Hi.
I'm having trouble getting the rosetta python projects task to work with an error at start.
I'm getting the error with the VBoxManager command.
I'm not sure why the error occurs only when I run the command from BOINC Client, while there is no error when I run commands such as
sudo -u boinc VBoxManage -q list hostinfo
directly.
boinctui says
Task aaae-mVAL_pp-TIQ_pp-mNMVAL-ACHA14C_2874422_9_1 postponed for 86400 seconds: Communication with VM Hypervisor failed. Communication with VM Hypervisor failed.

The following error is printed in /var/lib/boinc-client/slots/8/stderr.txt.
VBoxManage: error: Failed to create the VirtualBox object!
VBoxManage: error: Code NS_ERROR_SOCKET_FAIL (0xC1F30200) - IPC daemon socket error (extended info not available)
VBoxManage: error: Most likely, the VirtualBox COM server is not running or failed to start.

I built VirtualBox and Boinc from source.
$ boinc --version
7.21.0 x86_64-pc-linux-gnu

$ VBoxManage --version
7.0.0_ALPHA1r95556

(I am translating from Japanese by DeepL Translator. Sentence may not correct. Sorry.)

This thread is currently on "Cafe rosetta" topic,
but should be located at "Number crunching" topic?

Oh, sorry. Should I recreate this thread at "Number crunching" topic?

Maybe so :-)
Number crunching topic is more suitable for technical trouble, bug report, etc.

I seem to have found a workaround!

1. Open systemd unit file to edit
sudo systemctl edit boinc-client


2. In the new contents section, type
[Service]
PrivateTmp=true
then save and exit.

3. Reload systemd and restart boinc-client.
sudo systemctl daemon-reload
sudo systemctl restart boinc-client


reference : [Solved] Virtualbox and NS_ERROR_SOCKET_FAIL (LHC@home)

This worked for me and crunching some virtualbox tasks normally so far. Hope this helps.
