Bug Description
When installing 12.04 server (amd64, but shouldn't matter), and one selects "Guided - use entire disk and setup LVM", the default logical volume name uses the hostname. For instance, if I use the hostname "core", this causes problems: when selecting write changes to disk, the error appears:
"Unexpected error while creating volume group"
"Autopartitioning using LVM failed because an error occurred while creating the volume group"
"Check /var/log/syslog ..."
Output from syslog:
Apr 11 09:49:35 partman: Reading all physical volumes. This may take a while...
Apr 11 09:49:35 partman-lvm:
Apr 11 09:49:35 partman-lvm: No volume groups found
Apr 11 09:49:35 partman-lvm:
Apr 11 09:50:19 partman-lvm: Physical volume "/dev/sda5" successfully created
Apr 11 09:50:19 partman-lvm:
Apr 11 09:50:19 partman-lvm: /dev/core: already exists in filesystem

Apr 11 09:50:19 partman-lvm:
Apr 11 09:50:19 partman-lvm: New volume group name "core" is invalid
Apr 11 09:50:19 partman-lvm:
Apr 11 09:50:19 partman-lvm:
Apr 11 09:50:19 partman-lvm: Run `vgcreate --help' for more information.
Of course, since /dev/core already exists, it fails.
This breaks installation, but isn't clear to the user why it is happening. It's especially confusing as it is the default
recommended choice during install.
A solution - the volume name selection should append something distinct to avoid conflicting with the device name, for instance: -vg or -lv.
