[Xen-users] Ubuntu 12.04 as a PV error: xenconsole: Could not read tty from store

[Konstantin <konstantin@xxxxxxxx>]

Hi,

When I'm trying to start Ubuntu server 12.04 installation on one of my 
Dom0 I got an error:
# xl -vvv create /etc/xen/vm-confs/test -c
...
xenconsole: Could not read tty from store: No such file or directory
libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console 
child [0] exited with error status 2
And domU stops at that point. On another it works without a problem. I 
believe that I'm using the same Xen binary 4.4.2 on both of my Dom0s 
compiled with the same flags. Ubuntu Trusty 14.04 installation starts 
without a problem on both.
Kernel and initrd are the same on both Dom0 and were downloaded from 
here:
http://us.archive.ubuntu.com/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/

Xenconsoled is running and I can successfully connect to any of my 
existing PV servers.

PV configuration look pretty simple:

Any ideas, guys?
