"ssh" or "netstat" hangs even if I press "Ctrl+C" to interrupt. And I cannnot connect the guest using "ssh GustIP" from the host, though the sshd is still running in the guest. Reproduce steps: ---------------- 1.start a tcp daemon for migration: qemu-system-x86_64 -m 256 -smp 4 -incoming tcp:localhost:4444 -no-acpi -net nic,macaddr=00:16:3e:63:d5:90,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /root/lv.img 2.create a guest: qemu-system-x86_64 -m 256 -smp 4 -no-acpi -net nic,macaddr=00:16:3e:63:d5:90,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /root/lv.img 3.migration: migrate tcp:localhost:4444 4.run command in guest: ssh root@192.168.1.177
