yes, we occasionally see qemu main thread hangs and VM stuck in in-shutdown
state on aarch64 platform. So this could happen with I/O threads.
Thanks for confirming! Have you managed to test the final version of
the patches? It would be great to include test results.
Yes, I did the test with your latest patches on both aarch64 and
x86 platform.Test results show that the hang has been fixed. Thanks.
