vMotion – A general system error occurred


Updated 20170127

Apparently this applies to vSphere 6.5 as well according to a comment below.

Thanks Joe for letting us know


The other day i had an issue with vMotion migrations in my vSphere environment running the following versions:

  • vCenter Server 5.5.0 build 2183111
  • ESXi 5.5.0 build 2143827

The error i was seeing happened at the magic 14% threshold and the errors i saw were:

  • A general system error occurred: Migration to host X.Y.Y,224 failed with error Busy (0xbad0004)
  • Migration to host X.Y.Z.224 failed with error Busy (195887108)


There are a bunch of VMware KB regarding vMotion failure at 14% and here are a few:

After a lot of troubleshooting including reading a bunch of log files and a few configuration changes i came across VMware KB 1031636 which talks about “vMotion fails with the error: remote host IP_Address failed with status Busy (1031636)”.
Even though KB 1031636 is for ESX/ESXi 4.1 i decided to give the Migrate.VMotionResolveSwapType config change (use 0 instead of the default value 1) a try and after the change all vMotion processes completed successfully.

VMware will update KB 1031636 to include vSphere 5.5 as well.

    I got the same issue (vCenter 5.5 build 2001466 and ESXi 5.5 build 2143827) and changing Migrate.VMotionResolveSwapType from 1 to 0 resolved the issue.

    VMware did however not yet update KB 1031636 to include vSphere 5.5

    What could be the possible downside of setting Migrate.VMotionResolveSwapType to 0? In oyther words, why would one not set this option by default to 0?
