vsock notes

about vsocks

Vsocks are a means of providing socket communication (either stream or datagram) directly between VMs and their host operating system. The host and each VM have a 32 bit CID (Context IDentifier) and may connect or bind to a 32 bit port number. Ports < 1024 are privileged ports.

Vsock communication between VMs does not seem to work.
Only one vsock device per VM is supported.

Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.

Install QEMU

Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)

Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out the CPUs the AArch64 emulator can emulate):

qemu-system-aarch64 -M virt -cpu help

VFIO

Not KVM bound. The VFIO API deconstructs a device into regions, irqs, etc. The userspace application (QEMU, cloud-hypervisor, etc..) is responsible for reconstructing it into a device for e.g. a guest VM to consume.

Boot with intel_iommu=on.

IOMMU groups

Devices are bound together for isolation, IOMMU capabilities and platform topology reasons. It is not configurable.

Proxmox GPU Passthrough

Config :

Motherboard : ASUS PRIME B450M-A
CPU : AMD Ryzen 7 2700x
GPU : EVGA AMD RADEON R9 380 Series
Ram : DDR4 2133 MHz

Setting it all up

Update packages

Resize a VM system disk

Introduction

You have a VM with small disk
You have GPT partition table
You NOT USE LVM (you should)
You need to extend a partition on the main drive
You use Debian 8.x aka Jessie
