Personally, I think that a vm could take all cpu usage, or memory, and impact ceph cluster for other vms.
we should give ceph some kind of (configurable) priority. ----- Mail original ----- De: "dietmar" <diet...@proxmox.com> À: "pve-devel" <pve-devel@pve.proxmox.com>, "aderumier" <aderum...@odiso.com> Envoyé: Lundi 23 Juillet 2018 20:53:19 Objet: Re: [pve-devel] Hyperconverged Cloud / Qemu + Ceph on same node I am not sure CPU pinning helps.
