There are 5 versions of xen in pkgsrc, which is confusing. Explain in DESCR which version is in which package (xenkernel3 contains 3.1), and which versions support PCI passthrough (only 3.1). Explain which versions support non-PAE (3.1) and PAE (3.3, 4.1, 4.2), because the HOWTO is out of date and it's easy to end up with a non-working system on a 3.1 to 3.3 update. Cuation that 2.0 is beyond crufty. This is a DESCR-only change (with PKGREVISION++ of course). (ok during freeze agc@)

Xen is a virtual machine monitor for x86 hardware (runs only on
|
|
i686-class CPUs), which supports running multiple guests operating
|
|
systems on a single machine. Guest OSes (also called "domains")
|
|
require a modified kernel which supports Xen hypercalls in replacement
|
|
to access to the physical hardware. At boot, the xen kernel is loaded
|
|
(via grub) along with the guest kernel for the first domain (called
|
|
domain0). domain0 has privileges to access the physical hardware (PCI
|
|
and ISA devices), administrate other domains and provide virtual
|
|
devices (disks and network) to other domains.
|
|
|
|
This package contains the 3.3 Xen3 kernel itself. PCI passthrough is
|
|
not supported. PAE is mandatory; on i386 one must use XEN3PAE_DOM[0U].
|
|
3.3 is no longer maintained upstream.
