#poweroff



3. try to stat from cmd xm create
#cd /OVS/..../../..
#xm create vm.cfg -c

i cant get the grub menu , but i cant get kernel msg , mean that some thing wrong on setting kernel line ...

4. poweroff the virtual machine
#poweroff

5. add serial = 'pty' to vm.cfg and poweron

#xm create vm.cfg -c

still cant get kernel bootup msg & login prompt .
