Add a check in eucalyptus-nc to verify that the target can run KVM

Etienne-

Hmm, this is a bit easier said than done.

We can't run kvm-ok directly, because the package that provides kvm-ok may be being installed at that time. Note that there's another bug where we're trying to get kvm-ok into the base system files and out of qemu-kvm, Bug #429443.

However, kvm-ok's real meat is a very simple grep of /proc/cpuinfo. That's certainly something that we can do.

I disagree with the concept of a "dialog box", or anything interactive that would hamper unattended installations.

But I can throw a warning message echo'd in the nc postinst, such that the message is at least logged *somewhere*.

This bug was fixed in the package eucalyptus - 1.6~bzr854-0ubuntu6

  * debian/control:
    - have eucalyptus-common depend on openssh-server and openssh-client,
      as these should really be installed on most any Eucalyptus system,
      LP: #411656
    - have eucalyptus-common recommend unzip, since Eucalyptus uses zip
      files for credentials, which may be needed on various systems,
      LP: #436876
    - recommend libpam that provides pam_motd, LP: #436199
    - conflict with apache2-mpm-itk, LP: #338344
  * debian/eucalyptus-common.postinst: configure VNET_DHCPDAEMON and
    VNET_DHCPUSER appropriately for default Ubuntu on initial install,
    LP: #364938

  [ Colin Watson ]
  * debian/control:
    - Make eucalyptus-nc explicitly depend on apache2-mpm-worker |
      apache2-mpm-prefork, since the NC requires that Apache be configured
      to only start a single child (LP: #338344).
