[proxmox.com,daktela.com,vadesecure.com] Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Content-Filtered-By: Mailman/MimeDel 2.1.29 Hi, Looking at the code, it's 1024MB * the number of sockets, so adding sockets might be workaround. Thanks for the idea. Another workaround might be to simply disable memory hotplug before leapp. The kernel option "memhp_default_state=3Donline" also works. However, I thi= nk the ability to configure the startup RAM size in Proxmox would be nice.
