Re: [Xen-users] CentOS 4.0 as guest OS

["rishi pathak" <mailmaverick666@xxxxxxxxx>]

Hi ,
The problem is that we have got a high speed interconnect and the driver for it was compiled for 2.6.9-5 EL.
We have got only binaries of the driver and not source.For this reason we have to stick to the said kernel.

Let me explain the scenario/problem for which we need virtualization.We
have a compute cluster with nodes having 8GB of memory.The nodes are
all dual socket single core Intel Xeon.The driver for high speed
interconnect can only work with 4GB of available RAM(i.e. it cannot see
more than 4GB).If I restrict RAM to 4GB then it would be a wastage.So
the solution that came up was to divide node into two virtual machine
and assign high speed interconnect to one virtual machine.Both machines
will have 4GB.

I don't know of a CentOS4.0/RHEL4.0 kernel patched to work with xen;
XenSource had some 4.4 kernels in the 3.0.2 days.  If you can upgrade to
CentOS 4.5, it comes with Xen DomU kernels out of box.
