[Bug 1374612] Re: [FFE] add pc-1.0-precise machine type

[Serge Hallyn]

** Description changed:

+ =====================================
+ Impact: qemu VMs cannot be migrated from 12.04->14.04 hosts
+ Test Case: migrate a vm from p->t host, using disk on a NFS share.  On the 14.04 host, use
+ 	kvm -M pc-1.0-precise [...] -incoming tcp:0.0.0.0:5555
+ and on the 12.04 host use
+ 	kvm -M pc-1.0 [...] -monitor stdio
+ then on the monitor type
+ 	migrate tcp:0.0.0.0:5555
+ 
+ Regression Potential: This introduces a new machine type.  In precise it will make the new machine type the default, but it is identical to the old default.  In Trusty it is not the default.
+ =====================================
+ 
  Bug 1291321 shows that qemu VMs cannot be migrated from a host running
  12.04 to a host running 14.04.
  
  https://wiki.ubuntu.com/QemuPTMigration explains the proposed solution.
  As a part of this, we need to define the pc-1.0-precise machine type
  which can accept incoming migrations from pc-1.0 machines from a precise
  host.
  
  Since this machine type requires the old precise pxe-virtio rom, this
  bug is blocked on the FFE for the new ipxe-precise package, bug 1374617.
