries for Xen.
 .
 The libxenlight library is intended as a common base for all Xen toolstack
 developers. The libxlutil library contains additional helpers which may
 be useful to toolstack developers.
 .
 The libxenstore library allows userspace processes to interact with the
 XenStore database. XenStore is a shared database used for interdomain
 communication of configuration and status information. It is accessible
 to all domains running on the same Xen host. See
 http://wiki.xen.org/wiki/XenStore for more information.
 .
 The libxenctrl and libxenguest libraries are internal libraries intended
 for use by the Xen toolstack and are not intended to be used directly.
 Toolstack authors should use libxenlight.

libxenstore3.0: Xenstore communications library for Xen

 This package contains the client library interface to XenStore. .

libxenstore3.0-dbgsym: debug symbols for package libxenstore3.0

 This package contains the client library interface to XenStore. .

xen-hypervisor-4.6-amd64: Xen Hypervisor on AMD64

 The hypervisor is the "core" for XEN itself. It gets booted by the boot
 loader and controls cpu and memory, sharing them between your
 administrative domain (Domain 0) and the virtual guest systems.
 .
 In order to boot a XEN system along with this package you also need a
 kernel specifically crafted to work as the Domain 0, mediating hardware
 access for XEN itself.

xen-hypervisor-4.6-arm64: Xen Hypervisor on ARM64

 The hypervisor is the "core" for XEN itself. It gets booted by the boot
 loader and controls cpu and memory, sharing them between your
 administrative domain (Domain 0) and the virtual guest systems.
 .
 In order to boot a XEN system along with this package you also need a

 access for XEN itself.

xen-hypervisor-4.6-armhf: Xen Hypervisor on ARMHF

 The hypervisor is the "core" for XEN itself. It gets booted by the boot
 loader and controls cpu and memory, sharing them between your
 administrative domain (Domain 0) and the virtual guest systems.
 .
 In order to boot a XEN system along with this package you also need a
 kernel specifically crafted to work as the Domain 0, mediating hardware
 access for XEN itself.

xen-system-amd64: Xen System on AMD64 (meta-package)

 This package depends on the latest Xen hypervisor for use on AMD64 and the
 Xen utils.

xen-system-arm64: Xen System on ARM64 (meta-package)

 This package depends on the latest Xen hypervisor for use on ARM64 and the
 Xen utils.

xen-system-armhf: Xen System on ARMHF (meta-package)

 This package depends on the latest Xen hypervisor for use on ARMHF and the
 Xen utils.

xen-utils-4.6: XEN administrative tools

 The userspace tools to manage a system virtualized through the XEN virtual
 machine monitor.

xen-utils-4.6-dbgsym: debug symbols for package xen-utils-4.6

 The userspace tools to manage a system virtualized through the XEN virtual
 machine monitor.

xen-utils-common: Xen administrative tools - common files

 The userspace tools to manage a system virtualized through the Xen virtual
 machine monitor.
 .
 This package is only required on the host system (Domain 0) and not on the
 virtual guest systems (Domain U).

xenstore-utils: Xenstore command line utilities for Xen

 This package contains command line utilities for interacting with
 XenStore.
 .
 XenStore is a shared database used for interdomain communication of
 configuration and status information. It is accessible to all domains
 running on the same Xen host. See http://wiki.xen.org/wiki/XenStore for
 more information.
 .
 In the common case these tools are used by the Xen toolstack running in
 domain0 (or a driver domain) however they may also be used in a guest
 domain to support local scripting which wants to communicate via XenStore.
