Hi, I''ve been trying to boot stefano''s minimal dom0 kernel from git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git 2.6.36-rc1-initial-domain-v2+pat On xen-unstable, I get the following WARN_ON()''s from Xen when bringing up the NIC''s, then the machine hangs forever when trying to login either over serial or NIC. (XEN) Xen WARN at msi.c:649 (XEN) ----[

PCIe endpoint framework provides APIs to implement PCIe endpoint function. This framework allows defining various PCIe endpoint function behaviors in software. This patch extend the framework for virtio pci device. The virtio is defined to communicate guest on virtual machine and host side. Advantage of the virtio is the efficiency of data transfer and the conciseness of implementation device
