[Qemu-devel] [Bug 1243287] Re: [KVM/QEMU][ARM][SAUCY] fails to boot cloud-image due to host kvm fail

[Scott Moser]

I just worked around this in cloud-init by disabling the smartOS datasource if 
the uname arch is arm* or aarch*

  error: kvm run failed Function not implemented

  /usr/lib/python2.7/dist-
  packages/cloudinit/sources/DataSourceAltCloud.py assumes that
  dmidecode command is availabe (ie it assumes that system is x86) on
  arm systems there is no dmidecode command so host kvm fails with the
  message "error: kvm run failed Function not implemented"

  The patch makes get_cloud_type() function return with UNKNOWN for ARM
  systems.

  I was able to boot the cloud-image on ARM after applying this change.
