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

PAM_GUEST(8)						    BSD System Manager's Manual 					      PAM_GUEST(8)

NAME
pam_guest -- Guest PAM module SYNOPSIS
[service-name] module-type control-flag pam_guest [arguments] DESCRIPTION
The guest service module for PAM allows guest logins. If successful, the pam_guest module sets the PAM environment variable GUEST to the login name. The application can check this variable using pam_getenv(3) to differentiate guest logins from normal logins. The following options may be passed to the pam_guest module: guests=list Comma-separated list of guest account names. The default is ``guest''. A typical value for ftpd(8) would be ``anonymous,ftp''. nopass Omits the password prompt if the target account is on the list of guest accounts. pass_as_ruser The password typed in by the user is exported as the PAM_RUSER item. This is useful for applications like ftpd(8) where guest users are encouraged to use their email address as password. pass_is_user Requires the guest user to type in the guest account name as password. SEE ALSO
pam_get_item(3), pam_getenv(3), pam.conf(5), pam(8) AUTHORS
The pam_guest module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program. BSD
