VMware vSphere: Safely remove network controller

Tue, 23 Feb 2010 18:24:01 +0000

Well, it’s another day another fight. As we started migrating our VM’s from the old VMware ESX farms to the new environment, and upgraded the hardware suddenly the network devices were hot-plug-able, thus they did turn up in the “Safely Remove” dialog.

I myself don’t have any trouble with that. The trouble I do have is the people working with those VM’s and their possibly hazardous “uuuh, what’s this ? I don’t need this! <click-click, network-device unplugged>”

ESX: Query CDP information from the command line

Thu, 29 Oct 2009 17:20:46 +0000

I’m just tracing some troubles I’m having with a backup server and two (independent) network adapter ports (as in two ports on two different dual-port nics). If I enable the port and set it to auto configuration, it’ll get 100MBit/Half-Duplex, but the Portgroup becomes unavailable.

In order to get the connection back, I need to logon on the console (thank god even the backup server got an iLO2), and manually (as in esxcfg-nics -s 1000 -d full vmnic1) configure the adapter to 1GBit/s and full-duplex.

VMware vSphere and templates

Fri, 31 Jul 2009 13:51:01 +0000

I just converted one of my (old) templates, as I wanted to refresh the updates and the virus scanner. After converting, I was asked about the UUID (no clue why), and expected to be done with it. But after looking at the console, I got the following, completely cryptic message:

Unable to connect to MKS

After digging a bit deeper (that is looking at the vmware.log of the virtual machine, since the message of the GUI is real cryptic), I’m a bit wiser:

Updating a Linux VM from Virtual Infrastructure to vSphere

Wed, 08 Jul 2009 13:51:50 +0000

Well, if you’re gonna update a SLES10 (or even a SLES11) VM, you created with Virtual Infrastructure, you’re gonna run into a snag (like I do). Grub (or rather the kernel itself) is gonna barf.

Now, I searched for a while and didn’t find anything specific on the net, so I’m gonna write it down. Up till 3.5U4 the maximal resolution you’d be able to enter within a virtual machine was vga=0x32d (at least for my 19" TFT’s at work). But now, after the upgrade to vSphere that isn’t working anymore.
