Small announcement: virt-builder CentOS 7.2 aarch64 image
by Richard W.M. Jones 14 Jul '16

14 Jul '16

You can now do: virt-builder centos-7.2 --arch aarch64 to get a CentOS 7.2 aarch64 image. The --arch parameter is not required if your host is aarch64, since it defaults to finding the same guest arch as host arch. Some other things you might try (these work as non-root too): virt-builder centos-7.2 \ --arch aarch64 \ --size 20G \ --hostname myguest --timezone Europe/London \ --root-password password:123456 \ --update --selinux-relabel virt-install --import --name myguest --ram 2048 \ --disk path=centos-7.2.img,format=raw --os-variant centos7.0 Note there is an updated virt-builder package available which is similar to what RHEL and CentOS will have in 7.3: https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/ Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.

Hello Hans, I am looking for bit of advice on how to handle these errors I see in the dmesg print , it starts here : [ 0.077227] pinctrl core: initialized pinctrl subsystem [ 0.079533] NET: Registered protocol family 16 [ 0.080837] DMA: preallocated 256 KiB pool for atomic coherent allocations [ 0.094301] No ATAGs?

Is there something that I am missing out in config , or a patch somewhere in the dts ? Any information welcomed . Best Regards Milorad

RPi 3, CentOS 7 install problem
by Steve Berg 12 Jul '16

12 Jul '16

Trying to get CentOS-Userland-7-armv7hl-Minimal-1603-RaspberryPi3.img installed to a SanDisk 64G SD card for a Raspberry Pi3. The dd goes well, the Pi will boot with no problems. I run "touch /.rootfs-repartition" and then a reboot. It seems to do the repartition but I get a kernel panic at the next reboot. On the console I see: ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,3) Any tips on how to get the SD card repartitioned to use the whole space after install? -- //- Fixer of that which is broke -// //- Home = sberg(a)mississippi.com -// //- Sinners can repent, but stupid is forever. -//

TFTP issue with PXE loaded grubaa64.efi
by Sakar Arora 12 Jul '16

12 Jul '16

Hi Jim, While testing CentOS 7 installation on LS2080a RDB, only on one of setups, we found this strange issue, where grub wasn't able to TFTP the boot images from TFTP server. We use grubaa64.efi provided on CentOS website<http://mirror.centos.org/altarch/7/os/aarch64/EFI/BOOT/>. >From the tftp server logs we found that the tftp transaction would always stop with a 'timeout' error. A quick search got me this bug<https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1508893> logged in Ubuntu bug tracking system. There was a mention of a patch, which is supposed to fix this issue. So, I went ahead and created a grub image with the latest upstream grub source code (git.savannah.gnu.org/grub.git) Using this grub image, fixed the issue with TFTP transfers. But, there's different kind of issue with this new grub image. It doesn't seem to be fully compatible with UEFI PXE boot protocol. When loading grub via UEFI PXE boot, the tftp server address does not get set in the grub environment variables, as was the case with grubaa64.efi from CentOS that we use. Can you share you views on this? Thanks, Sakar

next steps for altarch with ceph and openstack
by Jim Perrin 08 Jul '16

08 Jul '16

With the work that Marcin has done for openstack on aarch64, as well as the ceph builds, we need to begin working a plan for publishing these builds to a mirror. I'd like to identify the steps needed, and the ownership for those steps. Thomas please correct/update these as needed 1. new tag in cbs for aarch64 build, with modified dist for mitaka. Will ceph need this as well? 2. If we wish to re-use the centos-release-openstack-mitaka noarch, dependencies of centos-release-ceph-hammer, centos-release-qemu-ev, centos-release-storage-common, and centos-release-virt-common need to be addressed. Alternately we could create a centos-release-openstack-mitaka-experimental for now if it can work stand-alone. 3. Mirror locations on buildlogs and mirrors need to be created and tested. Possible adjustments to existing -release files due to the /altarch/ vs centos path differences. 4. Package signing. This should already work with existing infra, but need to test and validate. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

Hi all, I got success in building my centos-7-freescale sololite board image via build root factory. It got loaded successfully on my dev board. However, my wifi and bluetooth chips are not up still because i need to get uim and hostapd packages for armv7hl for testing my bluetooth and wifi chip driver. Is there any handy repo for getting uim and hostapd.? Regards Sudhanshu Bhutani
