Abstract
Techniques for in-place live migration of guest domain compute instances are described. A secondary host domain, which may be a patched version of an initial host domain, is launched on a computing device in a candidate host domain role or as a guest domain with escalated privileges. Existing guest domains are live migrated within the computing device to utilize the secondary host domain while the initial host domain continues to serve guest domains that have not yet been migrated. When all guest domains have been migrated, the initial host domain may be terminated, resulting in a patched computing device without network-based failures or noticeable service degradation for the guest domains, and while allowing existing guest domain workflows and network connections to continue unaffected.
