Description

This test case verifies that block devices can be successfully attached to and detached from a Fedora Xen DomU.

How to test

Create a number of dummy files on your dom0 by running
```
$> for i in `seq 1 70` ; do dd if=/dev/zero of=/var/lib/xen/images/disk$i.dsk bs=1 count=1 seek=10G ; done
```
Note that this command will create sparse files, meaning that unless you write data to the disk, no actual disk space on your hard drive will be used.
If you have free VG space available in your LVM volumes on the dom0, create a few test LVs (for example, using: lvcreate -n test1 -L1G. If you have free space left in your partition table on the dom0, create 1 or more partitions to test with. If you don't know what this means, or you are worried about making modifications like this, just skip this step.

From the dom0, attach one of the files to the F-11 domU

$> virsh attach-disk f11 --driver file /var/lib/xen/images/disk1.dsk xvdb

Inside the guest, run
```
$> fdisk /dev/xvdb
```
You should be able to partition the disk however you want, create a new filesystem on it, etc.
From the dom0, disconnect the disk from the F-11 guest
```
$> virsh detach-disk f11 xvdb
```
FIXME: add test case for phy for LVM/partition
Download this script to the dom0, and make it executable with chmod +x Xen-domu-attach-disks.sh Note that your dom0 must explicitly have support for this, so if your dom0 does not, this test will not work.

The disks should be presented to the domU on attach-disk, and removed from the guest on detach-disk.
The F-11 guest should be able to use the disks like any other piece of storage.
