./sysutils/xenkernel418, Xen 4.18.x Kernel

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 20241221, Package name: xenkernel418-20241221, Maintainer: bouyer

Xen is a hypervisor which supports running multiple guest operating
systems on a single machine. Guest OSes (also called "domains")
can be either paravirtualised (i.e. make hypercalls in order to
access hardware), run in HVM (Hardware Virtualisation Mode) where
they will be presented with virtual devices, or a combination where
they use hypercalls to access hardware but manage memory themselves.
At boot, the xen kernel is loaded 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 4.18 Xen kernel itself. PCI passthrough is
not supported. PAE is mandatory; on i386 one must use XEN3PAE_DOM[0U].

Log message:
Add xenkernel418 version 20231116
Unlike previous Xen packages, the xentools418 and xenkernel418 will point
to a specific commit of the stable branch (instead of release tags),
the package version being the date of the commit. Hopefully this will make
tracking security fixes easier.
