For me creating the images does not take any noticeable time. Only when 
the installer formats the "disk" to ext3 (or others), it will take some 
time. Probably your syntax does not work. Try the syntax in my example, like

--disk path=/kvmail/mail.img,size=290 \

(making sure that the image does not exist beforehand).

You are probably reading some outdated howtos. No wonder, because where 
are the up-to-date howtos?? Red Hat Virtualization Guide is a nice book, 
but only an overview - it does not go into the gritty details.

I just got the double slash too on one installation try. I believe the 
double slash is an error of the error messaging. :-) If so, it only 
shows the level of "sophistication" of virt-install.

So it should. But that only "sanitizes" the error message, and 
erroneously (producing a double slash). :-)

I am just installing CentOS 4. I tried it first without a trailing slash 
in the path, and I got instantly "unable to get the image" or so. After 
that I could not get the image again, whatever I did. I had to restart 
the install from scratch, and then, after being sure to add the trailing 
slash, I got the image at once.

If this is problem in Anaconda or virt-install, I am not sure.

Ok, that could be the case.
