Your issue might be that. 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?
