Hello all,
I am attempting to set up Proxmox with PCI passthrough for GPUs.
The actual passthrough works perfectly, but only with low RAM values.
As soon as I allocate more than about 24G of ram to a VM, the VM will refuse to start.
Pressing the start button results in in either a perpetual spinning circle or a time-out error.
Without the GPU passed through, any RAM amount works fine.
Has anyone encountered a similar issue?
