Included in these tests are live migrations from 32bit toolstacks to 64bit toolstacks, using the python conversion script. Several corruption issues have been located and fixed, as well as many minor improvements. In addition, performance tests have been performed. After finding an initial regression, the code uas been tweaked to use writev() in preference to write() which vastly reduces the number of system calls performed. The performance is now better than the legacy code for all sizes of VM.Fantastic! .. snip..The code is presented here for comment/query/critism.My notes say: 'tmem and remus need work'. Is that addressed by this patchset or would that be further work? Thank you.tmem still completely outstanding. remus is being worked on by Yang (which is fantastic from my point of view). I believe this is a PoC apparently working? Do you mean a PoC of remus support on migration v2? If so, yes, I will post a RFC patch on this. BTW, will migration v2 be in Xen 4.5(both libxc and libxl side)? If it will be in Xen 4.5, will legacy migration be completely removed from 4.5 or both versions of migration will co-exist for a period? ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel -- Thanks, Yang. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
