Hi,
I am trying to use DPDK SRIOV passthrough with DPDK on Intel NICs.
I am following the instructions in "Network Interface Controller Drivers", in
http://fast.dpdk.org/doc/pdf-guides/nics-16.07.pdf
I saw in "11.2 Setting Up a KVM Virtual Machine Monitor" in this pdf
that it says to
download qemu-kvm-0.14.0 from
http://sourceforge.net/projects/kvm/files/qemu-kvm/
,build it and run /usr/local/kvm/bin/qemu-system-x86_64
My question is:
there is also qemu-system-x86_64 executable in qemu Fedora rpms.
It is built from the qemu project which is hosted on http://www.qemu.org.
I made a brief comparison between the trees of both these projects
(qemu and KVM qemu-kvm) and
they seem different.
Should SRIOV passthrough, as described in the aforementioned DPDK
nics-16.07.pdf, work also with this qemu-system-x86_64 from the qemu
project?
or is using the qemu-system-x86_64 of the qemu project is not good
enough, and using
KVM qemu-system-x86_64 from
http://sourceforge.net/projects/kvm/files/qemu-kvm/ is a must ?

Kevin

I have used qemu-system-x86_64, (directly downloaded and compiled from http://www.qemu.org) without any issue, be sure that kvm is enabled by setting "accel=kvm" in the qemu command line.

Thanks!

Isn't "--enable-kvm" intended for that ?
Sorry, I meant "-machine accel=kvm".
I don't know what is the exact difference but enable-kvm should also work.
