kvm commit: a72e315c509376bbd1e121219c3ad9f23973923f
Guest hangs when I run command "ssh"/"netstat" using network after live
migration. "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
