aarch64 / Raspberry Pi3
by Sandro Bonazzola 28 Oct '16

28 Oct '16

Hi, some time ago we've been asked to provide aarch64 build of qemu-kvm-ev for CentOS Cloud SIG consumption. We did it, and while at it we also built oVirt 4.0 VDSM dependencies for aarch64 in CentOS Virt SIG. Testing repositories have been created and are now publicly available: [centos-qemu-ev-test] name=CentOS-$releasever - QEMU EV Testing baseurl= http://buildlogs.centos.org/centos/$releasever/virt/$basearch/kvm-common/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Virtualization [centos-ovirt40-test] name=CentOS-$releasever - oVirt 4.0 Testing baseurl= http://buildlogs.centos.org/centos/$releasever/virt/$basearch/ovirt-4.0/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Virtualization We don't officially support aarch64 and this is highly experimental so expect bugs. But if you've a Raspberry Pi 3 and you decide to give VDSM a run, please share your feedback. Thanks, -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

by Pasi Kärkkäinen 26 Oct '16

Hello, I think we should build and release a new 3.18 kernel for the VirtSIG / Xen users.. It seems upstream 3.18.y tree has a release with the Dirty Cow security fix included, 3.18.44: https://kernel.googlesource.com/pub/scm/linux/kernel/git/sashal/linux-stabl… (also includes a Xen SMAP/PVOPS fix). Thanks, -- Pasi

Xen4CentOS kernel-debuginfo
by Sarah Newman 23 Oct '16

23 Oct '16

I think this may have been asked before, but what would it take to get debuginfo packages built for the Xen4CentOS kernels? If it's just a patch for kernel.spec file that nobody has gotten around to, what is the best starting place for making that patch? Thanks, Sarah

by George Dunlap 04 Oct '16

04 Oct '16

Xen 4.6.3-3 packages, with XSA-190, are currently making their way through the build system. The vulnerability is an intra-guest information leak (i.e., between different processes in the same VM). More information here: https://xenbits.xen.org/xsa/advisory-190.html -George

Hi, I just tried to setup ovirt-websocket-proxy. the package name in the upstream repo is e.g.: http://resources.ovirt.org/pub/ovirt-3.6/rpm/el7/noarch/ovirt-engine-websoc… I have the following repos enabled: yum repolist enabled Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.imt-systems.com * epel: mirror.imt-systems.com * extras: repo.de.bigstepcloud.com * updates: repo.de.bigstepcloud.com repo id repo name status base/7/x86_64 CentOS-7 - Base 9.007 centos-gluster37/7/x86_64 CentOS-7 - Gluster 3.7 139 centos-ovirt36/7/x86_64 CentOS-7 - oVirt 3.6 499 centos-qemu-ev/7/x86_64 CentOS-7 - QEMU EV 52 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 10.626 extras/7/x86_64 CentOS-7 - Extras 390 updates/7/x86_64 CentOS-7 - Updates 2.504 repolist: 23.217 shouldn't this suffice to install the websocket proxy? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

Fwd: Centos 6 AMI does not support c4-8xlarge
by John Peacock 22 Sep '16

22 Sep '16

One of the things suboptimal with Marketplace images is that the author can limit which instance types are allowed with the AMI and there is no way to override that. We are using Centos 6.8 for our deployments, but we need to move to the c4.8xlarge type, but that is not a permitted option for the "CentOS 6 (x86_64) - with Updates HVM" AMI. Is there any way we could get that image refreshed to support the largest image type? We really need the 10G networking for our application. Thanks in advance John -- JOHN PEACOCK senior software build and release engineer tel 877-887-3031 mobile 240-429-9334 email john.peacock(a)sparkpost.com

by C. L. Martinez 16 Sep '16

16 Sep '16

Hi all, I am trying to configure wlan0 interface to use it with kvm guests. I know that I need to use ebtables statements due to it is not possible to link wlan0 interface with a bridge. I have followed Debian's tutorial: https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_N… without luck. Someone have tried?? I am using CentOS 7 fully patched. Thanks.

You are right Alex. My processor doesn't support VT-d according to Intel. Many thanks for your help. -- Greetings, C. L. Martinez
