## Virtualisation
To [see if hardware vms are enabled](https://www.cyberciti.biz/faq/linux-xen-vmware-kvm-intel-vt-amd-v-support/):
```bash
cat /proc/cpuinfo
```
and look for `lm` (for 64-bit cpu), `vmx` for intel or `svm` for amd.

To install kvm on ubuntu:
```bash
sudo apt-get install qemu-system
```

For the virtual machine manager
```bash
sudo apt-get install virt-manager
```

To make a qcow2 hard drive image:
```bash
qemu-img create -f qcow2 disk.img 4G
```

Examples to boot an image using qemu:
```bash
# From a floppy img
qemu-system-i386 -fda floppy.img -boot a
# Install to hard drive from cd image
qemu-system-i386 -cdrom cd.iso -hda myhdd.img -boot d -m 256 -localtime
```

### Running Linux Virtualised
Under Windows, most of the time, WSL does what I need, and so I use that due to its far better integration with the host. For other VM duties, under Windows, I use VirtualBox and under Linux I use KVM.
