dispVM shuts down immediately after starting (I'm trying to run xterm)

[floasretch]

On Qubes 4.0, when I try to start a dispVM, I get a popup notice that it's starting, then a popup that it started, then a popup that it halted. I get no error message, even when I specify --verbose:

[user@dom0 ~]$ qvm-run --verbose --autostart --dispvm=whonix-ws-dvm --service -- qubes.StartApp+xterm

Running 'qubes.StartApp+xterm' on $dispvm:whonix-ws-dvm

[user@dom0 ~]$

Is there a log somewhere to tell me what's going wrong?

The +xterm part should be a base name of .desktop file in
/usr/share/applications (or other directory per XDG standard). xterm on
Debian happens to have debian-xterm.desktop, so it should be
qubes.StartApp+debian-xterm.

Same result with qubes.StartApp+debian-xterm

Per your response, I verified that whonix-ws-dvm does have /usr/share/applications/debian-xterm.desktop (and whonix-ws-dvm itself starts and runs with no problem).

I've tried the same command on my whonix-ws-14-dvm and it works...
Is your whonix-ws-dvm Whonix 13, or updated to Whonix 14?

Whonix 14. Originally was 13 (installed with Qubes 4.0), then updated when 14 was released.

I verified /etc/whonix_version in both whonix-ws and whonix-ws-dvm. They're both 14.

BTW, I haven't been using disposable VMs at all for the past couple months, so I have no idea whether my problem is recent or old. In fact, the last time I did was with the Fedora DVM, and I've deleted it since then. Today was the first time I ever tried using any DVM other than Fedora.

Qubes and all templates are fully updated.

Is there a log somewhere?

You can add --pass-io, to see service stdout/stderr. Maybe this will
give some hints.

Alternatively, you can try doing the same in non-disposable VM, for example
whonix-ws-dvm itself. Simply drop --dispvm and add VM name before
service name, like this:
qvm-run --service -- whonix-ws-dvm qubes.StartApp+debian-xterm

And see if xterm will launch. Then, you can inspect ~/.xsession-errors
in that VM, or various logs in /var/log. If no terminal is started at
all, you can access VM console with `sudo xl console whonix-ws-dvm`
(exit with Ctrl+]).

vchan connection timeout

LOL. I changed qrexec-timeout for whonix-ws-dvm to 120 (from default of 60), and that fixed it.

Thanks.

A bit disturbing that 60 seconds isn't enough, though. It's a reasonably modern system. Intel Core i3 (Haswell generation) with 16GB RAM, and not overloaded. (CPU and disk are idle until I start the DVM, and not too many qubes are running.)
