摘要
A computer-implemented method for facilitating long-distance live migrations of virtual machines may include: 1) identifying a request for a live migration of a virtual machine from a primary site to a secondary site, the primary site including a primary storage device used for storage by the virtual machine being configured for active-passive replication to a secondary storage device at the secondary site, 2) initiating a failover of the active-passive replication from the primary storage device to the secondary storage device in response to the request, 3) intercepting each write attempt made by the virtual machine at the secondary site to the secondary storage device before completion of the failover, 4) buffering each intercepted write attempt, 5) determining that the failover is complete, and 6) applying each buffered write attempt to the secondary storage after determining that the failover is complete. Various other methods, systems, and computer-readable media are also disclosed.
