Restoring Your USB Key partition to it's original state
After having tooled around with a USB Linux version using your multi partitioned flash pen drive, you might find it necessary to revert it back to a single fat partition (restore the flash pen drive to it's original state) that can again be read by all computers.

Then? I need to increase the partition map for my disk:
What did I do in fdisk? I deleted the partition, and then recreated it with the new available blocks. Of course the machine was running at the time. What is life without a few risks? But I have to ask myself, why doesn't fdisk have a resize command? I swear that tool hasn't changed in well over a decade.
I am running LVM so then I had to:
And finally since the filesystem is ext3:
So why post all of this here? For one it took me a while to figure it out, so I now have a record.
The other reason is to complain about virt-manager. The GUI, hell the command line controller, could have done all of this for me. The steps to increase a partition are quite byzantine and frankly I can see the entire "pay for time" equation pushing someone into just wanting to buy VMWare.
It works :)

pvresize /dev/xvda2
lvresize -L +5G /dev/VolGroup00/LogVol00
And finally since the filesystem is ext3:
e2fsck -f /dev/mapper/VolGroup00-LogVol00
resize2fs /dev/mapper/VolGroup00-LogVol00
