[one-users] one and xen block configuration

[Stefan Freitag]

Hi Javier,

I agree with you that tap:aio should be used instead of file:, but
sometimes it is not possible :-(
In Dortmund we had SLES 10 in place as OS for the physical machines and
this rejected to work properly with tap:aio.

SLES, as it is an enterprise server edition of SUSE, does not include the
latest/ bug-fixed versions of e.g. XEN and libvirt :-(

Cheers
Stefan
