-- Install the oracle virtual box (ex. 4.2.0)
-- Create a new v.machine with the settings for your os/2 warp version
ex.:
Name(anything): os2warp
Type: IBM OS/2
Version (the version that you are installing - 4 in my case): OS/2 Warp 4
-- Add one Disk and one Floppy as storage(s) for the virtual machine. Add a CD/DVD drive if you want to install a bit faster (see below).
-- extract the os2warp.iso so that you can use the dsk images for the installation (located in \DISKIMGS\OS2\35\)
-- Load in the floppy device the disk0.dsk and swap when requested by the os2 setup.
-- when the setup asks for the floppy 1 (after 0) use the DISK1_CD.DSK as floppy and remember to put the CD or load the cd iso image in the, virtual or real, cd drive
-- Choose "easy installation" if you don't need particular things.
When you the "Fdisk" application appears it can show you that the first disk is corrupted. Just go ahead and press enter.
press tab and press -> (right) to choose your disk.
Avoid the 1024kb that is the floppy disk -- that should be type 83 and "startable".
Your destination disk should be also with free space if not previously formatted.
Once you are in the disk page you need to press tab to choose your partition.
Press "Enter" and if there's no partition choose "create partition" and "primary partition".
If you are going to use more than one os (ex. os2+dos) on the same disk create the first partition of 1mb where you are going to install the boot manager.
See those faqs for more informations:
http://www.mit.edu/activities/os2/faq/os2faq0403.html
-- Create the first primary partition of 500mb where os/2 warp will reside and (press Enter)
-- Set the partition as startable and as Installable (!!Important).
The first partition must be smaller than 512mb (I've personally used 256mb) due to *old* bios restrictions.Fdisk will assign automatically the C: drive letter.
"Also, on many PCs, because of BIOS restrictions, your startable (primary) partition must be physically located entirely below the 1024th cylinder on your hard disk (or, roughly speaking, it must be no larger than about 511 MB)" (as already stated in the previously linked faqs).
Another good page is suggesting, with far more useful informations,
http://pclt.cis.yale.edu/pclt/BOOT/OS2.HTM
-- press f3 and exit
it could happen that the system doesn't recognize your primary partition even if you've done everything correctly. Just exit anyway and let the system restart. It should recognize your partition and start the regular installation (from floppy3).
if something goes wrong while formatting (red screen) restart (ctrl+alt+canc), choose advanced installation and try to reformat.
In case of other problems try to repartition with gparted (gparted live iso linux http://gparted.org/download.php) in fat16.
-- (If you want) Add a second "extended" partition that will fill all the remaining data and d: will be assigned automatically.
-- continue the setup
-- hit "enter" at the end of the installation process and restart

Errors:
OS/2!! SYS02025
OS/2!! SYS02027
Those errors are common if you are trying to use a non IBM machine, if the boot sector is corrupted (as I can read from the various docs), if there are HDD issues or if you are running non fully startable floppies.

To solve the problem in virtualbox just make sure to run the first floppy and switch floppy as needed from the current virtual machine without closing the v.m. window (check the devices in the toolbar/menu) and make sure that you have selected the correct OS/2 system when you have created the vm.
