Hello: I create a centos7.6 virtual machine which use 3.10.0-957 kernel，using pci passthrough to support nvme device； and I found interrupt can not distribute to target CPU which in smp_affinity set，the problem solved when I update kernel to 5.0.20,is anyone can tell me how to solve this problem without updating kernel??
thanks advance!!

There is an NVMe bug that impacts some machines that should be fixed soon. Others have been fixed.
You can first try the latest c7 kernel (currently kernel-3.10.0-957.21.3.el7.x86_64.rpm)
You could also use one of our experimental kernels:
