VMware VCP-DCV training and certification.

November 5, 2014 Leave a comment

Last week, I was in the course of VMware VCP-DCV. I decide to start again with my post updating.

To log and record my works, experience and the learning path, this is a very good way. I saw some one in China publish his own books based on the article him write during the daily works. Hope one day I can do that : D.

This week I was doing the Esxi 5.5 install. Before that I was using XenServer 6.2 on two desktops to learn my Citrix CCA certification. As I got that and I would like to get VCP certification soon, I need to phase out Xen and get back to Esxi again.

I used the tool ESXi-Customizer to add customized VIB file to Esxi iso and installed on two Desktop. I used command line installed VIB file to a running Esxi 5.5 in order to get more NIC.


The issue is I have DC on XenServers, it can’t boot up after I convert it to Esxi using VMware vCenter Converter Standalone. I’ll fix this soon.


And I saw some one said that it’s better to built new DC on Esxi and demoted the previous one. I’ll try this then.

Freenas bge0 error. watchdog timeout

August 6, 2013 2 comments

Just reference. This is from a article from Internet.

Currently I got a HP DL 120 in production with a HP NC107i PCIe Gigabit NIC (NetXtreme BCM5723) and FreeBSD 9.0-RELEASE #0 installed. At first those entries in /var/log/messages were ignored because everything was running smooth and the system seemed normal and stable:

bge0: watchdog timeout -- resetting
bge0: link state changed to DOWN
bge0: link state changed to UP

With increasing network load there were a few unusual latency peaks and finally the NIC shut down or the system was frozen (w/out any messages of course). I couldn’t figure that one out, it is a remote box w/out KVM access. After some research I found that In order to get rid of those messages you need to disable bge0 ASF driver features by adding


to your /boot/loader.conf – and yes, you really need to reboot your machine since sysctl hw.bge.allow_asf=”0″ will fail with “sysctl: oid ‘hw.bge.allow_asf’ is read only”. Those messages are gone now and the system seems stable as it should be.

Have fun!

p.s.: edit 25th of June 2012: The system is stable, issue solved.
