Re: [Xen-devel] PCI passthrough for domU allocated with more than 4G memory
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Same problem here. I''m using gentoo with kernel 3.5.3 (gentoo-sources) and XEN 4.1.2 as dom0. DomU is also gentoo with the same kernel version. When I assign more than 4G memory to this domU, the memory for the passed-through Intel-gigabit-nic cannot be allocated and the initialization of the device fails. With 3968M memory assigned everything works fine. Assigning 8GB RAM to domU works without any problems, when I use the old kernel-version 2.6.34 (xen-sources) in domU.
