#3202 fixed Remount recently unmounted media does not mount it => Fixed in SVN Sasquatch
Description

If you unmount an ISO from the Guest, you can't mount it again for a while. You usually have to shutdown the VM before the actual ISO is in released state, or wait a long time (an hour or more). When selecting an ISO image from the Media Manager, it will show it's state as 'attached', while the Disc Icon in the VB GUI doesn't reflect this. If a different ISO is mounted, it works, but then both ISOs are shown as mounted and as soon as the second ISO is unmounted, it too cannot be mounted again.

A probably related issue is when installing an OS (tested with Linux) that 'ejects' it's media after installation, you can't boot from it again until you shutdown the VM.

#3203 fixed Opensuse 11.1 fail bootup with Virtualbox 2.1.2 with gdmdisplay error -> unable to reproduce, possibly fixed in SVN aven
Description

I have used Virtualbox 2.1 before when I installed Opensuse 11.1 on a Ubuntu 8.10 host but I uninstalled the Opensuse install after a while. I upgraded to Virtualbox 2.1.2 and tried to reinstall Opensuse again, it started to have this gdmdisplay error.

No matter if it was with KDE or Gnome or a different host machine like Windows Vista, it gave a gdmdisplay error at startup. It did not have this error in the previous version but, Opensuse booted up fine in failsafe mode for some reason.

#3204 fixed Performance improvement on Windows XP SP3 host OS/fixed in 2.1.4 gmuthu
Description

It will be great if the CPU utilization (while running a guest OS) on a Windows (XP SP3) host OS can be improved further.

My PC is running Pentium 4 CPU 2.4 GHz with 2 GB of memory (pretty low-end by today's standards, I know). I primarily use Virtualbox to test out Solaris/OpenSolaris.

After starting a guest OS (I run only one at a time), the CPU util. shoots upto 100% and remains there (observed thru taskmanager). It hardly comes down. The guest OS is assigned 1 GB of RAM (not worried about the guest OS memory consumption as it is expected).

Why I think the performance can be improved: Vmware Server 2.0. While during the booting of the guest OS, the cpu util too reaches 100%, but it drops down to 30-40% range once the OS is up.

If this can be achieved with Vbox, it will be great.

I have not tried 2.1.2 yet.
