Well, indeed, the message is pretty clear. maybe just add documentation about limit for q35 && i440fx ? (I have a customer with a new epyc v4, asking me about this, and I had no idea that they was a different limit between q35 && i440fx) with i440fx (and 512 cores) # qm start 105 kvm: Invalid SMP CPUs 512. The max CPUs supported by machine 'pc- i440fx-8.1' is 255 with q35 (and 4096 cores) # qm start 105 kvm: Invalid SMP CPUs 4096. The max CPUs supported by machine 'pc-q35- 8.1' is 1024 -------- Message initial -------- De: Fiona Ebner <f.eb...@proxmox.com> À: Proxmox VE development discussion <pve-devel@lists.proxmox.com>, "DERUMIER, Alexandre" <alexandre.derum...@groupe-cyllene.com>, d.csa...@proxmox.com <d.csa...@proxmox.com>, aderum...@odiso.com <aderum...@odiso.com> Objet: Re: [pve-devel] [PATCH pve-manager] qemu: bump max cores to 256 by socket Date: 15/01/2024 14:08:39 Am 15.01.24 um 13:43 schrieb DERUMIER, Alexandre: > > > Maybe an improvement in qemu-server, could be to add additional check > at vm start, (maybe a simple warn), depending of qemu version or > setup. > For example, 1024 cores only works with q35 && qemu 8.1, > it could be interesting to give an clean hint mesage to user instead > a qemu process error. > Is the QEMU error message understandable? If yes, I don't see much value in adding such a heuristic and warning ourselves. If no, we can either improve the QEMU error message or do as you suggested. _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
