[PATCH 00/16] Xen: remove xend config version

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

Ian Campbell recently attempted [1] to fix and issue around MAX_VIRT_VPUS
on ARM that required adding a new XEND_CONFIG_VERSION. After some
discussion [2] we decided to drop support for all of the old xend config
versions and go with the version supported in Xen 4.0, since the xl syntax
was originally based on (and intended to be compatible with) xm circa that
point in time.

This series removes all traces of xend config version from the codebase,
essentially removing support for Xen 3.x. Hopefully I succeeding in making
the rather large series reviewable. The series is also available on the
remove-xend-config-version branch of my libvirt github clone [2].
