[HELP] Cannot start VM on truenas core


Hi, is there anyone here who has issues related to VMs on TrueNAS Core? I am having trouble booting a VM, and an error log message appears as shown in the following image.

for detail, here’s full error log:

Error: Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/middlewared/plugins/vm.py", line 213, in start
    if self.domain.create() < 0:
  File "/usr/local/lib/python3.9/site-packages/libvirt.py", line 1353, in create
    raise libvirtError('virDomainCreate() failed')
libvirt.libvirtError: Failed to open '/var/log/libvirt/bhyve/7_pfsense.log': No such file or directory

During handling of the above exception, another exception occurred:

    result = await self.middleware._call(message['method'], serviceobj, methodobj, params, app=self)

    raise CallError('\n'.join(errors))

VMs are not supported on CORE. But we could probably help sort this.

What are all the details?
VM type?
What are the settings you selected when installing the VM regarding CPU and such?

What version of CORE? I have a opnsense vm that boots/runs ok under TrueNAS-13.0-U6.1

As root:

mkdir -p /var/log/libvirt/bhyve
