When creating a new hard drive on a Guest VM, there is an error:
disk image '/var/lib/vz/images/1110/vm-1110-disk-0.raw' already exists at /usr/share/perl5/PVE/API2/Qemu.pm line 1279. (500)

Here are the choices for the disk when creating it:

Bus Device: VirtO 7
Storage: local (23TB available)
Disk Size 64GB
Raw Disk Image (raw)
Cache: Write Through
Discard (checked)

There are 7 other disks on the VM with the same settings.

Full out put here:

could you run debsums -c pve-qemu-kvm libiscsi7 to verify non of the package-provided files on your system are corrupt? could you also post the output of the following commands
Code: 
apt show libiscsi7
ldd /usr/bin/qemu-img
qemu-img -V
 
Hi,

No output for the command-

Description: iSCSI client shared library
Libiscsi is a clientside library to implement the iSCSI protocol
that can be used to access resource of an iSCSI Target.
.
The library is fully async with regards to iscsi commands and scsi
tasks, but a sync layer is also provided for ease of use for simpler
applications.
.
This package contains the library itself.

what does which qemu-img say? anything non-standard at all about that system?
 
can you try the following command and attach the resulting file "ld_debug.txt"
LD_DEBUG=libs,symbols qemu-img -V 2> ld_debug.txt
