Hi, libvirt-users How could I set up a memory-only and no-cpu NUMA node for the qemu-VM with the XML file? Seems each NUMA cell has to be bundled with some specific cpuids. If I write the element like this, it is wrong. <cpu mode='host-passthrough'> <numa> <cell id='0' cpus='0-3' memory='16' unit='GiB'/> <cell id='1' cpus='*null*' memory='16' unit='GiB'/> </numa> </cpu> Also if I ignore the cpus item, it is not acceptable for the virsh command. The reason I want the memory-only node is that I want to set up multiple memory tiers for the VM, just like https://stevescargall.com/2022/06/10/using-linux-kernel-memory-tiering/ Thank You Best Jin Huang

What you want to configure is so called HMAT (Heterogeneous Memory Attribute Table). It can be configured by leaving out the @cpus attribute completely. For instance like this: <cpu mode='host-model' check='partial'> <numa> <cell id='0' cpus='0-5' memory='512000' unit='KiB' discard='yes'> <distances> <sibling id='0' value='10'/> <sibling id='1' value='21'/> </distances> <cache level='3' associativity='direct' policy='writeback'> <size value='10' unit='KiB'/> <line value='8' unit='B'/> </cache> <cache level='1' associativity='direct' policy='writeback'> <size value='8' unit='KiB'/> <line value='5' unit='B'/> </cache> </cell> <cell id='1' memory='512000' unit='KiB'> <distances> <sibling id='0' value='21'/> <sibling id='1' value='10'/> </distances> </cell> <interconnects> <latency initiator='0' target='0' cache='1' type='access' value='5'/> <bandwidth initiator='0' target='0' type='access' value='204800' unit='KiB'/> </interconnects> </numa> </cpu> This was introduced in libvirt-6.6.0 so you may need to upgrade.

Hi, Michal Thank you for your help. After compiled and installed libvirt-6.7.0, when I try virsh define xmlfile, it says "error: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm". The way I compiled and installed libvirt-6.7.0 is according to https://libvirt.org/compiling.html My system is Ubuntu20, originally I used apt to install the libvirt, it works well, just not support HMAT. Do you know how to fix my current issue? Thank You Best Jin Huang On Fri, Aug 5, 2022 at 5:34 AM Michal Prívozník <mprivozn@redhat.com> wrote:

This is pretty much expected if you had libvirt installed from your package manager (which I believe is the case because of the network error). I don't know what the correct way to build a .deb package is, but on rpm based distros I usually build a .tar.xz (meson dist) from which I build a .rpm (rpmbuild -ta) and then install it. Michal

The easiest way is to use a package from a newer Ubuntu version. I'd suggest using the oldest good enough version available to avoid problems with dependencies. You may still be forced to use a newer libc or so. In such a case, you can either configure your system (in /etc/apt/) to use some packages from a newer Ubuntu version, or to rebuild the newer libvirt package using instructions from https://wiki.debian.org/BuildingTutorial#The_packaging_workflow
but on rpm based distros I usually build a .tar.xz (meson dist) from which I build a .rpm (rpmbuild -ta) and then install it.

You could grab the source package for the latest version of libvirt available in Debian, which would be https://deb.debian.org/debian/pool/main/libv/libvirt/libvirt_8.5.0-1.dsc right now, and then follow the instructions in https://wiki.debian.org/BuildingTutorial#Get_the_source_package to rebuild it locally targeting your release of Ubuntu.

As I said in the previous message, I'd rebuild the Debian package instead of building from source. That way, you should be able to seamlessly replace the version of libvirt that you had installed from Ubuntu 20.04's repositories with a newer one.

Hi, Andrea After installing the debian-keyring package, no that issue. Thank you so much.
But I tried this under libvirt-8.5.0/ dpkg-buildpackage --no-sign
dpkg-checkbuilddeps: error: Unmet build dependencies: debhelper-compat (= 13) libc6-dev (>= 2.31-14~) meson (>= 0.54.0~) qemu-system-common:native
But my meson version is 0.63.0, which should satisfy this dependency requirement;
You have probably installed that version using pip or some other method, so dpkg doesn't know about it and can't use it to satisfy the Build-Depends. Anyway, it looks like Ubuntu 20.04 is much farther behind Debian sid than I thought was the case. You could probably hammer the package into a shape that can be built on that platform with enough effort, but I'm not convinced it would be worth it. Please consider moving to Ubuntu 22.04, the current LTS release. The steps I provided will work there. -- Andrea Bolognani / Red Hat / Virtualization
