pci-passthrough nic but no link
I hope someone can enlighten me.
I have a quad-port Intel 82580 nic (igb driver) on my system and I''d like to
dedicate each nic to a HVM via VT-d PCI passthrough. The IOMMU on my system
seems to work, I can assign the PCI devices to my HVMs. The HVMs see the
pci device and load their respective igb drivers, and ethtool -i eth0 works
on each HVM, shows the drivers are loaded and the

RE: PCI passthrough on PV domU crashes with iommu=soft (fixed)
Fixed : Double amount of memory from 128 to 256 and iommu works it out fine.
RTFEM (read the fucking error message) :
[ 0.872160] Kernel panic - not syncing: Out of memory and no killable processes...

No IOMMU found. Unable to assign device
Hi,
I am playing around with PCI passthrough and came across some posts that
said you could not do PCI passthrough unless you had IOMMU hardware.
which it would appear I don't
Is this the case? Am I flogging a dead horse?
Thanks,
Marco

[PATCH v3] IOMMU: keep disabled until iommu_setup() is called
The iommu is enabled by default when xen is booting and later disabled
in iommu_setup() when no iommu is present.
But under some circumstances iommu code can be called before
iommu_setup() is processed. If there is no iommu available xen crashes.
This can happen for example when panic(...) is called as introduced
with the patch "x86-64: detect processors subject to AMD erratum #121

Re: Re: Unable to pass device to IOMMU
Sorry to duplicate my issues onto the list - I thought I had looked
through this thread before and seen a different error, but apparently
Adam and I are running into much the same thing. I'm seeing exactly the
same "Failed to assign device to IOMMU" along with the "Device not owned
by PCI Back End or pci-stub" in these scenarios. I have not gone back
to previous versions,

[PATCH, RFC] x86/iommu: don''t map RAM holes above 4G
Matching the comment in iommu_set_dom0_mapping(), map only actual RAM
from the address range starting at 4G. It''s not clear though whether
that comment is actually correct (which is why I''m sending this as
RFC), but it is certain that on systems with sparse physical memory
map we''re currently wasting a potentially significant amount of memory
for setting up IOMMU page

problems with xen and sr-iov/iommu
Hi all,
I''ve fetched the xen 4.0.1 source from the usual spot and have git''d the

capable x86_64 system, over a fedora 14 installation. Most of the

If its that way on PPC, than fine for them. But since this is enablement
for x86, it should follow the x86 platform best practices,

Vt-d not working with 3.4.1
Hi folks,
currently I try to setup a new xen host v3.4.1 on top of a Asus P5E-VM
DO (latest BIOS, Vt-d capable and enabled in BIOS) to migrate my
extisting HVMs (Win2k3 server) running on Xen v3.3.0 to a new home. I
want to switch over to 3.4.1 to (hopefully!) passthrough my ISDN board
to a HVM domU.
Unfortunate there seem some issue with the VT-d DMAR tables which is

A problem about xen no-iommu graphics card passthough
Hi!
I want to make windows work with native graphics card on xen with no iommu (no vt-d) support. With many googling, I find that xen with Neocleuse 1:1 No-IOMMU passthough patches maybe can meet my requestment.
I download and compile a copy of direct-io.hg source, and pass my graphics card to hvm
