I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

On 32e, we create one guest, then hotplug attach one NIC to guest, guest can not get IP address via dhcp, guest qemu log shows "libpci read error. No emulation ". Here is the bug entry: One 32e, hotplug attaching VT-d NIC to guest failed. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1316. -- haicheng _______________________________________________ Xen-devel mailing list

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the

The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

This patch adds the function that reassign page-aligned memory resources, to dom0 linux. The function is useful when we assign I/O device to HVM domain using pci passthrough. When we assign a device to HVM domain using pci passthrough, the device needs to be assigned page-aligned memory resources. If the memory resource is not page-aligned, following error occurs. Error: pci: 0000:00:1d.7:

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

Hi all, I downloaded the xen 3.3.0 and now testing the pci pass-through with the NIC. Using late binding, the pci slot 0000:08:01.0 is assigned to pciback. But pci related xm commands are not working. For eg: linux-242:/home/xen-3.3.0 # xm pci-list-assignable-devices Unexpected error: <type ''exceptions.OSError''> Please report to

Currently, Xen does not support injecting an NMI to HVM guest OS. Adding this feature is necessary for those softwares which depend on NMI to function correctly, such as KDB and oprofile. The attached patch allows NMI to be injected to guest OS in NMIP capable platforms. It also enables to queue an NMI and then inject it as soon as possible. Signed-off-by: Haitao Shan

This patch fixes compilation error when CONFIG_PCI_REASSIGN is not set. The patch depends on following patches I have sent.

This patch fixes libpci error handling. It can be applied to both ioemu-remote and ioemu. libpci returns ALL F when error occurs. Currently, if libpci returns ALL F, emulation stops. But it is possible that the field of real register which is read by guest software is ALL F. After applying this patch, if libpci returns ALL F, ioemu will log warning message and continue the emulation.

This patch enables PCI passthrough with stub domain. PCI passthrough with stub domain has failed in the past. The primary reason is that hypercalls from qemu in stub domain are rejected. This patch allows qemu in stub domain to call the hypercalls which is needed for PCI passthrough. For security, if target domain of hypercall is different from that of stub domain, it rejects hypercall. To use

I have successfully passed through a video card, network card, USB mouse, and USB keyboard to a MS Vista guest. That works well. I am trying to add another PCI device, such as a audio card or PCI USB hub, but I am running into a strange problem. When I plug the PCI audio (or USB card) to the motherboard. It makes it so that the PCI video card is no longer an "assignable device" (xm

I have pulled a recent (today''s) clone of staging/xen-unstable.hg and I get a failure when trying to create a domain with xend/xm.
