Are you having problems simply creating and installing a system with LVM or can't boot after putting a system *on* LVM? Grub is not able to boot from an LVM partition, which is not limited to Ubuntu or other distros but a limitation in grub itself. If you have /boot (or your kernel, etc) on an LVM partiton it will not boot.
If it is simply creating an LVM enabled machine with grub and /boot on its own primary partition... this should be supported by the text and gui installers.
Please provide more information to better help us troubleshoot your issue.
