Subject: [PATCH] v2v: -i ova: Fix parsing if OVA directory name has a trailing
0602f3
 "/"
0602f3
0602f3
If you use an OVA directory with a trailing "/" in the name, virt-v2v
0602f3
would fail with:
0602f3
0602f3
virt-v2v: error: internal error: assertion failed at parse_ova.ml, line 273, char 15
0602f3
0602f3
The fix for this is to knock off the trailing "/" if present.
