VMWare - Hyper-v migration fails, file read error

[CZFan]

Hi,

I am in the process of migrating various VM Guests between various physical VM Hosts for a client, from VMWare ESXi to Hyper-V 2019 Core server using StarWind V2V tool (Awesome tool by the way)

Some of the VM Guests migrate without any issues, so I suspect there is no issues with either VMWare side or the Hyper-V side. I have searched the www, find many people reporting similar issues, but not finding a solution. Below extract from V2V log re error I get:

7/13 11:28:18.194 24b4 Facility ???INFO: CPPConverting::ConvertImage: CreateOutputImage: 0
7/13 11:33:32.257 24b4 Facility ???ERROR: VMwareFile::Read: m_VixDiskLib_Read is fail - 13, You do not have access rights to this file

Any help and or workaround to get these boxes migrated will be highly appreciated.

Please let me know if additional information is required.

Hi,
Welcome to StarWind Forum and thanks for your kind words
See if the file is locked by anything else or is in use.

Thx for quick reply.

Process I follow is:
shutdown guest vm on vmware
migrate to hyper-v using V2V tool
during "converting..." process I get this error, with guest vm in shutdown state, I doubt that the file will be in open state?

As a workaround, please copy that disk to the Hyper-V host and convert it as a local file.

Not sure I followed you correctly, sorry, not so clued up / much experience on VMWare, but tried the following

Tried to download the disk image from ESXi web interface, but it does not seem to download correctly, i.e. size does not match up, only shows something like 1KB.

So did an "Export" of VM Guest in VMWare, which completed 100% successful according to web interface on VMWare, but running V2V, it gives error, below screenshot of error and also log file contents. Not sure how to move forward here

Copy only the disk to the destination Server (i.e., Hyper-V and convert it as a local file (VMDK -> VHDX)). You will need to recreate that VM.

@yaroslav (staff)
Thx for your responses.

I suspect there is something wrong with that datastore, even unable to copy the file within same datastore but different directory, get general I/O error in datastore browser.

So these server migrations on hold for now.

Hi,
You are always welcome
That could be VMFS-level corruption. Please try copying data off the datastore and reformatting it, look if VOMA fixes anything, or run some vmfs repairs.
