Xen Project 4.7 Planning Opens

With Xen 4.6 released in October, we are already one month into the new cycle. Which means it is time to start planning for the next release. You may remember that one of the goals of the 4.6 release planning was to create smoother developer experience and to release Xen 4.6 on time. Both goals were achieved, so it was time to think where to go from here.

GPFS Client Node cannot be added to the GPFS cluster

At the NSD Node, I issue the command
# mmaddnode -N node1
Thu Jul 23 13:40:12 SGT 2015: mmaddnode: Processing node node1
mmaddnode: Node node1 was not added to the cluster.
The node appears to already belong to a GPFS cluster.
mmaddnode: mmaddnode quitting. None of the specified nodes are valid.
mmaddnode: Command failed. Examine previous error messages to determine cause.

If we do a mmcluster, the node is not around in the cluster

Security vs Features

We’ve just released a rather interesting batch of Xen security advisories. This has given rise in some quarters to grumbling around Xen not taking security seriously.

I have a longstanding interest in computer security. Nowadays I am a member of the Xen Project Security Team (the team behind security@xenproject, which drafts the advisories and coordinates the response). But I’m going to put forward my personal opinions.
