Hi Gleb,

Yes, I am always got this error message. I feel these messages are
from kernel. Till today I am not able to launch the with full
virtualization support. I am able to launch with the -no-kvm option
to the above command-line. But still I can see the same messages.I am
connected to the target with ssh.

After connecting the monitor and modifying command line for
kernel(vga=0x) behavior qemu-kvm similar as below

A black screen with "VGA Blank mode" message in the middle.

I saw a message from Avi Kitty saying that "The guest runs the vga
vios and hangs. Please try with a production
processor"

from the link http://comments.gmane.org/gmane.comp.emulators.kvm.devel/45870

Thanks
