Hi, Alex,
I've used your USB_RUN script to create an image file. I followed your instructions to prepare the USB stick. However, the USB stick cannot boot up. Unfortunately, I do not have access to a laptop with serial port so I am unable to get any logs. Can I check with you on your instructions (the mini-howto below) instead. Thanks. # # Make sure that the USB is not used - all partitions are un-mounted.
How should I prepare this USB stick, should it be formatted under a
particular filesystem (ext2, or FAT32)
No preparation. The image you copy with dd already contains a valid mbr + ext2 partition. So after the dd command, you should be able already to mount the ext2 partition. If this does not work - something is already odd - so make sure that mounting it already succeeds ! (Let's call it step 0).
Can I clarify the steps below are in sequential order
- dd operation
Yes
- fdisk operation - delete all partitions, then create a new partition
and then write to disk.
There should be exactly one partition to delete.
- Resizefs operation
Yes
- Mount partiton (I tried this but could not get a successful mount
until I create a filesystem using mke2fs. Is this step necessary ?)
The first 3 steps are ok. If the 4. step does not succeed something failed during re-partition and ext2 resize of the ext2 partition. Effectively you should see on the ext2 partition the very same content as after Step 0 (dd). The main goal of step 2-3 is to expand the ext2 partition over the whole USB stick - otherwise there is not enough place for the VM image.
Cheers,
Alex
