Override vSwitch failover order
In my VMware home lab, I want to use one NIC for the production data generated by my Virtual Machines and the other NIC exclusively for the Service Console. This setup also could work if you want to combine your management network with a VMotion Kernel Port Group. I created one vSwitch with two NICS and two Port Groups and then used the “Overriding Policies for a Port Group policy” to bind the Service Console to vmnic0 and the Virtual Machines to vmnic1. On top of that, I still have redundancy. If one in the NICS will fail, both the Service Console and the Virtual Machine Port Group will use one NIC exclusively. Load is balanced by selecting a different Active Adapter for each Port Group. Select an other active and standby adapter for both Port Groups. In a failover situation, standby adapters activate in the order specified below.
Override vSwitch failover order and select active and standby adapters for the Service Console and Virtual Machine Port Groups. In a failover situation, standby adaptors will become active.
Forcing shutdown of VMware VirtualCenter now
I encountered a little issue when restarting my Windows 2003 server hosting both VirtualCenter and the internal SQL 2005 Express database. SQL wasn’t fully started before VirtualCenter tried to logon and generated the following failure.
SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again.
Just e few events further Virtual Center was shutting down on me.
Forcing shutdown of VMware VirtualCenter now.
I know you can set a dependency on the VirtualCenter service so it would wait until SQL was fully running and till my great surprise, my old friend Andrew Kutz already has written an article about it.
You just need to add a value to the following registry key.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vpxd and edit the DependsOnService property (REG_SZ_MULTI) and add the MSSQL$SQLEXP_VIM value.
