Excitement is building around SDS, but unfortunately, so is the confusion.
As a developer, one drawback of using Google Web Toolkit (GWT) for the oVirt Administration Portal (aka webadmin) is that the GWT compile process takes an exceptionally long time. If you make a change in some code and rebuild the ovirt-engine project using make install-dev ...
, you'll be waiting several minutes to test your change. In practice, such a long delay in the usual code-compile-refresh-test cycle would be unbearable.
Luckily, we can use GWT Super Dev Mode ("SDM") to start up a quick refresh-capable instance of the application. With SDM running, you can make a change in GWT and test the refreshed change within seconds.
If you want to step through code and use the Chrome debugger, oVirt and SDM don't work well together for debugging due to the oVirt Administration Portal's code and source map size. Therefore, below we demonstrate how to disable source maps.
Open a terminal, build the engine normally, and start it.
``` make clean install-dev PREFIX=$HOME/ovirt-engine DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.cssResourceStyle=pretty -Dgwt.userAgent=safari" BUILD_UT=0 DEV_EXTRA_BUILD_FLAGS="-Dgwt.compiler.localWorkers=1"
…
$HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start
```
In a second terminal, run:
Chrome:
make gwt-debug DEV_BUILD_GWT_SUPER_DEV_MODE=1 DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=safari"
or
Firefox:
make gwt-debug DEV_BUILD_GWT_SUPER_DEV_MODE=1 DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8"
Wait about two minutes Continue reading
We’re watching them (watching you).
Plenty of reasons to not use it, basically.

After finishing up Mobility Field Day last week, I got a chance to reflect on a lot of the information that was shared with the delegates. Much of the work in wireless now is focused on analytics. Companies like Cape Networks and Nyansa are trying to provide a holistic look at every part of the network infrastructure to help professionals figure out why their might be issues occurring for users. And over and over again, the resound cry that I heard was “It’s Not The Wi-Fi”
Most of wireless is focused on the design of the physical layer. If you talk to any professional and ask them to show your their tool kit, they will likely pull out a whole array of mobile testing devices, USB network adapters, and diagramming software that would make AutoCAD jealous. All of these tools focus on the most important part of the equation for wireless professionals – the air. When the physical radio spectrum isn’t working users will complain about it. Wireless pros leap into action with their tools to figure out where the fault is. Either that, or they are very focused on providing the right design from Continue reading
Settlement-Free Peering Requirements. I explained the Peering , Types of Peering basics in one of the previous posts. When we talk about peering, we generally mean settlement-free peering. But what are the common requirements for companies to peer with each other ? Settlement-free peering is called as Internet Peering as well. So, companies setup […]

While the hyperscalers of the world are pushing the bandwidth envelope and are rolling out 100 Gb/sec gear in their Ethernet switch fabrics and looking ahead to the not-too-distant future when 200 Gb/sec and even 400 Gb/sec will be available, enterprise customers who make up the majority of switch revenues are still using much slower networks, usually 10 Gb/sec and sometimes even 1 Gb/sec, and 100 Gb/sec seems like a pretty big leap.
That is why Broadcom, which still has the lion’s share of switch ASIC sales in the datacenter, has revved its long-running Trident family of chips, which lead …
Making Mainstream Ethernet Switches More Malleable was written by Timothy Prickett Morgan at The Next Platform.
Useful commands for managing VMs and vSwitches from ESX console. If the command has been executed successfully there will be no output returned to screen (no output = success!!!).
Intel NUCs only come with 1 built in NIC so when using them as ESX hosts it is useful to add additional USB ethernet adaptors. Before these will be recognised by the ESX OS the drivers need to be installed using a VIB file.
