Description Chris Smith 2008-11-21 01:03:34 UTC

genkernel kernel, 2.6.25-gentoo-r9, provided .config has

  CONFIG_HAVE_KVM=y

provided use flags are modules -havekernel, attempt to emerge kvm says

  [ebuild     U ] app-emulation/kvm-79 [78] USE="-havekernel*" 

   * ERROR: app-emulation/kvm-79 failed.
   * Call stack:
   *               ebuild.sh, line   49:  Called pkg_setup
   *           kvm-79.ebuild, line   63:  Called die
   * The specific snippet of code:
   *   			die "KVM support not detected!"

Adding the line 
  CONFIG_HAVE_KVM=y
+ CONFIG_KVM=y

produces a successful build.





Reproducible: Always

CONFIG_HAVE_KVM isn't the config you need.  You actually have to build the kvm module itself (CONFIG_KVM) to get some symbols built in that kvm needs to have to build *it's* modules.  I don't think a standard genkernel provided .config is sufficient, hence the check.
