VMware ESX 3.5, Patch ESX350-200904401-BG: Updates vmkernel vmx hostd etc

VMware recently released a patch, ESX350-200904401-BG which resolves a number of issues, which can be found in KB1010126.

The biggest fix that has affected me lately is, “Fixes an issue where an unsuccessful online consolidation might cause a virtual machine to fail and become unusable because of a CID mismatch.”

I recently ran into some problems with some virtual machines that have high I/O failing during the commit of a snapshot, I discussed this in an earlier post which can be found here.

I’d highly recommend anyone running ESX 3.5 to apply this update as it resolves a lot of known issues that can affect VM performance and stability.  Always remember to follow proper patching procedures, thoroughly test the patch install and verify before placing production Virtual Machines back on the host.

    I too recently had problems with this known bug. I was experiencing latent io errors when trying to convert a physical server into my ESX host. I could see the errors when you went to /var/log and did a less vmkernal or tail -f vmkernal and I could see:

    cpu2:1077)scsi(0): Waiting for LIP to complete…

    I patched all my hosts using Update Manager and I will have to see if this problem still exists.
