Wei,
Can you better explain what you're trying to do, and what is your
environment?
I have added a line to boot.py:
diff --git a/generic/tests/boot.py b/generic/tests/boot.py
index bf4ddc9..2176493 100644
--- a/generic/tests/boot.py
+++ b/generic/tests/boot.py
@@ -23,6 +23,7 @@ def run(test, params, env):
timeout = float(params.get("login_timeout", 240))
vms = env.get_all_vms()
for vm in vms:
+ logging.info("VM IP address: %s", vm.get_address(0))
error.context("Try to log into guest '%s'." % vm.name,
logging.info)
session = vm.wait_for_login(timeout=timeout)
session.close()
And got the following result:
...
2016-05-30 10:17:25,036 qemu_monitor L0286 DEBUG| (monitor hmp1)
Sending command 'cont'
2016-05-30 10:17:25,037 qemu_monitor L0714 DEBUG| Send command: cont
2016-05-30 10:17:25,044 boot L0026 INFO | VM IP address:
127.0.0.1
2016-05-30 10:17:25,044 error L0085 INFO | Context: Try to
log into guest 'avocado-vt-vm1'.
...
This IP address is actually accurate because for this run I used user
level networking (the default setup).
