Sorry, it must have GPT table so try:
sgdisk -p <your disk path>
Also:
vgs

This result in a empty partition table...
It sounds like I lost all partitions inside the guest

Ok guys...
All those steps I already perform...
I can shrink fs+partition+lvm inside the guest... Everything is ok!
But, when I perform this:
qemu-img resize vm.raw -3100G
the guest crash!
The raw image, on Proxmox fs has 3,9 TB...
Inside the guest, I have this:
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_bancosiscobra-lv_root
50G 4,7G 43G 11% /
tmpfs 939M 0 939M 0% /dev/shm
/dev/sda2 485M 67M 393M 15% /boot
/dev/mapper/vg_bancosiscobra-lv_home
640G 540G 68G 89% /home
With the qemu-img resize command showing above, I managed to
shrink raw image to 800GB, more than sufficient to boot the
machine...
But no way! I get error inside the guest...
My next shot will be this tutorial:

First try to shrink fs+partition+lvm inside guest vm with
gparted as Lindsay suggested.
Reboot the VM to check if resize completed successfully.
Check actual fs+partition+lvm sizes inside VM and verify
their total size.
Shutdown VM and try to resize raw disk so that the total size
is bigger at least some MB than the actual size.
For example if actual size is 1Tb resize it to 1.2-1.3 Tb
just to be safe.
Try booting the VM again.

So, inside the VM I managed to reduce the LVM and the
Filesystem...
But, when I try to use qemu-img resize, perhaps I mistake
something, because the crash down in kernel panic, 'cause
not found and partitions, even the LVM!
Are you sure that gparted live iso is safe???
Thanks

Use the GPartEd Live ISO
(http://gparted.org/download.php) to resize the LVM
*and* the partiton, then qemu-img to shrink it.

Hi guys
I was able to reduce LVM and root/home partition
inside a certain VM, runnning on Proxmox.
The VM has raw image.
This image was 4 TB of size..
But, when I try using command:
qemu-img resize vm.raw -XXXXG
The VM get crash! No partition remain....
So I thought use virt-resize to make this
operation....
I can use perhaps, other host, with virt-manager
and other virt tools installed, shrink the raw
image with virt-resize and get use the resulting
image to new VM on Proxmox...
Or, maybe you guys, has another solution...??
Thanks
