Hi,
I just want to enable 64 bit bars for KVM usage, seabios 1.7.0 is
used in current qemu-kvm, which not handle 64 bit bars yet. I cloned
seabios code from kernel.org(seems no 64 bit bars supporting), but I
was not taking notice of the tree on http://git.qemu.org/, yes it has
already done

Hi,

Hello all,
I would like to introduce my new project and see if there are people
on this list who would like to meet up at KVM Summit this week and
give me some feedback.
I have a new project called Snabb Switch and it's an open source
ethernet switch for hypervisors. I'm aiming for a specific
Do not drop large spte until it can be insteaded by small pages so that
the guest can happliy read memory through it
The idea is from Avi:
| As I mentioned before, write-protecting a large spte is a good idea,

| jitter.
Use min() to cleanup mapping_level

In order to detecting spte remapping, we can simply check whether the
spte has already been pointing to the pfn even if the spte is not the
last spte for middle spte is pointing to the kernel pfn which can not
be mapped to userspace
Also, update slot and stat.lpages iff the spte is not remapped
It is more cleaner if we can update pte_access fist then set spte according
to pte_access, also introduce gfn_need_write_protect to check whether the
gfn need to be write-protected

Then, no mmu specified code exists in the common function and drop two
parameters in set_spte

Hi,
we have been using PCI passthrough with the Mellanox IB interface
(MT27500 Family [ConnectX-3]) on Debian 6.0.6, kernel 3.2.23 and
qemu-kvm-1.0 (both from backports). It worked fine until latest
update in backports to qemu-kvm-1.1.2. With newer versions IB device
probe in guest fails leaving
