What to test?[edit]
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.
Who's available[edit]
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:
What's needed to test[edit]
- A distribution with Xen Dom0 support. This can either be Red Hat Enterprise Linux 5, CentOS 5, Suse, Fedora, etc. We also highly recommend that your distribution is fully updated to the latest released packages. See instructions on the main test day page.
- At least one guest image installed before the test day (suggested reading - Virtualization_Quick_Start).
Known issues and workarounds[edit]
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. There are no known issues with a RHEL 5.5 host. Other host platforms and/or Xen packages may have varying results. Please test :-)
- RHEL specific: pygrub does not support ext4, however rawhide defaults to ext4. Therefore this must be manually changed to ext3 (at least for /boot) during the installation, or an appropriate kickstart can be used.
- RHEL specific on machines with GB pages: add 'nogbpages' to the guest kernel command-line for guests with >2GB memory, see bz502826
- RHEL specific on machines with xsave: add 'noxsave' to the guest kernel command-line for hvm guests, see bz524052
