Today,I clone a VM in the XenCenter.I want to log into the new VM to configure ip and so on,But I had forgotten the original VM’s root password.So I can not log into the new one.
There are at least two kinds of way to reset the root password.One way is making the new VM boot from cdrom. I think it is too complicated to do that.The other way is editing grub’s boot option and making the VM boot into single user mode.It’s easy to do that.Follow this step:choose the new VM–>Shut down the new VM–>click the right mouse button–>Properties–>Startup Options–>OS Boot Parameters–>add single after utf8,the conten after edited is graphical utf8 single.Start the new VM again,it boot into single user mode,now we can change root password.
At last,shut down the VM,change OS Boot Parameters’s content to graphical utf8,start the new VM.
