re: xenconsoled defunct after xl create on fresh debian 12

[Pry Mar <pryorm09@xxxxxxxxx>]

Hello,

https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=tools/hotplug/Linux/init.d/xencommons.in;h=7fd6903b9868e27f855ba797a2529e6e2171d089;hb=refs/heads/staging-4.17

It seems your distro xen-4.17 uses the init scripts for xen services, not systemd. The above branch in xen.git shows where/how xenconsoled is started. It does

write a PID for xenconsoled.

Note that the systemd service for xenconsoled has no such PID. However, I suspect you have a stale PID for xenconsoled, check the write time against the other xen PID's.

I have a build of xen-4.17.3 running on Bookworm that uses the systemd services. See above.
