Ever since xen-unstable cset 14308 ("pci back: Fix registration of of filters on subsections of config space") I''ve been getting an MCA on the *2nd* boot of a driver domain using an e1000 NIC. Cset 14308 allowed the proper setup of the PM control registers, so the NIC is put in the D3 power state when the driver domain shuts down. Unfortunately, pci_set_power_state()

Hi, I am a Masters student from Carnegie Mellon University. I am looking for a research topics for an Advanced OS & DS course we have. I wanted to know what is the current support for NUMA on Xen ? Does it support the IBM x440 and AMD64 Opteron ? Also, does the Xen scheduler do NUMA aware scheduling so it does not degrade the VM performace ? My group is currently looking into Scheduling
