Require at least one console for LXC domain
A domain without a console quietly dies soon after start,
because we try to set /dev/null as a controlling TTY
2014-10-30 15:10:59.705+0000: 1: error : lxcContainerSetupFDs:283 :
ioctl(TIOCSCTTY) failed: Inappropriate ioctl for device
Report an error early instead of trying to start it.

git describe: v1.2.10-17-g44686f6
Verify this bug with libvirt-1.2.8-9.el7.x86_64.
1. Define a lxc guest without any console
# virsh -c lxc:/// dumpxml lxc-test
<domain type='lxc'>
<name>lxc-test</name>
<uuid>b637ffd5-0fcc-48fa-95f3-bbd0504d8643</uuid>
<memory unit='KiB'>1048576</memory>
<currentMemory unit='KiB'>1048576</currentMemory>
<vcpu placement='static'>1</vcpu>
<resource>
<partition>/machine</partition>
</resource>
<os>
<type arch='x86_64'>exe</type>
<init>/bin/sh</init>
</os>
<clock offset='utc'>
<timer name='rtc' tickpolicy='catchup'/>
<timer name='pit' tickpolicy='delay'/>
<timer name='hpet' present='no'/>
</clock>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<filesystem type='mount' accessmode='passthrough'>
<source dir='/'/>
<target dir='/'/>
</filesystem>
<interface type='network'>
<mac address='52:54:00:8f:13:eb'/>
<source network='default'/>
</interface>
</devices>
<seclabel type='none' model='selinux'/>
</domain>
2. Try to start lxc
# virsh -c lxc:/// start lxc-test
error: Failed to start domain lxc-test
error: unsupported configuration: At least one PTY console is required
The result is expected, so I will change this bug to VERIFIED status
