[Xen-users] Paravirt VM - Second Disk not working

["Robert Dunkley" <Robert@xxxxxxxxx>]

Hi All,

I have a paravirt VM with two hard disks, the boot drive xvda works fine
but the data drive xvdb does not seem to detect at all. I have looked
into this and full logs are below but I cannot find what is causing the
timeout on connect. Feedback from Dom0 for both devices looks identical,
the only error I get is the timeout in DomU. Does anyone know what might
be causing this?

Thanks,

Rob
