Public bug reported:

I tried to run VM with the docs, 
http://wiki.openstack.org/NovaInstall
and
http://github.com/vishvananda/novascript
the docs say using screen tools, but I tried with nohup and saved all the logs to files for error tracking.

anyway, failed when runnig euca-run-instances.

The nova-compute log messages is as follows:
===============================================

===============================================

and.. libvirt log is like this.
===============================================

chardev: opening backend "file" failed
===============================================

so I tried to run the kvm command directly in command line..
but errors like this.. and kvm didn't run.
===============================================
TUNGETIFF ioctl() failed: Bad file descriptor
TUNSETOFFLOAD ioctl() failed: Bad file descriptor
qemu: could not open disk image console=ttyS0: No such file or directory
===============================================

so I changed -append option 
from -append root=/dev/vda1 console=ttyS0
to -append 'root=/dev/vda1 console=ttyS0'
and tried again...
so the messages "qemu: could not open disk image console=ttyS0: No such file or directory" disappeared...
(but TUNGETIFF and TUNSETOFFLOAD related messages was still there.. 
I guess it is relaged with -net tap blabla option. am I wrong?)
and It seemed that kvm was running..

So, I updated append option from $NOVA_DIR/nova/nova/virt/libvirt.qemu.xml.template  
and restart all the nova modules..

but same errors again...

I did search the bugs list about euca-run-instances problems, but my
situation wasn't there..

What's wrong with my test and machine ?
QEMU or KVM env?
