The virtiofs project started off using "virtio-fs" but later switched to
the "virtiofs" spelling because it matches the spelling of the mount -t
virtiofs command-line. Update the kbase article with the new spelling so
it matches the virtiofs website.

The virtiofs kbase article includes a lot of information that is only relevant
to old versions of QEMU and libvirt. Setting up virtiofs can seem intimidating
but it's actually easier than the article lets on. Move the legacy information

Nowadays memfd is the most convenient memory backend for vhost-user
devices. Compared to file-backend memory and hugepages, there is no need
to worry about configuring the location of the shm directory or
allocating hugepages.

Hi,
libvirt refuses to set KVM_HINTS_DEDICATED when the CPU model is not
host-passthrough.
Is there a reason for this limitation?
My understanding is that KVM_HINTS_DEDICATED means the vCPU is pinned to
a host CPU that is not shared with other tasks. Any KVM vCPU should be
able to support this fe

What happens with the target dir?
virtio-fs has no way to pass the target dir into the guest.
Out-of-band methods exist: qemu-guest-agent could be used to mount the

Hi,
LWN.net is a popular open source news site that covers Linux and other
open source communities (Python, GNOME, Debian, etc). It has published
a few KVM articles in the past too.
Let's raise awareness of QEMU, KVM, and libvirt by submitting articles covering
KVM Forum.
I am looking for ~5 vol
Dear QEMU, KVM, and libvirt communities,
virtio-fs is a shared file system that lets virtual machines access a
directory tree on the host. Unlike existing approaches, it is designed
to offer local file system semantics and performance. The guest can
take advantage of Linux DAX to access file cont

Hi Michal,
You asked how NVDIMM hotplug should work if the domain was launched
without -M nvdimm=on. I'm not very familiar with ACPI so this may be
incorrect.
Hotplug relies on the presence of ACPI tables (SSDT Device=NVDR
_HID=ACPI0012) added by -M nvdimm=on. The ACPI tables contain the
