If you find your self creating a virtual machine and it crashes (and maybe your OS as well) during the installation. It might be something to do with the host I/O caching option.

I had this problem when the VDI file was on my RAID. I didn't experience problems if the VDI was on a single disk. Both disk had XFS partitions.

The trick... Go to your VM. Go to Settings > Storange > HDD controller (can be IDE/SATA/SCSI/SAS) and select "Use host I/O cache".

This should do the trick. If it doesn't the first time, maybe you get a error saying it cannot read/write to /dev/sda, power off your guest OS and power it on again. Now it should be working.
