Xen Tools Versions Save

xen-tools 4.8 is primarily a maintenance release which adds support for more recent Debian and Ubuntu releases as DomU as well as Dom0.

It though also adds a bunch of additions like ZFS and LVM Thin Provisioning support contributed by multiple 3rd party contributors via pull requests. (Thanks!)

New Features

• Support for ZFS volumes (by Marc Bigler, GH #50)
• Support for LVM thin provisioning (by Nico Boehr, GH #47)
• Support for really random MAC addresses upon every xen-create-image invocation by using the new option --randommac. (by Pietro Stäheli, closes Debian bug report #855703)
• distributions.conf now supports arbitrary keyring files in /usr/share/keyrings/. (Needed for some EoL Ubuntu releases.)
• Support for netplan.io network configuration as used in recent Ubuntu releases. (Hook by Arno and Peter, GH #51)

Bug Fixes

• Minor documentation fixes.
• Eliminate progress reporting which is useless in logs. (Yuri Sakhno, GH #42)
• Drop pygrub path detection from xm.tmpl, Xen prefers a path-less bootloader='pygrub'.

Distribution Releases Changes

• Support for
  • Ubuntu 17.10 Artful Aardvark
  • Ubuntu 18.04 Bionic Beaver (LTS) (GH #51)
  • Ubuntu 18.10 Cosmic Cuttlefish
• Preliminary support for Ubuntu 19.04 Disco Dingo
• Knows about code name for Debian 12 (Bookworm).
• Considers Ubuntu Yakkety, Zesty and Artful being EoL.
• Set Ubuntu fallback suite to the latest LTS, i.e. 18.04 Bionic.

Other Changes

• Change all occurrences of httpredir.debian.org to deb.debian.org except those for the debian-archive. The latter now point to archive.debian.org directly.
• Many improvements for the release-testing script.
• Only run xen-toolstack helper script if both, xm and xl are present. Avoids warning about deprecated helper script.
