I got this reproduced when retrying again for another case-
Actually not too hart to hit :-/
Taking a Focal system with the version of qemu-guest-agent you reported
and then making sure it is installed, up and running:
● qemu-guest-agent.service - QEMU Guest Agent
Loaded: loaded (/lib/systemd/system/qemu-guest-agent.service; static;
vendor preset: enabled)
Active: active (running) since Tue 2020-06-02 05:25:04 UTC; 3min 8s ago
Main PID: 624 (qemu-ga)
Tasks: 1 (limit: 533)
Memory: 900.0K
CGroup: /system.slice/qemu-guest-agent.service
└─624 /usr/sbin/qemu-ga
Pass a shutdown command through virsh:
$ virsh shutdown focal --mode agent
The guest almost immediately went down, without "functional" issues.
But when checking the logs later I found:
Jun 02 05:29:54 focal qemu-ga[624]:
ERROR:/build/qemu-74sXTC/qemu-4.2/qga/main.c:532:send_response: assertion

Completely new/fresh focal / mate install. Crash during initial apt install
of many packages after first log-in, including qemu-guest-agent. No other
important load other than apt running. OS running in a vm as a guest
(obviously...) No idea what caused it. Including crash report.
- VM was 2 penryn class cpus with 3G ram.
