[Xen-devel] xenconsole: Could not read tty from store: No such file or directory

[李巍 <bupt_liwei@xxxxxxxx>]

Hi,
    I build xen-3.4.2 with VT-x support on ubuntu9.10 amd64-server.The machine boots ok and I start xend manually.I encounter the following problem with guest creation: $xm create -c /opt/vm/appscale1/xen.conf
Using config file "/opt/vm/appscale1/xen.conf",start domain appscale1,I get the error:"xenconsole:Could not read tty from store: No such file or directory".The guest is created but remains blocked.Using the command:xm console  <domU Id> does not resolve the problem.I try to restart xend and xendconsole,but the error still exists.
    Below is information about guest config file and xen configuration.
Please let me know what is needed to resolve the problem,thanks!
