- The QA scripts now depend on Python 2.5 or above
+Version 2.5.1
+-------------
+
+*(Released Fri, 11 May 2012)*
+
+A small bugfix release.
+
+The main issues solved are on the topic of compatibility with newer LVM
+releases:
+
+- fixed parsing of ``lv_attr`` field
+- adapted to new ``vgreduce --removemissing`` behaviour where sometimes
+ the ``--force`` flag is needed
+
+Also on the topic of compatibility, ``tools/lvmstrap`` has been changed
+to accept kernel 3.x too (was hardcoded to 2.6.*).
+
+A regression present in 2.5.0 that broke handling (in the gnt-* scripts)
+of hook results and that also made display of other errors suboptimal
+was fixed; the code behaves now like 2.4 and earlier.
+
+Another change in 2.5, the cleanup of the OS scripts environment, is too
+aggressive: it removed even the ``PATH`` variable, which requires the OS
+scripts to *always* need to export it. Since this is a bit too strict,
+we now export a minimal PATH, the same that we export for hooks.
+
+The fix for issue 201 (Preserve bridge MTU in KVM ifup script) was
+integrated into this release.
+
+Finally, a few other miscellaneous changes were done (no new features,
+just small improvements):
+
+- Fix ``gnt-group --help`` display
+- Fix hardcoded Xen kernel path
+- Fix grow-disk handling of invalid units
+- Update synopsis for ``gnt-cluster repair-disk-sizes``
+- Accept both PUT and POST in noded (makes future upgrade to 2.6 easier)

+.. admonition:: Bridging issues with certain kernels
+
+ Some kernel versions (e.g. 2.6.32) have an issue where the bridge
+ will automatically change its ``MAC`` address to the lower-numbered
+ slave on port addition and removal. This means that, depending on
+ the ``MAC`` address of the actual NIC on the node and the addresses
+ of the instances, it could be that starting, stopping or migrating
+ instances will lead to timeouts due to the address of the bridge
+ (and thus node itself) changing.
+
+ To prevent this, it's enough to set the bridge manually to a
+ specific ``MAC`` address, which will disable this automatic address
+ change. In Debian, this can be done as follows in the bridge
+ configuration snippet::
+
+ up ip link set addr $(cat /sys/class/net/$IFACE/address) dev $IFACE
+
+ which will "set" the bridge address to the initial one, disallowing
+ changes.
+
.. admonition:: Bridging under Debian
The recommended way to configure the Xen bridge is to edit your
bridge_ports eth0
bridge_stp off
bridge_fd 0
+ # example for setting manually the bridge address to the eth0 NIC
+ up ip link set addr $(cat /sys/class/net/eth0/address) dev $IFACE
