vRA 7 / vRO 7 REST error (java.security.cert.CertificateException)

Whilst I was with a customer recently, I hit an SSL related issue whilst trying to put together a vRO workflow to orchestrate the creation of a load-balancer configuration on a Citrix Netscaler VPX. Adding the REST host(s) to vRO was accomplished without any issue, but when I came to use them my workflow failed with the following error:

As this vRO instance was running on a vRA appliance, my first port of call was starting the vRO Control Center service and make sure that the REST host certificates had indeed been imported in to vRO and were trusted. They were. Looking at the certificates themselves (as I had blindly accepted them up until that point) I noticed that they were self-signed and the cause of the error became clearer. Some software solutions generate fairly weak SSL certificates by default to […]

Changing vRA ExternalWfStubs Timeouts

I saw a question on Twitter this morning that I thought warranted a quick post: The default timeout for the various workflow stubs is 30 minutes, but they can be changed. As always, take backup copies and be careful! The six stubs that can be changed are: Expired RegisterMachine Disposing UnprovisionMachine BuildingMachine MachineProvisioned The timeout settings for External Workflow stubs are configured on the Windows server (vRA 6.x) that hosts the Manager role. The file and path required (assuming a default installation) is:

Using your favourite text editor, simply adjust the timeout value for each workflow. Most people tend to require a longer timeout for “MachineProvisioned”, often because they require longer running post-provisioning tasks to complete before handing a Virtual Machine over to the requester. Save the file and make sure that the same changes are made on the […]

Thank you Xtravirt…

It was with some sadness that I left the Xtravirt offices in Surrey for the last time recently. Due to the nature of my work I’ve rarely been there, but it always felt like home because of the people. If, for some reason, you’re not familiar with Xtravirt, they’re a leading virtualisation and cloud consultancy whose ambition and capabilities far exceed their size. They’ve got some great consultants, many of whom I’ve known from before they were at Xtravirt, great management and the highest ratio of vExperts per employee in the world (although that might have taken a hit). All good things (including the last 18 months of automation and orchestration work on two large-scale cloud projects) must come to an end however, so I wanted to take this opportunity to thank everyone at Xtravirt for the great times and […]

VMworld 2014 – Day 1

Tuesday in Barcelona is when things really get going. First up on everyone’s schedule is the VMworld keynote. This is one of times when attendees get to hear from Pat Gelsinger (VMware’s CEO) and a number of other presenters and get an overview of the direction in which VMware are going. It’s also when the major product announcements are officially made. Historically, VMworld Europe is usually the time when management product updates are announced (with some of the more infrastructure based updates happening at the US conference). It’s been slightly different this year I suppose since there was no major update to the core vSphere platform, but there was EVO:RAIL. During the keynote, announcements were made about: vRealize Automation 6.2 (formerly vCloud Automation Center) vRealize Operations 6.0 (formerly vCenter Operations Management Suite) vRealize CodeStream (coming soon – looks good!) Another […]
