Version-Release number of selected component (if applicable): RHEV 5.6


How reproducible: Very reproducible, Roman Hodain  reproduced the issue with extra logging adding:

   #/bin/sh -x
   exec &>/root/pki.out

to /usr/share/ovirt-engine/bin/pki-pkcs12-extract.sh and reproducing the issue. The openssl complains about /dev/fd/1 which is not available during the installation:

/root/pki.out:
   openssl pkcs12 -in /etc/pki/ovirt-engine/keys/engine.p12 -passin pass:mypass -passout pass: -nocerts -out /dev/fd/1 -nodes
   Error opening output file /dev/fd/1
   /dev/fd/1: No such file or directory

To fix the issue:

As it turns out the device is missing during the installation. A workaround can be achieve by adding the following in the post script of the kickstart:

    mkdir /dev/fd
    ln -s /proc/self/fd/0 /dev/fd/0
    ln -s /proc/self/fd/1 /dev/fd/1

                || die "Cannot create key"

        return 0
