It has no specific thought to ARM migration, but an ARM virtual machine is exactly like an x86 HVM domain (from the toolstacks point of view), other than the Qemu record. With any luck, no new additions to the spec will be needed, but the spec is trivially extendible if required.IMO, ARM uses PVH domain. Can you please let me know how to use your patches, I mean xl/xc commands to do migration (non-live/live) using your patches. Any debugging and testing support information would be helpful. Hi - apologises for the late reply. I have been on holiday.The patches series as available does make `xl save/restore/migrate` work, although the error handling leaves a lot to be desired. We (XenServer) are in the process of attempting to get everything upstream. The libxc side of things is definitely working and already shipped in XenServer 6.5 (We absolutely needed to support migrating between 32 and 64bit toolstacks, which was the primary reason for the rewrite). What sort of timescale are you looking for on this? I hope to have a new series posted soon, now that the datacopier subseries has been accepted. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
