DMTCP allegedly could do this with the help of plugin utilizing KVM kernel driver API - so why not also CRIU in theory (eg cant it be added - what is the blocking issue/design)? There is a publication describing DMTCP approach in detail: <span style="color: rgb(0, 0, 0); font-family: Arial, FreeSans, Helvetica, sans-serif; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 17px; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(240, 240, 240); display: inline !important; float: none;"> </span><a href="http://arxiv.org/pdf/1212.1787v1.pdf">http://arxiv.org/pdf/1212.1787v1.pdf</a><div><br></div><div>Having kind of hypervisor agnostic checkpointing/restore package would be a great opportunity to build homogeneous cloud HA services around it.</div><div><br></div><div>Kind regards,<br><div apple-content-edited="true">
