this command is only used for debugging.

OK, I'll do some tests to select a right approach.
We should flush all tlbs after drop spte on sync_page path since:

We just need flush tlb if overwrite a writable spte with a read-only one.
And we should move this operation to set_spte() for sync_page path

I need to limit the port speed of a VM to 10 mbps ( or 5 mbps if it's possible).
What's the way of doing so?

When a devices is driven by userspace (like in the cases of KVM's

This interface doesn't make much sense, adding a capability can
take care of everything, just provide a means to register
capability read/write handlers.
Device assignment does it's own thing, so requires a couple
ugly hacks that will be cleaned by subsequent patches.

Capabilities are allocated in bytes, so we can track both whether
a byte is used and by what capability in the same structure.
Remove pci_reserve_capability() as there are no users, remove
pci_access_cap_config() since it's now a trivial lookup.

Capabilities aren't required to be contiguous, so cap.length never
really made much sense. Likewise, cap.start is mostly meaningless
too. Both of these are better served by the capability map. We
can also get rid of cap.supported, since it's really now unused
and redundant with flag in the
Now that common PCI code doesn't have a hangup on capabilities
being contiguous, move assigned device capabilities to match
their offset on physical hardware. This helps for drivers that
assume a capability configuration and don't bother searching.
We can also remove several calls to

Some drivers depend on finding capabilities like power management,
PCI express/X, vital product data, or vendor specific fields. Now
that we have better capability support, we can pass more of these
tables through to the guest. Note that VPD and VNDR are direct pass
through capabilies, the rest

Hello,
you may also have a look at VDE (Virtual Distributed Ethernet). You can
connect your VMs to virtual switches and then use the tool
'wirefilter'[1] to modify different attributes (bandwidth, loss, delay,
etc) of the virtual network.
