kvm commit: a72e315c509376bbd1e121219c3ad9f23973923f
After restoring from saved img, some I/O errors appear in dmesg and
file system is read-only. 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.

this issue occurred again. So reopen this bug.
I use upstream kvm.git ef7c782ea and qemu-kvm.git 44755ea36.
The host is rhel6.1 with lastest kvm and qemu-kvm installed, and its file system type is ext4.
here's the dmesg info in rhel5u5 guest after being restored.

kvm commit: a72e315c509376bbd1e121219c3ad9f23973923f
After restoring from saved img, some I/O errors appear in dmesg and
file system is read-only. 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 -hda /root/test0320.img -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.
