[Xen-devel] Error after running pygrub with xen 4.4-rc2

[M A Young <m.a.young@xxxxxxxxxxxx>]

I get the following error after running pygrub when launching a guest with 
xen 4.4-rc2.
xenconsole: Could not open tty `': No such file or directory
libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console 
child [0] exited with error status 2
After this the boot continues normally, but once the console exits the tty 
settings are wrong and key presses aren't echoed. I believe the error 
above is from a xenconsole session launched when pygrub is, and this exits 
because the guest generally hasn't started. A second run of xenconsole 
serves the console output after that. I have occasionally noticed with 
this and earlier xen versions that I have to press ^] after pygrub 
finishes before the boot continues, so I would guess that in some cases 
the first xenconsole run lasts long enough to get a console connection 
which has to be ended before the boot proceeds. Hence I suspect the 
behaviour hasn't changed in this version, and only the error message is 
new.
