We are pleased to announce the second public beta release of CentOS
Linux 7 for the AArch64 platform.

This release contains fixes and code updates provided in the RHELSA
source code recently published to git.centos.org as well as rolling
previous updates into the installer.

We intend to have a 'Gold' release very soon unless a blocker bugs are
reported, so please test this release.

Improvements since the initial Beta

The 4.1rc kernel has been removed in favor of the 3.19 kernel as it
contains some additional functionality by default. The 4.x kernel will
be available later as a -plus kernel.

Installation/Everything ISO is now available. We're currently offering
an Everything ISO that can be used for usb based installation if
desired. This iso is currently too large for standard DVD media, and so
is best used via usb media.

Many updated packages, including core packages likebzip2, dbus, grub2,
libaio, and more.

The full (unsigned) install tree is available at

Everything-ISO is available at

Installation guides and documentation will be provided via the CentOS
wiki, at http://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64

Update procedures for existing installations
Because the kernel version has been rolled back from 4.x to 3.19, you
will need to take some additional steps to update.

1. yum -y update
2. yum distro-sync # This will roll back the installed kernel packages
3. yum remove kernel-core kernel-modules # cleans up kernel leftovers.
4. reboot to new kernel


The AArch64 effort is meant to be a community effort as part of the
AltArch SIG (http://wiki.centos.org/SpecialInterestGroup/AltArch), and
we welcome enthusiasts and vendors to contribute patches, fixes,
documentation, etc. In the AArch64 Extras repository, we have provided
the mock package and dependencies so that community members can more
easily contribute, as well as testing their own builds locally. Please
submit patches, fixes, etc to the Arm-Dev list
(http://lists.centos.org/mailman/listinfo/arm-dev) for discussion and

We encourage vendors to come and join this effort, we have a loose
organization focused on the alternative architectures build process and
welcome interaction at the group level. Please get in touch with me
(jperrin at centos.org)  or K Singh ( kbsingh at centos.org ) to find out more

The wider CentOS Ecosystem is also welcome to engage with us, both at
the project and code level. If you are working with a project that
interfaces, manages or develops on top of CentOS, specially in the
virtualization, cloud, container and infrastructure management areas -
we would love to have you guys get involved. While we don't have a lot
of resources, we are working with a few vendors to build up a community
resource pool that we would encourage other projects to share their
development, testing and delivery around CentOS Linux for aarch64.
