Hi, I was trying to run qemu with spdk, referring to http://www.spdk.io/doc/vhost.html#vhost_qemu_config
Everything went well since I had already set up hugepages, vfio, vhost targets, vhost-scsi device(vhost-block was also tested), etc, without errors or warnings reported. But at the last step to run qemu, the process would somehow hang. And its cpu busy remained 100%. I used `perf top -p` to monitor the process activity, 18.28% [kernel] [k] vmx_vcpu_run 3.06% [kernel] [k] vcpu_enter_guest 3.05% [kernel] [k] system_call_after_swapgs Do you have any ideas about what happened here? Test environment: latest CentOS 7 kernel, nvme ssd, spdk v18.01.x, dpdk 17.11.1, qemu 2.12.0-rc2. Detail log is attached within this mail. Thanks, Bob
