Per processor licenses for your application
Some vendors license their application per processor, also in a virtualized environment. So if your VM has 4 vCPU’s your vendor will want you to buy a 4 processor license for the application. But you can avoid this by telling the VM that it has cores instead of processors. In others words, instead of having [...]
After restart Virtual Center Server does not start automatically
In my case the SQL server and the Virtual Center server are on the same server. So I need to make the Virtual Center Server service dependent of the SQL server. To make this happen type the following in a DOS box. sc config vpxd depend= MSSQLSERVER Bookmark on Delicious Digg this post Recommend on [...]
iSCSI and VMWare Tips
I found a great article named A “Multivendor Post” to help our mutual iSCSI customers using VMware You really should read it if your using a SAN in combination with ESX 3.5 http://virtualgeek.typepad.com/virtual_geek/2009/01/a-multivendor-post-to-help-our-mutual-iscsi-customers-using-vmware.html Bookmark on Delicious Digg this post Recommend on Facebook Share on Linkedin share via Reddit Share with Stumblers Share on technorati Tweet [...]
Creating a quiesced snapshot failed because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine
This issue may occur due to incorrect snapshot configuration files. To fix the files: Connect to the ESX host or VirtualCenter through VMware Infrastructure Client. Select the virtual machine. Browse the datastores used by the virtual machine. Find and rename the files with the following extensions: *.vmsn *.vmsd Retry the snapshot or backup operation. If the operations [...]
Disk.UseLunReset and/or Disk.UseDeviceReset
A setting often overlooked is Disk.UseLunReset and/or Disk.UseDeviceReset. ESX defaults to Disk.UseLunReset=1 and Disk.UseDeviceReset=1. This means that when a SCSI bus is reset all SCSI reservations are cleared, not for a specific LUN but for the complete device. This is useful when one uses local storage, but within a VMware environment most companies utilize a [...]
Massive TCP Retransmits with ESX 3.5 U5, HP ProCurve 3500yl and Equallogic SAN – UPDATED
I’m using serveral ESX 3.5 U5 connected to 2 HP ProCurve 3500yl. When I monitor my Equallogic SAN with SAN Headquarters 2.0 there are a lot of TCP Retransmits. Sometimes more than 3%. After some troubleshooting I discovered the TCP Retransmits are caused by the ESX Nic Teaming connected to the HP ProCurve switches. Every [...]
What Files Make Up a Virtual Machine?
You may never need to know the file names or locations for your virtual machine files. Virtual machine file management is performed by VMware Workstation. If the behind the scenes file structure is not interesting to you, skip this section. A virtual machine typically is stored on the host computer in a set of files, [...]
VMWare ESX Server error: An invalid snapshot configuration was detected
While trying to create a snapshot on a host I received an error: An invalid snapshot configuration error occurred. Tech support was good and walked me through the resolution: # vmware-cmd -l [gets a listing of hosts and filesystem paths and combine the host that you are getting the error on with the vmware-cmd command: [...]
VMware Health Check Report v0.9.4
This script generates a health check report of all attributes pertaining to a single ESX/ESXi 3.x+ host or VMware vCenter and its managed entities (i.e. clusters and individual ESX/ESXi 3.x+ hosts). The generated report is based off of some earlier Powershell script work created by Ivo Beerens/Duncan Eppping. I was primarily motivated on this project [...]
