Hi Everyone, Hope everyone is doing great. I have seen some live migration issues with qemu-4.2 when using multiFD. Signature of issue is something like this. 2022-10-01T09:57:53.972864Z qemu-kvm: failed to receive packet via multifd channel 0: multifd: received packet magic 5145564d expected 11223344
Basically default live migration channel packet is received on multiFD channel. I see a older patch explaining potential reason for this behavior. https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg05920.html > [PATCH 3/3] migration/multifd: fix potential wrong acception order of IO. But i see this patch was not merged. By looking at qemu master code, i could not find any other patch too which can handle this issue. So as per my understanding this is still a potential issue even in qemu master. I mainly wanted to check why this patch was dropped? Sorry if mis-understood something. It will be great if someone can provide some pointers on this. Thanks Manish Mishra
