+# uXen : Open Source type-2 hypervisor support

+## uxen-guest-tools : software for within guest VMs, kernel modules
+
+* uxenhc        : hypercall driver
+* uxenfb        : framebuffer driver
+* uxenhid       : Human Input Device driver
+* uxennet       : virtual network device driver
+* uxenplatform  : uXen platform device driver
+* uxenstor      : virtual storage device driver
+* uxenv4vlib    : v4v, Hypervisor-Mediated data eXchange
+* v4vvsock      : v4v vsock virtual network device driver
+* v4vtest       : basic v4v vsock test
+
+To produce a bootable VM disk image file:
+
+    wic create directdisk -e uxen-guest-image-minimal
+
+To test, copy the .direct file that wic produces to the host with uXen installed and write the following to a new file: `linux-vm.json`. Update the file path within it to point to your wic-generated disk image:
+
+    {
+      "name" : "Linux Virtual Machine",
+      "boot-order" : "c",
+      "block" :
+        { "id": "ich0", "proto" : "raw", "xsnapshot" : true,
+          "path" : "c:/Users/Yocto/directdisk-202001010100-sda.direct" },
+      "memory" : 768,
+      "net" : { "type" : "nic", "model" : "e1000" },
+      "hpet" : 1,
+      "vcpus" : 1,
+      "use-v4v-net" : 1,
+      "v4v-storage" : true,
+
+      "" : ""
+    }
+
+and then boot it:
+
+    uxendm -F linux-vm.json
