KVM/Qemu allocated memory not showing in guest

So we have a RHEL 7.6 workstation with 128 gigs of ram. The OS sees all the ram and 80 cors (40 HT)


We have 1 guest with 8 CPUs and 32gigs of ram running RHEL 7.6 workstation as well. We are trying to create another guest with 64 CPUs and 80 gigs of ram. We setup the system using virt-manager and PXE boot the system to install the OS.


All this goes without a hitch, but when we log in after the system is build with PXE and do a free -g it only shows 2 gigs instead of 80 gigs.


I have tried many variation of memory including 64gigs, but each time we try something above 32gigs, its only shows 2gigs.


Any ideas?
Thanks!

Joe

NAME
bootcdflopcp - copy changes made after booting from bootcd to floppy SYNOPSIS
bootcdflopcp [-v] [-d <device>] DESCRIPTION
bootcdflopcp will copy changes made in ram to the floppy disk. bootcdflopcp will be available as soon as your system is running from cd. The floppy has to have a filesystem already. (See mke2fs or mformat). If you have to boot from floppy, because your cd-drive or bios does not support to boot from cd a msdos filesystem is used to run syslinux. When bootcdflopcp is called it searches for differences between RAM and CD. For each different file, it checks if it is listed in the files ignore, remove or change on floppy. If it is listed in change it will be saved to change.tgz on floppy. If it is listed in remove the file will be removed from ram next boot time. If it is listed in ignore it will be ignored. If it is not listed at all you will be interactively asked what to do. OPTIONS
-v The option "-v" (verbose) adds messages on running. -d <device> Use another device instead of "/dev/fd0" to save changes. FILES
FLOPPY:/remove If a file is listed here the file will be deleted from ram next boot time. FLOPPY:/change If a file is listed here bootcdflopcp will save it in change.tgz. FLOPPY:/ignore If a file is listed here bootcdflopcp will ignore changes to this file. FLOPPY:/change.tgz Here all changed files are stored in gzipped tar format. SEE ALSO
