[Xen-devel] [PATCH] fix vmx domain creation fail with SDL from changset 7547

["Ling, Xiaofeng" <xiaofeng.ling@xxxxxxxxx>]

Fix the DISPLAY configration that breaks vmx domain creation with SDL on 
vncserver or remote X.
changeset 7547 add a judgement of opts.vals.display when getenv("DISPLAY"), 
because there is
a default value:localhost:0, that cause the judgement always true.
