Hi, same to me . and the free space of storage is enough for uploading .
when I upload the file with size less than 4GB, I can see the progress 1% , 2% ... , when I upload the 4.2 GB ISO , there's no progress info on the bar , but only a status "importing" which can last for many days.
anyway , now i am used to import vm template to instead of ISO .
