Hey,

Is it safe to install libguestfs-tools? It installs a lot of stuff and I don't know if/how it interferes with current PVE services.

hi,

it's not compatible with PVE.

why do you need it?
 
hi,

it's not compatible with PVE.

why do you need it?
I would like to generate some cloud ready images, and for that I need virt-sysprep and virt-sparsify. I don't need any kind of compatibility with PVE, I just don't want to break it if I install the aftermentioned tools.
 
you can install it, it shouldn't break your install.

i'd install it with apt install --no-install-recommends --no-install-suggests libguestfs-tools.

just be aware that you can't manage proxmox guests with libvirt.
 
Yes it's safe to install it. It may or may not work inside a VM if nested KVM is broken. If it fails, try setting:

export LIBGUESTFS_BACKEND_SETTINGS=force_tcg

and if that doesn't work run `libguestfs-test-tool`.
 
FWIW, the suggestion from @oguz was needed for my purposes (proxmox-ve6.3-2) - otherwise you'll run into this:

Code:
The following packages will be REMOVED:
  proxmox-ve pve-firmware pve-kernel-5.4

I have strange behavior on proxmox 7.1. Without libguestfs-tools installed mounted images are not available inside LXC.
Just installing this tool fix the problem - but I am not even using libguestfs-tools directly.

What I have:
proxmox 7.1 host with LXC alpine with bind-mount (mp0: /media/storage/,mp=/media/nas,mountoptions=noatime)
vhd image file located at host in /media/storage/image.vhd

What I need:
mount vhd image on host and make it content available inside LXC alipne

What I am doing:
modprobe nbd max_part=8
qemu-nbd --connect=/dev/nbd0 /media/storage/image.vhd
fdisk /dev/nbd0 -l
mount /dev/nbd0p1 /media/storage/vhd

It is only working if libguestfs installed and only if I execute this commands AFTER LXC started...
Is it safe to keep using this approach or it work just by a mistake?

Without libguestfs I am getting access error in LXC (vhd contain NTFS file system) and cant fix it even by chmod (FS in readonly mode).
