VMWware Fusion Player 13 won't load existing bootcamp vm.

Hey, I've got a bootcamp VM that is running fine in Fusion 12, but try to load in 13 ( on Latest Ventura public beta, but had same issue in tech previews on Monterey too I think ) and I get the following:

Any idea on possible reasons for the error listed?

I seem to have the same issue.

...now I've done it! I tried deleting my Boot Camp and creating a new one. Fusion 13 says "Could not create the virtual disk for your Boot Camp virtual machine." So Fusion 13 lost access to something in Ventura. I had not tried the Boot Camp VM after I upgraded to Ventura so not sure if this was already broke or not?

Yeah mine won't create a new one either, though I haven't deleted the original, as it still works in 12.

I'm having the same issue. "Could not create the virtual disk for your Boot Camp virtual machine."

Same issue on my 2020 MacBook Pro. Just upgraded to Fusion 13 Player from 12. Bootcamp VM from my partition was working fine, no longer launching. I ended up deleting the BootCamp partition and created a new one, and now not able to create a new BootCamp VM.

Same here. Bootcamp VM won't boot after V13 upgrade.

Tried deleting it, and creating a new one but that process just fails (unsure how to get a full log, but happy to do it if someone tells me how).

For anyone blocked... I was able to uninstall V13, and install v12 again. It works as it should.

Add another person to the list experiencing this. I haven't updated to Ventura yet. I'm still runnung Monterey, so this seems to be a general Fusion 13 issue rather then something that is Ventura specific. I may revert back to Fusion 12 if no one has found a solution yet.

+1 here on MacBook Pro (15-inch, 2018), macOS 12.6.1 (21G217)

Tried the following troubleshooting suggestions to no avail, so downgraded back to Fusion 12 successfully.

Hmmm wondering if VMWare is aware of this regression. Seems like sending a bug report is not free (odd to me), so if anyone has an unlimited support plan... do us a favor hehe

gringley — Thu, 24 Nov 2022 23:59:31 GMT

I have opened a case with VMware. The initial troubleshooting session was almost pointless. What does appear to be going on is that something in Ventura has the bootcamp partition "open already" so Fusion cannot do anything with it.

Hmmm interesting that V12 is able to work for us

It's not just Ventura. Same thing happens in Monterey (12.6.1).

We are actively investigating a regression in VMware Fusion 13 which causes Boot Camp VMs to fail with the log containing the error message "DescriptorOpenExtents: Cannot open VMFS flat disk without an extent line". The same issue occurs either when powering on an existing Boot Camp VM or when attempting to create a new Boot Camp VM.

I do not yet have any information to share on possible workarounds. For the time being, it may be necessary to temporarily downgrade to Fusion 12 while we work on a fix. If you do downgrade and have other VMs besides the Boot Camp VM, please do remember to first downgrade the virtual machine's compatibility for each virtual machine by going to Virtual Machine > Settings..., then choose Compatibility, expand Advanced options, and if the virtual machine is using virtual hardware version 20, select version 19 or lower.

We are very sorry for the inconvenience.

please also investigate how such a lapse can happen during testing before releasing a major version
