Today I experienced the error shown in the title of this post while opening the VM console of some VMs. This short post will help you solve this issue on short and long term.
Today I stumbled upon an issue where I couldn’t power on a particular VM without triggering a PSOD (Exception 14) on the ESXi host the machine was registered on. This article describes the reason for the PSOD and how I solved it using PowerCLI.
Alot has been going on in my head about how I should transform my homelab from a simple physical box with just plain vSphere 5.5 on it and memory consuming applications like Microsoft Exchange and Lync to a nested ESXi environment where I can test new VMware features and technologies apposed to the Microsoft technologies I have seen for many years now.
Last weekend VMware announced that vSphere 5.5 was available for download and I guess everyone hurried themselves to the download section of the VMware website including me! 🙂
I didn’t have time to actually use the binaries until last tuesday and thought of myself it would be cool to add something extra to my blog; video recordings! So, here it is, my first video recording during my upgrade from vSphere 5.1 to 5.5.
While beginning to write, the session didn’t start yet. This is the first time I’m going to see Cormac Hogan live. I heard good things about him in a technical way. Next to him on stage will be Kyle Gleed, both Cormac and Kyle are from the Cloud Infrastructure Technical Marketing team.
This session will be about the new vSphere 5.5 features, including new features for storage.
This morning the second keynote was kicked off by Carl Eschenbach, President and Chief Operating Officer of VMware. He pretty much recapped the announcements made yesterday:
- vSphere 5.5
- vCloud Suite 5.5
- Cloud Foundry
- vCloud Automation Center
See my blog post about the General Session on monday below in the related articles section.
Today we finally heard how many attendees were here in San Francisco to be at the VMworld event: twenty-thousand-five-hundred. Holy shit!
Carl gave the word to Kit Colbert and Joe Baguley for the more technical details.
Next to the announcements, I got to know more about NSX now so I can tell my colleagues more about the technology. NSX makes it possible to bridge your NSX networks (VXLAN networks?) to the portgroups you created on the physical network and make life between virtual and physical networks a reality.
With this possible, NSX will provide switches, routers, firewalls and load balancers on your hypervisor and will be attached to your VMs and/or vApps. No more central network devices, just a bunch of features attached to your VM. Deployed when your VM gets deployed, removed when your VM gets removed. Automation eh? =)
NSX will prevent so called ‘hairpinning’ which means that VM traffic from one VLAN to another, on the same host, will flow thru the physical switches behind your ESXi hosts. NSX will happily route the traffic inside the hypervisor, speeding up traffic and decrease load on your physical network.
The demos about vCloud Automation Center were also very cool. The way customers and managers can request applications by using a user-friendly interface is something I want to build myself! Next, integrating vCenter Operations Management Suite with vCAC provides you and your customer with the latest status of their applications. Even more; when problems arise and vCOPS is able to fix it by adding capacity (in the form of auto-scaling, a new feature in vCAC enabling automatic enroll of VMs to your existing application cluster) or moving your vApp to a different storage tier, for example. These features an be enabled and disabled per user/customer and per VM.
I made some photos during the session to give a better impression of the topics and the speakers.
In september I will be giving a presentation together with my colleague Eelco de Boer (See related articles below) about this VMworlds highlights. I will most certainly show a demo of vCAC with vCOPS integration; very very cool!
