qvm-run doesn't work on systemd system-sleep scripts

[gasull]

Qubes OS version:

Qubes release 4.0 (R4.0)

Affected component(s):

---

Steps to reproduce the behavior:

In dom0:

$ sudoedit /usr/lib/systemd/system-sleep/suspend-resume.sh
$ chmod 755 /usr/lib/systemd/system-sleep/suspend-resume.sh
$ cat /usr/lib/systemd/system-sleep/suspend-resume.sh
#!/usr/bin/env bash
qvm-run --pass-io --verbose my-qube "echo hi" 2>&1 | systemd-cat -t suspend-resume
$ /usr/lib/systemd/system-sleep/suspend-resume.sh
$ journalctl --identifier=suspend-resume
-- Logs begin at (...) --
Jul 23 2:41:47 dom0 suspend-resume[7846]: Running 'echo hi' on my-qube
Jul 23 2:41:47 dom0 suspend-resume[7846]: hi

Close laptop, wait for it to suspend, open it again, then, in dom0:

$ journalctl --identifier=suspend-resume
-- Logs begin at (...) --
Jul 23 2:41:47 dom0 suspend-resume[7846]: Running 'echo hi' on my-qube
Jul 23 2:41:47 dom0 suspend-resume[7846]: hi
Jul 23 2:43:16 dom0 suspend-resume[7897]: Running 'echo hi' on my-qube
Jul 23 2:43:21 dom0 suspend-resume[7897]: vchan connection timeout
Jul 23 2:43:34 dom0 suspend-resume[7932]: Running 'echo hi' on my-qube
Jul 23 2:43:39 dom0 suspend-resume[7932]: vchan connection timeout

Expected behavior:

The command echo hi should execute in my-qube and therefore journalctl on dom0 should return this instead:

Jul 23 2:43:16 dom0 suspend-resume[7897]: Running 'echo hi' on my-qube
Jul 23 2:43:21 dom0 suspend-resume[7897]: hi
Jul 23 2:43:34 dom0 suspend-resume[7932]: Running 'echo hi' on my-qube
Jul 23 2:43:39 dom0 suspend-resume[7932]: hi

Actual behavior:

As said, journalctl on dom0 shows echo hi wasn't executed:

Jul 23 2:43:16 dom0 suspend-resume[7897]: Running 'echo hi' on my-qube
Jul 23 2:43:21 dom0 suspend-resume[7897]: vchan connection timeout
Jul 23 2:43:34 dom0 suspend-resume[7932]: Running 'echo hi' on my-qube
Jul 23 2:43:39 dom0 suspend-resume[7932]: vchan connection timeout

General notes:

I tried other commands, like writing on the journalctl of my-qube or writing a file in my-qube. They work from the comand line in dom0, but not in the script for system-sleep.

All qubes are suspended/paused for the host suspend time, so at this point it is impossible to interact with them. You can work around this by creating new service ordered before qubes-suspend.service. See systemctl cat qubes-suspend.service for example settings.
