rhel9 flakes: "ERR anaconda:anaconda: core.util: Timeout trying to start Xorg"

[rvykydal]

Last week we hit the timeout on RHEL 8 (https://github.com/rhinstaller/kickstart-tests/issues/848), this week on RHEL 9. Probably the same thing, but needs confirmation looking into logs. Attaching selected logs from 2 runs:

virt-install.log virt-install.log

First log has the same problem, glamoregl did not load after more than a minute.

Second log is bizarre. The same hang happens, but somehow we also simultaneously get the signal that the server is ready! Then it is not and it all falls apart.

03:24:22,881 NOTICE xserver:[   130.968] (II) Module glamoregl: vendor="X.Org Foundation"
03:24:22,881 NOTICE xserver:[   130.968] 	compiled for 1.20.11, module version = 1.0.1
03:24:22,881 NOTICE xserver:[   130.968] 	ABI class: X.Org ANSI C Emulation, version 0.4
03:24:25,251 DEBUG anaconda:anaconda: core.util: X server has signalled a successful start.

I did not look too deep but there are some search hits for the combination of glamoregl and SIGUSR1, which always mention investigating a crash. Perhaps it could be some weird side effect.
