Live migration Error restore failed

[Mou123]

Tried to migrate container with platform having different processor.
Please find the cpu info of the target and source Macines

Migration Error :

Hi,

This can't ever work in the general case, and so I think the error you got here was appropriate. I'll mark this as invalid for now, but please re-open if you think there is a way to do this for this particular CPU feature.
