Do you mean "we can't migrate a TCG A15" ? That would be a problem. Or do you mean "we can't migrate a KVM A15" ? That's entirely expected when we drop support for KVM A15 :-) Or do you mean "migration from KVM to TCG doesn't work?" That's a pre-existing thing I don't expect to work (we don't put anything in to stop it working, but I'm pretty sure there will be a bunch of things that mean it doesn't in practice work.) > So we need both 1/ revert 82bf7ae84ce and 2/ be sure the kernel > support 32-bit host... Am I missing something? We're definitely not reverting 82bf7ae84ce if we can avoid it... thanks -- PMM
