To: [e-mail]

Hello,

Now i want to make an bootable iso image for aarch64,but when i installed
the livecd-tools ,it can't use like x86_64,it prints like below:
"Traceback (most recent call last):
  File "/usr/bin/livecd-creator", line 28, in <module>
    import imgcreate
  File "/usr/lib/python2.7/site-packages/imgcreate/__init__.py", line 19,
in <module>
    from imgcreate.live import *
  File "/usr/lib/python2.7/site-packages/imgcreate/live.py", line 1040, in
<module>
    raise CreatorError("Architecture not supported!")
imgcreate.errors.CreatorError: Architecture not supported! "
and i have a question : How to make the fedora21 DVD for aarch64 ??

Thanks very much

If you just want an F21 bootable *virtual* image for testing then you
can build one directly with virt-builder from any other Fedora >= 20
host [including from x86-64 hosts, but some less important
virt-builder options won't work]:

$ virt-builder --arch aarch64 fedora-21 --size 20G
[   2.0] Downloading: http://libguestfs.org/download/builder/fedora-21-aarch64.xz
[   3.0] Planning how to build this image
[   3.0] Uncompressing
[  13.0] Resizing (using virt-resize) to expand the disk to 20.0G
[  51.0] Opening the new disk
[  73.0] Setting a random seed
[  73.0] Setting passwords
virt-builder: Setting random password of root to B0gV73BwMCxLfnyu
[  74.0] Finishing off
                   Output file: fedora-21.img
                   Output size: 20.0G
                 Output format: raw
            Total usable space: 19.0G
                    Free space: 18.2G (95%)

Such an image can be imported into libvirt on your aarch64 host using
a `virt-install --import' command which is listed in the virt-builder
man page[1].  You can also boot it on x86-64 hosts under software
emulation using [2].

It may also be possible to boot this image on baremetal by writing it
to a USB stick: add the virt-builder `--output /dev/sdX' option.
However this depends on whether your aarch64 firmware can boot from
USB, which may or may not be possible.  I think the firmware on the
Mustangs can boot from USB DVDs but not USB keys, but I've not tried
either so I don't know for sure.

Virt-builder cannot create CDs/DVDs/ISOs.

That should be:

Add the virt-builder --output /dev/sdX option and *drop* the --size 20G
option, since virt-builder detects the size from the output device.
The final command line for USB sticks would be:

$ virt-builder --arch aarch64 fedora-21 --output /dev/sdX

Thanks very much.I will try this method.
 I have followed the mock instruction by Paul Whalen , and now I get a
DVD iso files, but there are some warning or errors in the process
like below:

preparing to build output tree and boot images
rebuilding initramfs images
rebuilding boot/initramfs-3.19.3-200.fc21.aarch64.img
No '/dev/log' or 'logger' included for syslog logging
Failed to read /proc/cmdline, ignoring: No such file or directory
cat: write error: Broken pipe
rebuilding boot/upgrade-3.19.3-200.fc21.aarch64.img
No '/dev/log' or 'logger' included for syslog logging
Failed to read /proc/cmdline, ignoring: No such file or directory
cat: write error: Broken pipe
populating output tree and building boot images
running aarch64.tmpl
INFO:program:Running...

maybe it's the mock configuration caused??

Those look fairly harmless.  It's probably caused by dracut running in
the chroot expecting to find /proc mounted.  If the final DVD works,
then you can probably ignore them.
