I try this in rdma env. also get this error even if not use --tunnelled # virsh migrate --live rhel7.3 qemu+ssh://192.10.10.1/system --migrateuri rdma://192.10.10.1 --verbose --postcopy --postcopy-after-precopy error: internal error: qemu unexpectedly closed the monitor: warning: host doesn't support requested feature: CPUID.01H:EDX.ds [bit 21] warning: host doesn't support requested feature: CPUID.01H:EDX.acpi [bit 22] warning: host doesn't support requested feature: CPUID.01H:EDX.ht [bit 28] warning: host doesn't support requested feature: CPUID.01H:EDX.tm [bit 29] warning: host doesn't support requested feature: CPUID.01H:EDX.pbe [bit 31] warning: host doesn't support requested feature: CPUID.01H:ECX.dtes64 [bit 2] warning: host doesn't support requested feature: CPUID.01H:ECX.monitor [bit 3] warning: host doesn't support requested feature: CPUID.01H:ECX.ds_cpl [bit 4] warning: host doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5] warning: host doesn't support requested feature: CPUID.01H:ECX.smx [bit 6] warning: host doesn't support requested feature: CPUID.01H:ECX.est [bit 7] warning: host doesn't support requested feature: CPUID.01H:ECX.tm2 [bit 8] warning: host doesn't support requested feature: CPUID.01H:ECX.xtpr [bi check qemu log : warning: host doesn't support requested feature: CPUID.01H:ECX.osxsave [bit 27] dest_init RDMA Device opened: kernel name mlx4_0 uverbs device name uverbs0, infiniband_verbs class device path /sys/class/infiniband_verbs/uverbs0, infiniband class device path /sys/class/infiniband/mlx4_0, transport: (1) Infiniband ibv_poll_cq wc.status=12 transport retry counter exceeded! ibv_poll_cq wrid=CONTROL SEND! 2016-09-21T08:40:22.926841Z qemu-kvm: rdma migration: send polling control error 2016-09-21T08:40:22.926860Z qemu-kvm: Failed to send control buffer! 2016-09-21T08:40:22.926871Z qemu-kvm: RDMA is in an error state waiting migration to abort! 2016-09-21T08:40:22.926879Z qemu-kvm: Not a migration stream 2016-09-21T08:40:22.926888Z qemu-kvm: Early error.

qemu: Report tunnelled post-copy migration as unsupported
Post-copy migration needs bi-directional communication between the
source and the destination QEMU processes, which is not supported by
tunnelled migration.
