<p>Quintela: </p> <hr /> <div>This page reports qemu migration ToDo list. It includes:<br /> <br /> == Support for big memory machine ==<br /> <br /> Current code fails with 64GB/256GB guests. Things that need to improve are:<br /> <br /> * dirty migration bitmap: we need to split it from normal TCG bitmap<br /> (bitmap has 16bits by page of memory, and kvm only ever uses <br /> the migration bit)<br /> * TLB handling: related with previous one, kvm don't need TLB handling in qemu.<br /> * detecting if we converge/not during migration<br /> * improve measurements to be able to give good information to management<br /> <br /> <br /> <br /> == Port all missing cpus to VMState ==<br /> <br /> This means that nothing out of hw/ will use the old qemu migration stuff.<br /> <br /> == Port all missing devices to VMState ==<br /> <br /> We need to finish this one to be able to change the migration implementation/protocal. Current problems include that we do too many copies to be able to saturate a 10G network.</div>
