Xen 4.15 RC test instructions
|If you come to this page before or after the Test Day is completed, your testing is still valuable, and you can use the information on this page to test, post any bugs and test reports to xen-devel@. If this page is more than two weeks old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.|

What needs to be tested
- Making sure that Xen 4.14 compiles and installs properly on different software configurations; particularly on distros
- Making sure that Xen 4.14, along with appropriately up-to-date kernels, work on different hardware.
For more ideas about what to test, please see Testing Xen.
ARM Smoke Testing
If you use ARM Hardware, which is not widely available or not rackable (and thus not part of our automated test suite), please check out Xen ARM Manual Smoke Test. Helping out to manually test ARM boards (which will only take a few minutes) will guarantee that Xen 4.14 will work on the board that you use. If you want to see which boards need testing, check Xen ARM Manual Smoke Test/Results.
- Use x2APIC mode whenever available, regardless of interrupt remapping support. - Performance improvements to guest assisted TLB flushes, either when using the Xen hypercall interface or the viridian one. - Assorted pvshim performance and scalability improvements plus some bug fixes. - Hypervisor framework to ease porting Xen to run on hypervisors. - Initial support to run on Hyper-V. - Initial hypervisor file system (hypfs) support. - libxl support for running qemu-xen device model in a linux stubdomain. - New 'domid_policy', allowing domain-ids to be randomly chosen. - Option to preserve domain-id across migrate or save+restore. - Support in kdd for initial KD protocol handshake for Win 7, 8 and 10 (64 bit).
Getting a RC
For the expressions/examples below, set the following bash/sh/... variable to the release candidate number (e.g. one of
rc2, ... )
RC="<release candidate number>" # rc1, rc2 ...
For RC1: RC=rc1 (see #RC1)
With a recent enough
git (>= 18.104.22.168), just pull from the proper tag (
4.14.0-$RC) from the main repo directly:
git clone -b 4.14.0-$RC git://xenbits.xen.org/xen.git
With an older
git version (and/or if that does not work, e.g., complaining with a message like this:
Remote branch 4.14.0-$RC not found in upstream origin, using HEAD instead), do the following:
git clone git://xenbits.xen.org/xen.git ; cd xen ; git checkout 4.14.0-$RC
- RC1 & RC2: build failure version of golang older than 1.11: add --disable-golang to configure line to work around (fixed in RC3).
- Remove any old versions of Xen toolstack and userspace binaries (including
- Remove any Xen-related udev files under /etc because Xen 4.14 doesn't use those anymore.
- Download and install the most recent Xen 4.14 RC, as described above. Make sure to check the
INSTALLfor changes in required development libraries and procedures. Some particular things to note:
Once you have Xen 4.14 RC installed check that you can install a guest etc and use it in the ways which you normally would, i.e. that your existing guest configurations, scripts etc still work.

Reporting Bugs (& Issues)
- Use Freenode IRC channel #xentest to discuss questions interactively
- Report any bugs / missing functionality / unexpected results.
- Please put [TestDay] into the subject line
- Also make sure you specify the RC number you are using
- Make sure to follow the guidelines on Reporting Bugs against Xen (please CC the relevant maintainers and the Release Manager - jgross at suse dot com).
We would love it if you could report successes by e-mailing
email@example.com, preferably including:
- Hardware: Please at least include the processor manufacturer (Intel/AMD). Other helpful information might include specific processor models, amount of memory, number of cores, and so on
- Software: If you're using a distro, the distro name and version would be the most helpful. Other helpful information might include the kernel that you're running, or other virtualization-related software you're using (e.g., libvirt, xen-tools, drbd, &c).
- Guest operating systems: If running a Linux version, please specify whether you ran it in PV or HVM mode.
- Functionality tested: High-level would include toolstacks, and major functionality (e.g., suspend/resume, migration, pass-through, stubdomains, &c)
The following template might be helpful: should you use
Xen 4.14.0-<Some RC> for testing, please make sure you state that information!
