Fast and correct performance recovery of operating systems using a virtual machine monitor

Kenichi Kourai
2011 SIGPLAN notices  
The warm-cache reboot preserves the page cache during the reboot and enables an operating system to restore it after the reboot, with the help of a virtual machine monitor (VMM).  ...  Rebooting an operating system is a final but effective recovery technique. However, the system performance largely degrades just after the reboot due to the page cache being lost in the main memory.  ...  Worse, if the operating system runs in a virtual machine (VM), such cache misses may greatly affect the whole system performance because disks are shared between VMs.  ...
