Hi

My desktop connects the network through a proxy which makes the network
setup tricky for me, so I gave up this morning.

I'm now trying another approach by creating a image of ubuntu 12.04
(precise) and then copy the parsec files and ./create_checkpoint etc. into
my new image.
I first copy the content from parsecROI.img to my host with the help kpartx
command.

Now the problem is that when I copy the parsec folder from my host to the
new image, it doesn't have enough space.
I've tried to increase the rootsize option when invoking ubuntu-vm-builder
but the image size is the same as when it is set to 5120.
And after mounting, the image is a 4.1GB volume.
Here's my configuration:

[DEFAULT]
arch = amd64
suite = precise
rootsize = *10120 # I increased this but the raw image size doesn't change
compared with 5120*
addpkg = openssh-server, openssh-client, vim


Do you know how to increase the size of the image?

Many thanks
Wen
