Wherever your disk image is located (/home/kvmimages) QEMU should be
able to access it (executable bit for 'others'). For instance, I have
these permissions for my home directory where I store VM images:
$ ls -lash / | grep home
4.0K drwxr-xr-x. 7 root root 4.0K Aug 7 2013 home
Permissions on the specific directory where I store VM images
(/home/kashyap/vmimages):
$ ls -lash /home/kashyap/ | grep vmimages
4.0K drwxrwxr-x. 2 kashyap kashyap 4.0K Jun 14 21:50 vmimages

If I'm parsing you correctly, you've SSHed into the remote machine and
running virt-install. Like I said, if QEMU can access your home
directory (as I noted above), where you're storing disk images, you
shouldn't have any issues.
