I'm sure that the guest runs normally before saving. See the pictures attached in detail. Reproduce steps: ---------------- 1.create a guest: qemu-img create -b /share/xvs/img/app/ia32e_SMP.img -f qcow2 /root/test0320.img qemu-system-x86_64 -m 256 -net nic,macaddr=00:16:3e:06:8a:08,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /root/test0320.img 2.save the guest: on qemu monitor: migrate "exec:dd of=/root/test-save.img" 3.quit from qemu: "q" command on qemu monitor 4.restore from img just saved: qemu-system-x86_64 -m 256 -net nic,macaddr=00:16:3e:06:8a:08,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -incoming=/roo/test-save.img 5.see dmesg in restored guest, you'll find some I/O errors. And run some commands such as "ps", "touch","reboot" and so on. Then some I/O errors appear.
