The following test case does local migration 3 times in a loop. I
currently see the following error output on x86-64 (only!) inside the
guest (change debugMe in line 68 of xm-test/lib/XmTestLib/Console.py to
True):

+# Tests for xm migrate
+# 1) Create domain, verify it's up with console
+# 2) live migrate the domain to localhost
+# 3) verify it's migrated, see that it has a new domain ID
+# 4) verify it's still working properly by running a command on it
+# 5) jump to 2 and do local migration 3 times
