I'm trying to path through Nvidia GPU to do some machine leaning work but have no luck. VM is Ubuntu Server 20.04. It starts and RAM usage of the VM immediately goes to 100% and I can't login to it. It does not matter how much RAM I give to it. The interesting thing is that I can usually start this VM right after rebooting physical server, but even in this case it goes bad after couple of hours. Below are parameters this VM:
agent: 1
args: -cpu 'host,+kvm_pv_unhalt,+kvm_pv_eoi,hv_vendor_id=proxmox,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv_reset,hv_vpindex,hv_runtime,hv_relaxed,hv_synic,hv_stimer,hv_tlbflush,hv_ipi,kvm=off'
