Claim 15:
16. One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors cause the one or more processors to:
obtain, at a first virtualization server prior to a launch of a compute instance, (a) a first virtualized security device initialization data set from a first source, and (b) a second virtualized security device initialization data set from a second source;
modify, after performing one or more cryptographic operations at the first virtualization server, a value of a data item included in the second virtualized security device initialization data set, wherein the one or more cryptographic operations include generating a particular cryptographic artifact used by the compute instance, wherein the particular cryptographic artifact is generated by a first virtualized security device initialized at the first virtualization server using the first virtualized security device initialization data set and the second virtualized security device initialization data set; and
perform one or more additional cryptographic operations at a second virtualization server to which the compute instance has been migrated from the first virtualization server, wherein the one or more additional cryptographic operations include including generating another cryptographic artifact used by the compute instance, wherein the other cryptographic artifact is generated by a second virtualized security device instantiated at the second virtualization server, and wherein the second virtualized security device is initialized using at least the modified value of the data item.
