Hi,

after using VirtualBox successfull on my old win xp pc with several guests, I installed it on my new win7 pc.

I installed an ubuntu and a zentyal server, using an iso as virtual cd; no problems.

On the first day, all worked fine after install, too: restart the virtual servers, work with them ...

But since yesterday I get a guru meditation in 9 out of 10 times.

I deleted the whole server installations. deinstalled VirtualBox. Re-Installed. New virtual servers build, install from the iso worked fine. But after first restart: guru meditation Sometimes 2 out of 10, the virtual server freezes only with a black screen and a prompt in the top-left corner.

I tried it with only 512MB RAM, with 2500MB, 1000MB ...
any idea?

Looks like the same issue already reported to bugtracker https://www.virtualbox.org/ticket/12219 Please attach your log file there.

OK, done so.

Is there any known reason for the problem? Or a workaraound?

No clue. That's why I sent you to bug tracker. These started cropping up with version 4.3 and so far no one here has figured out the cause.

are there any new experiences with the latest version?
