no longer able to get NFS working

Postby MattyMatt » 25. Oct 2021, 16:26

(Mod Edit: this was formerly posted in "Using Virtualbox: Discuss the 6.1.28 release")

Hi. Wondering if anyone else seeing the something similar after the 6.1.28 release - am no longer able to get NFS working. Failing with an: 'RPC Error: Unable to Receive' when executing the command: 'mount -o vers=3,udp,actimeo=1 172.28.128.1:/System/Volumes/Data/Users/*****/*****/dev-instance/vagrant-fp/rp3 /var/www/*****/****'

Was working on 6.1.26, but no longer. Any suggestions welcome!

Host: MacOS 11.6 (BigSur)
Guest: Ubuntu 16.04 via Vagrant (latest)

Moved to Mac Hosts, because Vagrant is involved. Vagrant uses Virtualbox in ways we don't grok, so we don't support Vagrant-influenced Virtualbox. Vagrant has help forums, if you wish.

If you can get the error happening while starting a Virtualbox-only-driven VM, then we might be able to help.

Hey @MattyMatt, if you've recently upgraded to 6.1.28 then downgrade to 6.1.26. There's something wrong with host-only adapters in 6.1.28 that's causing issues. I first discovered through the NFS mounts and it spiralled from there.

For now the fix is to downgrade.

The behavior of Host-Only Networking has been changed. See 6.7. Host-Only Networking for details, especially the part below the text box.

Downgrade to 6.1.26 did the trick for me. Thanks for the suggestion!

Alternatively following the details at the end of the thread Virtual Box on Linux > Virtualbox-6.1.28 Does Not Assign IPs to HostOnly Network will resolve it.

Insane change for a patch version change and not at least a minor. Arg

Si-Matt probably refers to viewtopic.php?f=7&t=104198 where the info above from 'challengeursli' and some more bug workaround from 'aleksey-vb' gets host-only networks working again.

Yes thank you, couldn't post link due to account age.

Also, ensure you read the whole thing as the file can't contain empty lines for now. I made the file /etc/vbox/networks.conf with JUST the content

Code: Select all   Expand viewCollapse view
* 10.0.0.0/8 192.168.0.0/16 172.16.0.0/12
