- Add bhyve NVMe device emulation.
The initial work on bhyve NVMe device emulation was done by the GSoC student Shunsuke Mie and was heavily modified in performan, functionality and guest support by Leon Dang. bhyve: -s <n>,nvme,devpath,maxq=#,qsz=#,ioslots=#,sectsz=#,ser=A-Z accepted devpath: /dev/blockdev /path/to/image ram=size_in_MiB Tested with guest OS: FreeBSD Head, Linux Fedora fc27, Ubuntu 18.04, OpenSuse 15.0, Windows Server 2016 Datacenter. Tested with all accepted device paths: Real nvme, zdev and also with ram. Tested on: AMD Ryzen Threadripper 1950X 16-Core Processor and Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz.
