There are conflicting reports about wether or not Red Hat 4.0 is vulnerable to the login-lockout described earlier. I have the impression that if you install the updates it will have been fixed. Approval of messages about this subject is now restricted to "here is a patch", and a vendors "We have made a patch available". Roger.

I still need to add testsuite coverage. Perhaps it might be easier if I create a new '--filter=log logfile=foo' filter that produces a log of which commands a client sent, then compare the log using a known client that uses write_zeroes (qemu-io works well) both with and without --filter=nozero to prove that the change in advertisement changes the commands sent over the wire (that would

This adds --print-target. In addition, v2 provides a machine-readable version (in JSON format). All of the record -> JSON boilerplate in this patch could be eliminated if we moved the baseline to OCaml 4.02. Rich.

Hi Rob & Mihai, I wrote vhost-nvme patches on top of Christoph's NVMe target. vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe driver. But the tests I have done didn't show competitive performance compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme vendor extension patches reduces greatly the number of MMIO writes. So I'd like to push it
