Environment = XenHVM.
>Description:
Any attempt to create a new partition from within sysinstall causes the program to crash with a floating point exception.

This issue is also present in FreeBSD 8.X, even with the stock XENHVM kernel.

Seems I am also not alone with this problem:

I suspect also (based on the article in the above URL) that it is related to geometry information being bad or presented badly to fdisk.

I have free space on my primary disk which I wish to use and cannot because of this problem.

>How-To-Repeat:
Run FreeBSD 8.X or 9.0-BETA* in a Xen HVM environment and then Compile the XENHVM kernel. Run sysinstall and attempt to create a new partition, sysinstall crashes.
