[Bug 688085] Re: Guest kernel hang during boot when KVM is active on i386 host

[Serge Hallyn]

** Description changed:

  Binary package hint: qemu
  
  Guest kernel hang during boot when KVM is active on i386 host
  
- See the patch. 
+ See the patch.
  http://www.spinics.net/lists/kvm/msg40800.html
  
  How to reproduce:
  1. install Maversick x86 (not amd64)
  2. ensure you have  kvm support in processor
  3. kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae
  4. kvm -no-kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae works OK.
+ 
+ SRU Justification:
+ Impact: Users cannot boot KVM guests on i386 hosts
+ 2. How bug addressed:  The upstream commit at http://www.spinics.net/lists/kvm/msg40800.html fixed it
+ 3. Patch:  A kernel patch is attached to this bug.
+ 4. Reproduce: boot an i386 kernel on a kvm-capable host.  Try to boot a kvm guest.
+ 5. Regression potential: since this is cherrypicking a commit from a future upstream which had already been changed, regression is possible.  However if there is a regression, it should only affect users of KVM on i386 hosts, which currently fail anyway.
