yes i am using a clone of the orignal VM. right now i have deleted the
orignal one and i have already performe a lot of work in the machine.
so creating a new one mean i have to work on the new one alot.

any suggestion how to come out of this issue. instead waisting of time
in installing a new VM.

so which way to go. bufforblot or KVM how can i troublshoot and how
can i fix this issue in debian lenny?

Thanks
