Hi!

You should NEVER use a Virtual Machine from a person you do not really
know. You could never know how it is configured and if there are security
problems. We recently had a security incident in the Grid where someone
ran a virtual machine just for testing which he got from someone else.
Unfortunately the machine only had a really weak password and was used to
break into the local network...

Better use a kickstart or preseed file and create your own machine. To
create a kickstart file, you can use system-config-kickstart or adapt the
following kickstart to your needs. The password can be created with
openssl passwd -1 -salt "NaCl" "don't use this"
