They are real ultra rapid,what can I do?

What do you think could we say if we have no infos about your configuration?

Whats the hardware, the guest configuration and what are the guests doing?

Ok,sorry...
The laptop is a Acer Aspire 7745G 2,53Ghz 8G memory.
I have assigned 1024mB 8each) memory to the guesst.
everything just moving the mouse pointer is slow and to open a menu takes forever.

Have you installed guest additions.

It takes 5-10 minutes to boot Fedora and when trying to install guest additions,I choose autorun nothing happens.

Post the exact and full guest configuration and the log file.

Where do I find the logfile?

In the directory where the guest is (the vdi file).

In the "machines" folder I do not find any files for Fedora,but all other dists I have installed,strange..I will fiddle around and see if I can get it to work.

What you can try: play with the settings. Enable/Disable IOAPIC, VT.

Where do I do that?

In the guest settings. Mark the machine in the VBOX GUI and call the change function. Look under the system tab.

the autorun feature of guest addition do not work in fedora, as you need to bee root to run the script.

open a console, switch to root, run the install script.
