From what I have read, they are an performance impact with more than 64 dimm, and until they have fixed it, they don't want to increase value https://patchwork.kernel.org/patch/5825741/ "I'm almost done with approach suggested by Paolo, i.e. replace linear search with faster/scalable lookup alg. Hope to post it soon. " We can simply add a file: /etc/modprobe.d/vhost.conf options vhost max_mem_regions=509 But, as Wolfgang, I also think that be able to define optional fixed dimm size could be great too. ----- Mail original ----- De: "dietmar" <diet...@proxmox.com> À: "Wolfgang Bumiller" <w.bumil...@proxmox.com> Cc: "aderumier" <aderum...@odiso.com>, "pve-devel" <pve-devel@pve.proxmox.com> Envoyé: Mardi 13 Décembre 2016 16:37:41 Objet: Re: [pve-devel] qemu memory hotplug limited to 64 dimm > > Any drawbacks? > > It's a hack...
