[Xen-devel] [PATCH][XM-TEST] Add hping to the ramdisk

  • To: Xen Developers <xen-devel@xxxxxxxxxxxxxxxxxxx>
  • From: Dan Smith <danms@xxxxxxxxxx>
  • Date: Thu, 17 Nov 2005 13:58:11 -0800
  • Delivery-date: Thu, 17 Nov 2005 21:58:11 +0000
  • List-id: Xen developer discussion <xen-devel.lists.xensource.com>
Add hping to the ramdisk.  Also, do some very simple versioning.
This is the first change to the ramdisk since v0.1.0.  So, we now build
the image as initrd-X.Y.img, and link initrd.img to it.  This lets us
have a few checks to make sure that people rebuild their ramdisks when
necessary.

 NB: If you have the initrd.img from another installation of xm-test,
 you can copy it into the ramdisk directory to eliminate the need to
 rebuild it.  If you do this, there is no need to run 'make' again.
-Simply copy the initrd.img file into ramdisk/ and then run the
-runtest.sh script.  Note that in general, you should not attempt to
-use a ramdisk from a previous minor version of xm-test (i.e., don't
-use a ramdisk from 0.4.0 with 0.5.0.  0.5.0 should work for 0.5.3
-though)
+Simply copy the initrd-X.Y.img file into ramdisk/ and then run:
+
+   # make existing
+
+This will set up the link so that xm-test will use the existing
+ramdisk.  Next, just run "runtest.sh" normally.  Note that in general,
+you should not attempt to use a ramdisk from a previous minor version
+of xm-test (i.e., don't use a ramdisk from 0.4.0 with 0.5.0.  0.5.0
