Subject: [PATCH manager 1/1] ui: processor edit: allow setting 8 sockets
Date: Mon,  6 Jul 2026 13:47:11 +0200	[thread overview]
Message-ID: <20260706114719.340123-1-m.sandoval@proxmox.com> (raw)

As per our NUMA documentation [1]:

> If the NUMA option is used, it is recommended to set the number of sockets to
> the number of nodes of the host system.

Nowadays, it is common to find CPU models with 8 NUMA nodes. Two examples are
Xeon Platinum 8160 and EPYC 73F3.

The schema at qemu-server does not limit the socket amount. However, $MAX_NUMA
is hard-coded to 8 at qemu-server's Memory.pm , so we bump it to 8 to be on the
safe side.
