Comment 13 for bug 879710

Wanted to add a note -- Resolved my own recurring issue by switching from lucid to essentially any other release. Can confirm that both maverick and oneiric work for me, having changed only the release in the call to vmbuilder.
.i.e:

sudo vmbuilder kvm ubuntu -v --debug --suite=maverick --flavour=virtual --rootsize=4096 --swapsize=1024 --mem=388 --arch=i386 --user=system --pass=changemenow --components=main,universe,restricted --addpkg=acpid --addpkg=openssh-server -o --libvirt qemu:///system

works, where

sudo vmbuilder kvm ubuntu -v --debug --suite=lucid --flavour=virtual --rootsize=4096 --swapsize=1024 --mem=388 --arch=i386 --user=system --pass=changemenow --components=main,universe,restricted --addpkg=acpid --addpkg=openssh-server -o --libvirt qemu:///system

fails

Considering that I had the command line string working in early Feb (2012-02-03) and that Lucid . 4 (10.04.4) was released ~ Feb 16, I'd have to guess that changes involved therein are leading to issues with vmbuilder?
