Managing Live and Offline Migrations with Linux’s KVM

“As we all know, KVM is the Linux kernel’s built-in
virtualization solution. Using KVM, you can run virtual machines on
top of Linux without having to modify the operating system that’s
running under KVM. You can run Linux, Windows, and other operating
systems on top of Linux using KVM.

One of KVM’s most useful features is migrating guest operating
systems to different hosts. The type of migration we’re going to do
is temporary, so it’s perfect for temporary chores like hardware
maintenance or emergency load-balancing. You can keep your guest
running while it migrates, or have only a short downtime in an
offline migration.
