Last week I encountered some issues with converting a Hyper-V 2008 R2 virtual machine to VMware vSphere 5.5 using VMware Converter 6.0.
Before attempting the conversion I first disabled SSL encryption within VMware Converter (kb.vmware.com/kb/2020517) to help improve the conversion speed. I then proceeded to configure VMware Converter using the default settings for the source and destination VMs.
The converter process started OK however at 33% completion the job had failed with the following error: “An error occurred during the conversion: ‘The operation experienced a network error’“.
At this point I had also noticed that my destination ESXi host had also disconnected from vCenter. After a few minutes the host began to respond and I had noticed it too had an error, “/sbin/hostd crashed (1 time(s) so far) and a core file might been create at /var/core/hostd-worker-zdump.000. This might have caused connections to the host to be dropped.“
