• Fix blktap data access alignment
  
• Do not unpause domain after taking core
  
• Persist device model PID across restarts
  
• Pass internal libxc return value back to caller
  
• Fix passing of domid to libxc from python IOport & IRQ controllers
  
• Do not try to balloon more than physical RAM
  
• Add blktap sub-type checks
  
• Respect nographics request for HVM
  
• Put xenstored database on tmpfs
  
• Prefer grub.conf in pygrub
  
• Do not throw errors when listing domain
