[edit] What to test?

This part of today's Fedora Test Day will focus on testing the area concerned with Xen DomU functionality, which is based on the pv_ops work in upstream Linux.

If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test Fedora as a Xen DomU and provide feedback.

[edit] Who's available

Andrew Jones (Drew) is your host for today.

The following people have also agreed to be available for testing, workarounds, bug fixes, and general discussion:

[edit] What's needed to test

[edit] Known issues and workarounds

Console may not work ('xm console <domain>') until 'console=hvc0' has been added to the kernel command line in grub.conf.

Note, the following list of issues were compiled while testing on RHEL 5.4. Other host platforms and/or Xen packages may have varying results. Please test :-)

If the above workarounds are done, or RHEL 5.5 is used, then these known issues will still be present.

* A fast way to create a working PV guest is to "convert" an FV guest that has an updated kernel and plymouth. To convert, just 1) recreate the initrd with xenblk included (e.g. mkinitrd --with=xenblk <initrd.img> 2.6.33.2-38.fc13), 2) change console=ttyS0,115200n8 to console=hvc0, 3) create a Xen PV config file to use. Copy the image file so you can run both the PV and the FV guests at the same time.
