This page will document my expirience with Proxmox which you might think as web-based version of vz-tools.

This is somewhat interesting story, because I ended up migrating PVE installation on internal laptop disk to enable dual boot. First, I installed PVE on external USB drive (which wiped out mbr on internal disk, sic!) and than archived all files from it to move it to internal disk.

Installed system had following partitions:

/dev/mapper/pve-root on /mnt/pve type ext3 (rw)
/dev/sdb1 on /mnt/pve/boot type ext3 (rw)
/dev/mapper/pve-data on /mnt/pve/var/lib/vz type ext3 (rw)

So I re-created volume grup pve and logical volumes.

I have following partitions on my laptop:

root@tab:~# fdisk -l /dev/hda

Disk /dev/hda: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x3b7f0ef5

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        1305    10482381   83  Linux

/dev/hda3            1437        1567     1052257+  82  Linux swap / Solaris

/dev/hda7            6790        9400    20972826   83  Linux
/dev/hda8            9401       12161    22177701   83  Linux

and I wanted to use /dev/hda2 as boot and /dev/hda5 for lvm

lvm

root@tab:~# pvcreate /dev/hda5
  Physical volume "/dev/hda5" successfully created
root@tab:~# vgcreate pve /dev/hda5 
  Volume group "pve" successfully created
root@tab:~# lvcreate -L 1G -n root pve
  Logical volume "root" created
root@tab:~# lvcreate -L 10G -n data pve
  Logical volume "data" created

create file systems

root@tab:~# mke2fs -j -m 0 /dev/hda2
root@tab:~# mke2fs -j -m 0 /dev/pve/root
root@tab:~# mke2fs -j -m 0 /dev/pve/data
