BLKCACHE_IOERR on VBOX506, VM stopped with a grayng screen.

[Anchieri]

I have installed over my PC ASUS P5LD2-X/1333 with eCS-2b1 and
3GB of RAM the recent version of VBOX to test it with my Window 7 Professional 32bit.
After most trying I was able to install Win 7 pro and updating it with all Window updates (some 250 updates), during this time I have many case of this problem, resolved by me with a stop (with a save of state) and restart.
I attache the "Vbox.log" after this stop and a image (VBOX506-INF.jpg) with all the information on my vbox.

Are you sure that you have sufficient disk space? It looks that it had troubles with saving data to a disk image.

Also, this is strange:

00:00:03.427027 Host RAM: 2939MB total, 836MB available

-- You have 1500 MB allocated to a VM (I use 784 MB ram with win7 guest) but only 836 is available.

And this:

So, you have 30 SATA ports created? Why you need this?

I don't set this number, more likely is a number setted automatically by the system.
and for me three or four is sufficient, now I have set to 4.
I normally use the old VBOX 160 with Win-XP wich with 512MB work very well, with Win 7 I have noted that is difficult to set a number of MB for the VM I have used from 768MB to 1690MB and never I have succeeded, almost any of setting come with some degree of error, most low storage.
By now I have set VIRTLIMIT to 2944, can you give me a resonable solution that I can test?.
Thank you for your response,
G.M. Anchieri

I attach a image (VBOX-01.jpg) with the information on device attached to VM, as you can see we have more then 2GB of C: VDISK free.
