Thanks, Mihal. That worked perfectly! To answer your first question, the guest is used to test various software, including an installation ISO. Part of the installer uses dmidecode -t17 to detect the amount of RAM and indicate to the user if they have enough memory to complete the install. This works fine with real hardware, but the VM didn't report any of that, hence my problem.

First, my details: Host machine: rlott@rlott-brix:~$ uname -a; lsb_release -a Linux rlott-brix 4.13.0-46-generic #51-Ubuntu SMP Tue Jun 12 12:36:29 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 17.10 Release: 17.10 Codename: artful VirtualBox version: 5.2.6 r120293 (Qt5.9.1) Guest VM: Custom Ubuntu version root@magtestvm:/udata/home/etdev# uname -a; lsb_release Linux magtestvm 4.4.0-116-generic #140~14.04.1-Ubuntu SMP Fri Feb 16 09:25:20 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux I was wondering if there was a way to populate the DMI information to simulate memory banks for a Linux-based VM. If I do a dmidecode -t17 on my guest, I see the following: root@magtestvm:/udata/home/etdev# dmidecode -t17 # dmidecode 2.12 SMBIOS 2.5 present. Upon further examination, I saw in the full dmidecode output that no such memory bank sections existed. I found this section in the manual about setting DMI information: https://www.virtualbox.org/manual/ch08.html#idm5744 I saw in this piece of the source code that it does support DMI Memory (type 17): https://www.virtualbox.org/svn/vbox/trunk/src/VBox/Devices/PC/DevFwCommon.cpp So, is there such a call to set various things like this? VBoxManage setextradata <my_guest_vm> VBoxInternal/Devices/pcbios/0/Config/DmiMemory/<some_key> <some_value> If so, would you point me to where a list of values for <some_key> would be? Thanks very much!
