Hi! We have a problem that the dom0 very often does not boot and hangs in the hypervisor - see screenshot. The last message is: (XEN) Dom0 has maximum 16 VCPUs (afterwards xen should overwrite the memory) We are using the xen kernel from kernel.org git. Kernel is 2.6.32.24-xen with Xen 4.0.1 Hardware is HP DL380. Is this a known problem? Any hints what could be the problem and how we can

Hello! I'm having problems getting PCI pass-through to work. This is on a AMD64 system, paravirtualized with xen-hypervisor-4.0-amd64 4.0.0-1~experimental.1, dom0: linux-image-2.6.32-5-xen-amd64 2.6.32-12. From IRC, earlier today: <tschwinge> waldi: Aren't the Debian xen domU-capable kernels supposed to contain the PCI frontend (needed for PCI pass-through)? I'm getting:

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine
