Nowadays I am troubling with Xenoprofile!I want to use Xenoprofile to get the exact cost of xen block-device backend/frontend driver ,so I can find the bottleneck and improve on it.But with the manual of xenoprofile, driver is in the layer operating system.If we wanna to test the driver cost, we must compile the driver in modules but not in the kernel.After I compile the driver in modules, I can't make the domainU started and it said that can't find block device because when domainU is being started, there is no driver to read the block device.
How can I solve this problem?
