That's why I have sent you the patch for guest virtio-net driver. I reserved
512 bytes in each page, then I can always have the space to copy and avoid the

OK, this new way can work when create guest with static assignment.
But how to hot add a pci device to guest? the old hot add command "pci_add
pci_addr=auto host host=00:19.0" has the same parse error.
BTW: if we use add "-net none" in qemu command, g
Apparently, not all page faults on the guest result in a page fault in the
host. I would like to intercept page faults on the guest that are not handled
by the host.
I am not quite sure where (in the source code) can I monitor that?
Can any one give me code pointers to look at?

If we have a certain file that has information about
running unit tests, let's build the unittests on the
build.git mode. This feature depends on a qemu-kvm patch
that is still not upstream, but I am sending anyways so
people can comment.

For unittesting, for example, is interesting that we
run the VM with the bare mininum number of parameters.
This fix allows that.

KVM autotest, add rules to install the flat files to

Also, add a unittests.cfg file, a simple .ini file

This patch adds support for dynamically enabling/disabling of trace events.

permitting logging of data from a trace event only if it is in an
