Why not? That's, in my case, basically saying "you should not be running
trim on a drive exported via iscsi" Perhaps I shouldn't be but I'd like
to understand why. Enabling thin_provisioning and fstrim works and gets
mapped to the underlying layers all the way down to the SSD.

My underlying VG is less than 50% occupied, so I can trim the free space
by creating a LV and then removing it again (I have issue_discards set)

FWIW, I did issue fstrim in the VMs with no visible issues at all.
Perhaps I got lucky?

I don't see VM or virtual machine anywhere on that page.
