Hi,
The following two patches add event mask support in kvmtrace and the
corresponding kernel code, so that we can specify filter masks to limit
the events being captured.

Thats a possibility, but I think we've now agreed that doing select() with

This patch introduces virtio support over PCI. virtio is a generic virtual IO
framework for Linux first introduced in 2.6.23. Since 2.6.25, virtio has
supported a PCI transport which this patch implements.
Since the last time these patches were posted to qemu-devel, I've reworked it
to use the
This patch implements the virtio network driver backend. In KVM, this driver
can achieve 1gbit tx/rx performance. More patches are required to improve the
network IO infrastructure to achieve better performance in QEMU.
Since v1, I've updated the patch based on the IOVector refactoring.
This patch implements the virtio block driver backend.
