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?
