TLDR: Trying to Ubuntu 22.04 VM with 64 Gig Memory on ProxMox. Get Out of Memory Error. Won't even INSTALL.
Dear Team,
I have combed through all of the posts and I still can't seem to find out why my 128G Machine isn't able to allocate more than 32 Gigs of Ram for my Linux Server Host VM.
To help debug issue here are the stats of my current PROXMOX bare-metal machine:
Here is the smem utility
Anyw ideas?! I have combed through this entire list, and can't find an answer?!!
