[Xen-users] Adding a block device to a new Linux Guest

["Omer Khalid" <Omer.Khalid@xxxxxxx>]

Hi,

I am trying to add an additional block device (read-only) to my guest VM where I want to put some additional software necessary for my executing code in the VM. I am following the following steps:

1) add the additional disk entry to the xen configuration

    disk = ['phy:/dev/volumegroup/xen-root,xvda1,w','phy:/dev/volumegroup/xen-swap,xvda2,w', 'phy:/dev/volumegroup/software,xvdb1,r'  ]

2) In the guest OS image /etc/fstab file, I have added the following line to mount the additional block device when booted;

    /dev/xvdb1      /software               ext3            defaults                0       0

3) In guest OS root filesystem, i have created the "software" directory so that fstab could mount it to the additional block device at the boot time

4) Then I start the guest VM.

The problem is that the guest boots up and works fine but there is neither a block device /dev/xvdb1 available nor mounting it manually to /software works!

Any ideas? I have tried both "xvdb" and "xvdb1" in the xen configuration files but luck so far!

Thanks for your help in advance!
