Hi everyone,
i have a very simple question so sorry if it looks like an stupid one. If i want to support an specific hardware on a domainU, which of the kernels (domain0 or domainU) should have compiled in the support?
If you want a domU with hardware access you have to compile that into the domainU kernel. If you compile configs you will find that the dom0 kernel already has hardware support (like pci support e.g.) compiled in.
Of course I meant "If you COMPARE configs ..." (sorry for the nonsense).

Which
is the best way to change the default kernel .config used by xen at
compile time? (Using xen-unstable-src)


Get the .config from someone who already succeeded in what you try to do. :-)

Then use config=menuconfig to get a text based menu for configuration of the changes you have to make for YOUR hardware.

What exactly do you have in mind? Which hardware do you want to access from domU?

        An HBA fiber channel card to connect the domainU to a SAN.

Then you need at least PCI support and the module for the FC HBA.

Dirk
