virtualbox.org

I have created a vm by GUI localy, and installed an XP os on it. It run smoothly in GUI locally. But when I connect to the host by telnet, it could not be run by headless. and I found while in telnet, no vm was registered, there's nothing in "vboxmanage list vms" . and I also try to regist the vm manually, but it doen't work, I got " Failed calling virtualbox->openmachine (bstr(argv[0]), machine.asoutpara())at line 3155"
Can't I use the vm created by gui with telnet

Did you use the same user as you have the VM on? E.g., you can't access your VM from user A, if you log on to telnet with user B.

Yes, I set up the vm with administrator locally and login with it as well in telnet. It's quite strange I can't even register an existed vm manually.
