Subject: [PATCH] make vfio and DAX cache work together
Date: Sun, 25 Apr 2021 22:45:12 -0700	[thread overview]
Message-ID: <20210426054513.132980-1-edgenfv@gmail.com> (raw)


I am using Kata containers and create containers inside the virtual machine. The hypervisor used is QEMU.
My workload is I/O and network intensive. So, I prefer SR-IOV VF (which provides better network isolation) and DAX caching to work together.
However, I was unable to create a QEMU based virual machine when the above mentioned featires are enabled together.

Currently DAX cache need to be set to 0, to boot the VM successfully with the SR-IOV VF to be attached.
Enabling both SR-IOV VF and DAX work together will potentially improve performance for workloads which are I/O and network intensive.
This patch enables SR-IOV VF and DAX to work together.
