Part III Hypervisor-Independent Features

  • 15 Disk Cache Modes
  • 16 VM Guest Clock Settings
  • Keeping the correct time in a VM Guest is one of the more difficult aspects of virtualization. Keeping the correct time is especially important for network applications and is also a prerequisite to do a live migration of a VM Guest.

  • 17 libguestfs
  • Virtual Machines consist of disk images and definition files. Manually accessing and manipulating these guest components (outside of normal hypervisor processes) is possible, but inherently dangerous and risks compromising data integrity. libguestfs is a C library and a corresponding set of tools designed for safely accessing and modifying Virtual Machine disk images—outside of normal hypervisor processes, but without the risk normally associated with manual editing.
