My Geek Finds

I just picked this up today – VMware Cookbook – A Real-World Guide to Effective VMware Use

Most of the book was written while vSphere was still in beta so the book covers ESX/ESXi 3.5 and Virtual Center 2.5.

I have only thumbed through it so far but it looks like there is a lot of good information. There are some pretty good tables with the configuration differences between 3.5 and 4 in Chapter 1. The command line reference in Chapter 5 should be useful to both versions, as well as the Security stuff in Chapter 6.

Looking forward to reading the book cover to cover.

Not sure why this is but Web Access to ESX 4 is disabled by default.

To enable it ssh to the service console and log in as root.

[root@vmware]# chkconfig –level 345 vmware-webAccess on

Verify it has been enabled for run level 3, 4, and 5

[root@vmware]# chkconfig –list vmware-webAccess
vmware-webAccess 0:off 1:off 2:off 3:on 4:on 5:on 6:off

Start the service

[root@vmware]# service vmware-webAccess start
Starting VMware Virtual Infrastructure Web Access:
VMware Virtual Infrastructure Web Access [ OK ]

You can now log in a root at https://vmwareESXhostname/ui/

Does anyone know why VMware disabled this by default?

VMware vSphere Evaluators Guide

Awesome resource for anyone looking into deploying or upgrading to vSphere 4.0

We upgraded our vCenter server on Tuesday AM and all is well so far. Our production ESX servers are still on 3.5 Update 4 and vCenter is managing them fine. We have tested the storage vmotion and converting vmdks from thick to thin – so far so good. The management interface is a little different but I like it. The new inventory views of Networking and Datastores are very handy.

We upgraded our test ESXi server this AM to ESXi 4.0 using the vSphere Host Update Utility. The upgrade went very well. The only real problem we ran into was with an older NIC that was not supported. No problems other than that.

Our test ESX server is a HP DL380 G4 with 2 3.6GHz Xeon CPUs (Single Core) and 4 GB RAM. This is managed as a stand alone server, it is not managed by vCenter.

If all goes well we will probably upgrade production ESX host this Sunday night.

Hope to have at least an overview of what I did at EMC World posted in the next day or so, just too busy right now.

These are very handy when trying to troubleshoot VM/vCenter/ESX issues. Just identify the path for the issue and read the KBs.

Many common tech support issues in VMware products can be solved using what we call Resolution Paths. Resolution Paths are collections of modular steps that can be used to solve tech support issues.

These can be very handy and can save you having to make that call into Tech Support. Click the links below. There’s one for each potential problem area.

Just doing a little reading on the possibilities of running Cisco Call Manager (Unified Communications), Unity, and CRS (UCCX) in a virtual environment.

Cisco actually supports running Unity as a virtual machine guest in ESX. The Desgin Guide is here http://www.cisco.com/en/US/docs/voice_ip_comm/unity/virtualization_design/guide/cuvirtualdg010.html

Cisco does not support Vmotion, HA, or iSCSI attached storage for a virtualized Unity box. They also do not support a physical to virtual conversion of a Unity server. Hopefully Cisco will support Vmotion and HA at some point.

I also found some interesting information on running an older Call Manager version (4.x) as a VM – http://www.blindhog.net/cisco-install-call-manager-4x-with-vmware/

Here is some info I found on UCCX – http://tannerezell.com/cisco/?p=85
