Hi,
The issue is that you are using the virt-install --disk option
incorrectly. If you look into man page of virt-install you can see some
examples. The options for each parameter needs to be separated by
comma. The command line that you are using is telling virt-install to
use 2 disks, one with the path and second one with only size provided.
If you want to have only a single disk for your VM you need to use it
like this:
virt-install \
[ ... ] \
--disk path=/Share2/KVMImages/arch01.qcow2,size=10 \
[ ... ]
