VMotion was failing at 78% with error message "A general system error occurred: Failed waiting for data. Error bad0007."
This was brand new cluster and everything is standard as per other cluster like ESX version ,host physical config etc…
I tried following:
V-motion was failing for all VM's within a cluster at 78%
- Tried to vmotion other vms within this cluster
- All of the Vm's failed at 78%
- Implemented KB 1003577 by installing Update manager
- Creating a baseline and updated 2 of the esx hosts involved in this and now both of the ESX Servers are now compliant with the latest versions of patches.
- Created a new cluster called "test Cluster" added two ESX host to this cluster
- Cold migrated over a VM and tried a Vmotion. It was still failing at same stage (78%)
- Checked/changed the Following variables according to KB 1003577
Migrate.PageInTimeoutResetOnProgress: Set the value to 1.
Migrate.PageInProgress: Set the value to 30, if you get an error after configuring the
Migrate.PageInTimeoutResetOnProgress variable.
Toggle the Migrate.enabled setting from 1 to 0, click OK, then flip the value back to 1, click OK.
These variables are both identical to what was recommended in the KB
Tried a V-motion this failed at 78%
- Tried Vmotion Servers on different Datastores this failed too.
- Swopped the Vmotion network to eliminate a problem with the type of card been used and this did not make a difference. It still fail at 78%
- Reduced the amount of ram that was been used in the VM this was set to 4GB to 2GB this still keep failing
- Installed Vmware Tools to this VM.
I created brand new test VM and it works fine. So it looks like there are something fishy about the VM itself. So we started to look at the log and found following
Checked the contents of the Vmware log for the VM been v-motioned an error similar to the following appeared
The vmware.log for the Virtual Machine (VM) being migrated has entries similar to:

When the amount of Video ram was commented out the following error appeared with the Log file for the VM
---------------------------------------------------------------------------------------------------------------------------------------
Aug 18 08:35:38.194: vmx MKS REMOTE Loading VNC Configuration from VM config file

Aug 18 08:35:38.196: vmx The maximum resolution is therefore being limited to 1180x885 at 16 bits per pixel.

I then checked the .vmx for the problematic server and found that
svga.vramSize= 4194304.
Where as newly created VM has following setting for .vmx file
svga.vramSize=31457280
After investigation with the application owner we found that these are desktop modeling workstation and uses software from HP . HP has recommended this setting for their software to be functional.
One of the KB article explain that “Video Ram (VRAM) assigned to the virtual machine is 30MB or less”
Checked with HP support and they asked me to contact VMWare . When we contacted VMware they told that it is the limitation with ESX3.5 and had been taken care with ESX4.0 U1.
