Manually Creating Xen Disk Block Devices in /dev

On newer distros normally udev will create these devices but in some cases it doesnt know how to. Our distros are deployed with the devices already created so that it's not a problem. If your building your own distro or managed to foobar you /dev directory you may need to create the xvda, xvdb, xvdc… devices. Below shows how to do this.

# mknod /dev/xvda b 202 0
# mknod /dev/xvdb b 202 16
# mknod /dev/xvdc b 202 32
# mknod /dev/xvdd b 202 48
# mknod /dev/xvde b 202 64
# mknod /dev/xvdf b 202 80
# mknod /dev/xvdg b 202 96
# mknod /dev/xvdh b 202 112
