Cool! It's very good since it tends to break.

There is no need to test qcow2/raw here since it shouldn't matter.
You can test qcow2 only, it is enough.

You're basing the assumption that the VM was raised with -net tap or
-net user with the right vlan.
Actually it would be nice to hot add the host back end too (available on
newer kvm's). It's not a must.

Doesn't it need to fail after the hot delete?

Thank you for your contribution Yolkfull, pci hotplug is an important
feature that we should test and stress.

Nice catch here, as dir would work on both command.com and *sh.

The snippet above can be turned on a utility function, I am going to
cook up a patch doing it. When finished, I will replace it myself, no
need to worry about it.

Above we could use a better schema to do line break, I'd rather see the
following:
raise error.TestFail("Not found pci model: %s; Command is: %s" %
(tested_model, cmd))
Implicit line continuation (using expressions in parenthesis) looks a lot better.

Ditto for line continuation.
We have just removed a device, why would we expect it to function after
the removal?

The above exception might be slightly misleading, as the VM is not
damaged, just something went wrong during the whole PCI addition
process. My suggestion is something along the lines:
"Check for %s device failed after PCI hotplug" % test_type

Yes I think. Sometimes the pci_del will succeed whereas it may break the

Hi Glauber, according to Dor's comments on this, I did some testing and
got an interesting result for block_hotplug:
1) hotplug storage of raw + SCSI will always fail on Windows
2) hotplug storage of Raw + Virtio will always fail on Fedora
3) hotplug storage with image format Raw will also fail often on RHEL
Does block_hotplug relate to image format? Would you give me any clue
on this?
Thanks in advance.

It shouldn't matter. In case the test is sensitive for timeout, it might.
Can you describe what's working and what's not on each combination?
As for scsi, it is not reliable so it might be scsi's fault.
Can you provide the fdisk -l ouput on Fedora when it is not working?
From the test below, there is not time/event for letting the guest hook
up the new block device.
Maybe you need to do several retries in a loop or check a real event in
the guest (better one)

Hi,
hotplugging a pci device should have nothing to do with the underlying format.
However, if we are using a format that is more racy and subject to breaks, the
hotplug window may make easy for race conditions to happen. For example, qcow2
with writeback caching.
As for the failures you describe, I'd like to see details. They surely sound like
a bug.

I can make sure now there is a bug in block hotplug feature since segfault has been found in
dmesg on my laptop Fedora. Also, both guest RHEL.5.3-i386 and Windows 2008 have
crashed during running block_hotplug test.
For example, for Windows 2008-32 guest, sometimes issue command 'systeminfo' during block_hotplug
can crash the guest.
I had added a loop wait for the PCI device hooked up, before this, I
used sleep(some_seconds) wait for module installed.

Differences between previous patch:
- Use a loop waiting for some seconds to compare output of a command
- Use a loop waiting for some seconds to catch string indicates which
PCI device
- Add option kill_vm_on_error in block_hotplug since once a model failed
to be hot removed, it will affect next model
A better result I can get is:
