Xen Project Security Policy Improvements: Get Involved

The recent XSA-108 vulnerability resulted in a lot of media coverage, which ended up stress-testing some of our policy and security related processes. During the embargo period of XSA-108, the Xen Project Security Team was faced with some difficult questions of policy interpretation, as well as practical issues related to pre-disclosure list membership applications.

The Windows PV Drivers Sub-Project

Back in 2013 Citrix made XenServer fully open source. As part of that work the previously closed Windows drivers for paravirtual devices were opened up and made available to the community on . These drivers were still very much tied to XenServer though because of assumptions that were made about the platform and reliance on certain patches carried in the XenServer patch queues.

XSA-108: Not the vulnerability you’re looking for

There has an unusual amount of media attention to XSA-108 during the embargo period (which ended Wednesday) — far more than any of the previous security issues the Xen Project has reported. It began when a blogger complained that Amazon was telling customers it would be rebooting VMs in certain regions before a specific date. Other media outlets picked it up and noticed that the date happened to coincide with the release of XSA-108, and conjectured that the reboots had something to do with that.

XSA-108: Additional Information from the Xen Project

The Xen Project Security Team today disclosed details of the Xen Security Advisory 108 / CVE-2014-7188 (Improper MSR range used for x2APIC emulation). The Xen Project does not normally comment on specific vulnerabilities other than issuing security advisories. However, given wide interest in this case, we believe it is helpful to provide more context.

Welcome to the Newly Revised (and Revived) Xen Project Blog

After several days offline, the Xen Project blog has returned!

Our blog had been subjected to malicious activities, so we had to take it down and remedy the situation. We’re back now, and although there are a few minor issues to address, we are ready to move forward.

RDO Setup Two Real Node (Controller+Compute) IceHouse Neutron ML2&OVS&VXLAN Cluster on CentOS 7

As of 07/28/2014 Bug https://ask.openstack.org/en/question/35705/attempt-of-rdo-aio-install-icehouse-on-centos-7/ is still pending and workaround suggested above should be applied during two node RDO packstack installation.
Successful implementation of Neutron ML2&&OVS&&VXLAN multi node setup requires correct version of plugin.ini -> /etc/neutron/plugins/ml2/ml2_conf.ini which appears to be generated with errors by packstack.
