Hi, this is the first patch for drivers domains. With this patch and another one for pcifront, I was able to use an ethernet card in a domU. This patch adds the IOPORT_PERMISSION hypercall (with no effects other than setting the rangeset), checks iomem caps and provides a more flexible way to handle memory attribute. Currently IO ports are not supported in driver domain. I'd plan to start a discussion about it. Tested by using a ethernet card in domU and retesting live migration. Tristan.
