I know this is probably basic for many of us but I think you should add to make executable the agent :

Code:

chmod +x /usr/local/bin/qemu-ga
chmod +x /sourcepath/qemu-guest-agent

 

[mrdindon]

Btw, thank :) I just adapt it for PfSense :)

PfSense VM on ProxMox : Qemu-agent installation

Update procedure for PfSense 2.6.0 (Shell) Install Qemu-agent package : pkg install qemu-guest-agent (web gui): Install "Shellcmd" from the package manager ...

Glad people are finding it useful.

I wasn't aware about making those files executable. It’s not something I did and it’s still working.

Is this something that only the people who download it will need to do perhaps?

I can't tell but I think it definitely should.

Hi I couldn't found the zip files link. Where is it ? Would you mind post it again ?

 

[andrema2]

Found it. I had to go to history and I could see a download link

Thanks

Unfortunately the agent is not working anymore in TrueNAS-13.0-RELEASE (CORE)
When doing

kldload virtio_console.ko

I get

pid 1328 (syslog-ng), jid 0, uid 0: exited on signal 6 (core dumped)
KLD virtio_console.ko: depends on kernel - not available or version mismatch
linker_load_file: /boot/modules/virtio_console.ko - unsupported file type

Which seems due to a discrepancy between the module and the kernel as stated here :

KLD Load - depends on kernel - not avail. or version mismatch

I'm developing a device driver kld module to be hooked up to the FreeBSD system. Using a very simple default "hello" driver found below, I'm trying to kld load the module. However I'm getting the error: KLD hello.ko: depends on kernel - not available or version mismatch linker_load_file...

forums.freebsd.org

A recompile against latest kernel version seems required.

That's because /boot/modules/virtio_console.ko isn't packaged with TrueNAS 13.0-RELEASE. It's also not compiled-in, from what I can tell by running sysctl -a | grep virtio.

Is there any chance of someone being able to address this issue ? Guest agent integration was working extremely well prior to 13.0. It is quite a bummer to have lost this integration.

None of the moderators on this forum can help. Use the Report a Bug link to send a report to the developers.

 

[zamana]

It was reported?

I'm interested on this also.

 

[jhollowe]

I've built new versions of the files for TrueNAS 13. Uses the same instructions, just works with the new version of FreeBSD

 

[jhollowe]

(and check out the Resource I made for any questions)

 

[baggis]

this is maby a dumb question.... but how do i transfer the files?
im useing filezilla, but only the virtio file is accepted? the other files just failed to transfer

 

[jhollowe]

If you are trying to use filezilla to put them in their final place, destination permissions might be the issue. Try copying the files to your home directory (or somewhere else you have permission to create files) and then sudo cp the files into their final destinations

I just found your thread and finally got this set up on my TrueNAS servers.

I wrote a script to do the whole thing. Do you mind if I make it public on GitHub?

 

[Deeda]

Works great, thanks. I was wondering if I should make a feature request for this to be included? Or is that being naive? If not supported by FreeBSD out of the box, does that make it more difficult to include with a default TrueNAS Core install?

 

[Roopee]

Unfortunately it didn't work for me on TrueNAS-13.0-U5.1 running on PVE 7.4-16 using the resources above and these installation instructions precisely (I put qemu-guest-agent in /usr/sbin for the cp command since it didn't say/matter exactly where, and set permissions to -r-xr-xr-x)

While checking/trying to troubleshoot I tried starting the qemu-guest-agent service at the console as root and got:
Segmentation fault (core dumped)
/usr/local/etc/rc.d/qemu-guest-agent: WARNING: failed to start qemu-guest-agent

If anyone has any troubleshooting ideas I'd be interested, but it isn't critical since as far as I can tell TrueNAS does shutdown or reboot properly when PVE tells it to (is there a way to check definitively?) - perhaps because the VM is using CPU=host?

 

[Deeda]

Heya Roopee, I have it working on TrueNAS-13.0-U5.3 and PVE PVE 7.4-16. Did you use the updated versions from jhollowe's post above?
