# Can be used within the VS Code dev container to debug

### Create PXE network

```
virsh net-define ipxeboot.xml

virsh net-start ipxeboot

virsh net-autostart ipxeboot
```

### Start PXE machine

```
virt-install -n rocky --memory 4096 --vcpus 8 \
    --pxe --disk size=25,bus=virtio --network network=ipxeboot,model=virtio \
    --input tablet --os-variant rhel9.0 \
    --noautoconsole
```

```
virt-install -n rocky --memory 512 --vcpus 1 \
 --pxe --disk size=5,bus=virtio --network network=alpineipxeboot,model=virtio \
 --input tablet --os-variant id=http://alpinelinux.org/alpinelinux/3.19 \
 --noautoconsole
```

### Inside a virt-install VM

```

### Currently not needed, but if need in the future - systemctl/docker during build:

```
docker buildx create --use --name insecure-builder --buildkitd-flags '--allow-insecure-entitlement security.insecure'
docker buildx use insecure-builder
docker buildx build -t emanuilov/dev --load --allow security.insecure .
docker buildx use default
```
