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 you're building your own distro or managed to fubar your /dev directory however, you may need to create the xvd[a-h] block devices manually. The
mknod commands below will (re)create these devices.
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
