This was originally an 24.04 install, with no apps or services, that I upgraded to → 24.10. Under 24.04, qemu-guest-agent did not start either.
I have another heavily-used TrueNAS instance that was originally 22.04 that I’ve upgraded to → 23.04 → 24.04 → 24.10. That one has qemu-guest-agent starting normally the entire time.
dmesg nor /var/log/messages do not have anything QEMU related, except for the following which is identical, including nearly the 35 second timestamp, on both TrueNAS instances, including the one it is working on. So this means nothing:
# dmesg | grep qemu
[ 0.000000] DMI: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014

Are there any other logs to look at?
