-> Mainly thanks to the [porting](http://www.gnu.org/software/hurd/hurd/running/debian/porting.html)

+> This month Samuel Thibault [merged his development branch into GNU Mach's
+> master
+> branch](http://lists.gnu.org/archive/html/bug-hurd/2009-12/msg00058.html) --
+> meaning that his [[GNU Mach Xen domU
+> port|microkernel/mach/gnumach/ports/xen]] is now part of the official
+> sources. Only the [[microkernel (GNU Mach)|microkernel/mach/gnumach]] needed
+> to be extended, and no changes were needed in the Hurd, or glibc code bases.
+> He had started this port in 2007 already, but it has been in heavy use over
+> the last two years already, so merging it into the main source bases was long
+> overdue.
+
+> He also got the necessary Xen patches committed into Xen's unstable branch,
+> so that from Xen's 4.0 release on you'll be able to boot GNU/Hurd systems
+> using `pv-grub`, without the need to prepare a special bootstrap image (like
+> an initrd).
+
+> Of course, running GNU/Hurd systems in other virtualization environments is
+> possible too, but the Xen domU approach offers superior performance compared
+> to [[hurd/running/QEMU]]'s machine emulation, for example.
+
+> Samuel also spent some time on adding code for [detecting invalid (duplicate)
+> port
+> deallocations](http://lists.gnu.org/archive/html/commit-hurd/2009-12/msg00016.html),
+> and started fixing these, as well as he fulfilled his usual share of
+> miscellaneous bug fixing.

+> The [[open issues/DDE]] port of Zheng Da now [passes the first

+> overhead for maintaining them.
+
+> Thanks to the [[hurd/running/debian/porting]] work of mainly Emilio Pozuelo
+> Monfort and Pino Toscano, users of the Hurd can get many more packages
+> directly via the [[Debian GNU/Hurd|hurd/running/debian]] distribution.
