If you are familiar with social media or research papers, you must know tagging already – You use keywords to label an entity, be it a blog post, an article, or something else, so that it can be easily searched out. So it’s a very useful feature in managing information.
In vSphere 4.0, VMware added tagging capabilities to the managed entities. According to the API reference of 4.1, it’s still an experimental feature and Read more...(413 words, 1 image, estimated 1:39 mins reading time)
After publishing the tech talk slides, I am happy to announce that the record is ready now. If you have missed the onsite or online session, or simply want to watch it again, please feel free to click here. Note that you will need Adobe Flash 10.1 or higher to view the recording.
Many thanks to my colleague Luke Kilpatrick (@lkilpatrick) for helping with online streaming and recording, and Matt Dhuyvetter for setting up the top quality audio feeds!
My colleague John Troyer (@jtroyer), who hosts VMware Communities Roundtable, has posted an interview with Alan Renouf (@alanrenouf) and me about our thoughts on VMware SDKs, APIs, and CLIs on May 18. During the interview, I answered questions about the open source vSphere Java APIs, the themes of my blogs (why it’s called doubecloud), what I am doing now at VMware, and of course our first community meetup event on the same day. If you have missed the session, you can listen to it now: , or here. Read more...(169 words, estimated 41 secs reading time)
Our first community meetup event on Wednesday night was a great success. It attracted about 200 developers/QAs and administrators globally either on site or online with live streaming. An EMC development team flied all the way from Irvine to join us; so did Huawei Symantec from Chengdu of China.
At the end of the meetup, we gave way 20 copies of these books: VMware VI and vSphere SDK by me, VMware vSphere 4.1 HA and DRS Technical deepdive (Volume 1) by Duncan Epping, VMware vSphere PowerCLI Reference: Automating vSphere Administration by Luc Dekens and Alan Renouf, andVMware ESX and ESXi in the Enterprise: Planning Deployment of Virtualization Servers (2nd Edition) by Edward Haletky; and many gadgets.
We know our attendees took their personal time mainly not Read more...(360 words, 2 images, estimated 1:26 mins reading time)
After preparing the event for almost two months, we are finally ready. If you join us onsite, here is direction to our venue. We have free food/drinks, and many books/gifts waiting for you, thanks to our sponsors and 12 volunteers.
If you join us online, we have a great news for you. Instead of WebEx, we will have a live broadcasting. Here is the URL: http://bit.ly/osvimeetup, courtesy of @lkilpatrick. You can enter as a Guest on 7PM (Pacific Time) for tech talks.
Here are the 8 tech talks we pulled together. A bit long but Read more...(1066 words, estimated 4:16 mins reading time)
Yesterday the VMware community noticed that the direct ESX download links were removed from vSphere download page. When I checked the download page, the ESX link is not with the bundles but at the end of the page in its own section.
To my own curiosity, I wonder what the adoption ratio of these two hypervisors is today. As an engineer, I don’t have sales data in front of me. Even I have, I am sure if I can share it here.
Days ago I introduced the new licensing APIs since vSphere 4 and a sample that prints license expiration dates. Here is yet another sample that replaces an old license with a new license.
You may be wondering why anyone would do this. This is in fact not a typical use case. You probably know that vSphere Client does not treat license keys like passwords which are not visually displayed as dots or asterisks. As a result, anyone who can access a vSphere Client can write down license keys and use them elsewhere.
Normally this is not an issue at all. What about Read more...(423 words, estimated 1:42 mins reading time)
In my previous blog, I introduced the new licensing APIs since vSphere 4. As promised, I will write samples showing how to use the APIs.
Here is the first sample (stay tuned to next one, coming soon). What it does is to check the licenses in vCenter server for their expiration dates, and print them out in the console. You can of course save them into other format, say an CSV file so that you can use Excel to further analyze it. To run the sample, you must change the IP address to the vCenter server, the username/password, as would with most VI Java API samples.
Note that a license could be an Read more...(290 words, estimated 1:10 mins reading time)
There has been a total change in vSphere licensing model since version 4. Before that, you need a special/dedicated licensing server which may be more flexible/powerful but also cause many troubles in production environment which made licensing related issues one of the top categories in tech support.
vSphere 4 has dramatically simplified the whole licensing model, and removed the licensing server. To find out how the new licensing model works, check out the VMware vSphere 4 Licensing Guide. It covers both the vSphere side and the portal with which you can easily manage your license keys: splitting/combining, etc. This article does not cover the portal part but related APIs only.
Management APIs reflect product features. If you check the latest API reference, you will find out Read more...(1111 words, 1 image, estimated 4:27 mins reading time)
If you want to read information about a virtual machine from the guest OS running on it, the vSphere Guest API is for you. It’s a C library coming with VMware Tools. Unlike the vSphere API which can be used anywhere, the vSphere Guest API is only available in the guest OS.
