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
hv_utils -- Hyper-V Utilities Driver SYNOPSIS
To compile this driver into the kernel, place the following lines in the system kernel configuration file: device hyperv DESCRIPTION
The hv_utils driver provides time keeping, shutdown and heartbeat functionality for FreeBSD guest partitions running on Hyper-V. Hyper-V is a hypervisor-based virtualization technology from Microsoft. The hv_utils driver is one of the core drivers required to be present in guest partitions running on Hyper-V. This driver provides the following functionalities to guest partitions: (a) Time Keeping: The clock inside the guest partition will remain accurate by synchronizing to the clock on the virtualization server via Timesync service, and with the help of the pluggable time source device. (b) Integrated shutdown: Guest partitions running FreeBSD can be shut down from Hyper-V Manager console by using the "Shut down" command. (c) Heartbeat: This feature allows the virtualization server to detect whether the guest partition is running and responsive. SEE ALSO
hv_ata_pci_disengage(4), hv_netvsc(4), hv_storvsc(4), hv_vmbus(4) HISTORY
Support for hv_utils first appeared in FreeBSD 10.0. The driver was developed through a joint effort between Citrix Incorporated, Microsoft Corporation, and Network Appliance Incorporated. AUTHORS
FreeBSD support for hv_utils was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>. BSD
