Hi all,
I have a KVM system running debian squeeze with the backports qemu-kvm packages:
# dpkg --list |grep kvm
ii qemu-kvm 1.1.2+dfsg-5~bpo60+1 Full virtualization on x86 hardware
I'm running 2 VM's with Windows 7 installed.
The software running on the VM's require a hardware USB dongle

So this won't work, unless we add the is_kernel_addr check
to might_fault. That will become possible on top of this patchset
but let's consider this carefully, and make this a separate

Yes, makes sense.

Summary: VM performance degradation after KVM QEMU migration or
save/restore with Intel EPT enabled
Product: Virtualization
Version: unspecified
Kernel Version: 3.0+
Platform: All
We currently send all mappings to the iommu in PAGE_SIZE chunks,
which prevents the iommu from enabling support for larger page sizes.
We still need to pin pages, which means we step through them in
PAGE_SIZE chunks, but we can batch up contiguous physical memory
chunks to allow the iommu the
We need to keep track of all the DMA mappings of an iommu container so
that it can be automatically unmapped when the user releases the file
descriptor. We currently do this using a simple list, where we merge
entries with contiguous iovas and virtual addresses. Using a tree for
this is a bit
This series let's the vfio type1 iommu backend take advantage of iommu
large page support. See patch 2/2 for the details. This has been
tested on both amd_iommu and intel_iommu, but only my AMD system has
large page support. I'd appreciate any testing and feedback on other
systems, particularly

If setting TscSequence to zero makes Windows fall back to the MSR this is a
better option.
+1
This is why MS has two different mechanisms:
iTSC as a primary, reference counters as a fall-back.

We can easily reach the 1000 limit by start VM with a couple
hundred I/O devices (multifunction=on). The hardcode limit

In userspace, we already have maximum file descriptor to
