Libvirt checks at configure time

  AC_PATH_PROG([PVCREATE], [pvcreate], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([VGCREATE], [vgcreate], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([LVCREATE], [lvcreate], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([PVREMOVE], [pvremove], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([VGREMOVE], [vgremove], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([LVREMOVE], [lvremove], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([LVCHANGE], [lvchange], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([VGCHANGE], [vgchange], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([VGSCAN], [vgscan], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([PVS], [pvs], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([VGS], [vgs], [], [$PATH:/sbin:/usr/sbin])
  AC_PATH_PROG([LVS], [lvs], [], [$PATH:/sbin:/usr/sbin])

So perhaps Arch didn't rebuild their libvirt package, after they moved
all the LVM tools.
