Any ideas what this error is? I recently moved this VM from one ESXi server to another using the vCenter Converter Standalone (as I've done for several other VMs-succesfully). I get this popup when I try to power on the VM
Are you using ESXi 6.5 ?
Check vm's vmware.log and /var/run/log/vmkernel.log files.
Check if ATS heartbeat is enabled on ESXi hosts and disable same. Refer VM KB: File system specific implementation of LookupAndOpen[file] failed: VDI machine (2149438)
Also, check this 3rd party blog: Cannot start Virtual Machine on ESXi 6.5
If the above doesn't work, refer to this VM KB: Race condition on ESXi 6.5 causing disruption to VMs or hostd management service (50372)
Please provide a complete list of files in the VM's folder.
In order to see all files (including hidden ones) connect to the host using WinSCP (you'll need to enable the SSH service on the host).
In addition to the file list, attach all .vmdk descriptor files (the small ones without flat/delta/sesparse in their names) to a reply post.
