Zusammenfassung:According to aspects of the present disclosure, systems and methods can be provided to recover from memory errors that occur during or following a virtual machine migration. Methods, computer program products and/or systems are provided for handling memory error that perform the following operations: (i) obtaining a memory address that triggered an uncorrected error on a first host associated with a virtual machine migration; (ii) computing a page associated with the memory address; (iii) determining if a copy of the page associated with the memory address is available on a second host associated with the virtual machine migration; (iv) obtaining data from the copy of the page on the second host; and (v) generating a new page on the first host with the data obtained from the second host.
