This test area is concerned with Xen DomU functionality, which is based on the pv_ops work in upstream Linux. We need to make sure that Xen DomU is roughly as functional as the earlier, non-upstream versions of Xen DomU (i.e. RHEL-5, Fedora 8, etc.).
Prerequisites
You need a distribution with Xen Dom0 support. This can either be Red Hat Enterprise Linux 5, CentOS 5, Suse, Fedora 8, etc. We also highly recommend that your distribution is fully updated to the latest released packages.
If you are running a RHEL-5 Dom0, there are some 5.4 preview packages available here. These packages should allow you to do 32pv-on-64 dom0 testing, if you are so inclined. Note that these packages are not supported by Red Hat in any way, they are just for testing.
Note that in all of the test cases, unless otherwise stated, all commands should be run as root.
Tests
Follow each of these test cases:
- Guest install
- Memory ballooning
- Save/restore
- Live migration
- Guest pause/unpause
- CPU hotplug
- Network devices
- Block attach/detach
- Paravirt framebuffer
- Guest crash dump
- Execshield
- GDB
- Statically linked binaries
- Kernel command line parameters
- Host machine lacking NX support
If possible each of the tests should be repeated for:
- 32-bit DomU on a 32-bit Dom0
- 32-bit DomU on a 64-bit Dom0
- 64-bit DomU on a 64-bit Dom0
Results
If you have problems with any of the tests, file a bug report in bugzilla.
Once you have completed the tests, add your results to the table below.
User | Dom0 | Install | Ballooning | Save/restore | Migration | Pause | Comments |

Chris Lalancette | RHEL5.3 with virttestday pkgs | partially works http://bugzilla.redhat.com/499587 filed | partially works
x86_64:Hit http://bugzilla.redhat.com/499592, so only tested up to 2047MB |

Chris Lalancette | RHEL5.3 with virttestday pkgs | x86_64: Partially succeeded, can unplug CPUs, but not plug them back in. http://bugzilla.redhat.com/499611 | x86_64: Partially succeeded, can attach/detach disks, but trying to detach an in-use disk (eventually) causes guest crash. Large disks partially work, but can cause lockups. Attaching 70 disks works |
