Update and error on QMP socket

[Ronny Wagner <starchip2000@xxxxxx>]

Hello,

today i update (compile) my Debian Bullseye Server from xen 4.15.1 to
4.16.0 and i see a fail message when i start my DomU's.

Fail:

arsing config from /etc/xen/domU.cfg
libxl: error: libxl_qmp.c:1400:qmp_ev_fd_callback: Domain 1:error on QMP
socket: Connection reset by peer
libxl: error: libxl_qmp.c:1439:qmp_ev_fd_callback: Domain 1:Error
happened with the QMP connection to QEMU
libxl: error: libxl_dm.c:3351:device_model_postconfig_done: Domain

libxl: error: libxl_create.c:1867:domcreate_devmodel_started: Domain

libxl: error: libxl_domain.c:1064:domain_destroy_cb: Domain

With following steps:

- download xen-4.16.0.tar.gz

- untar

- ./configure --enable-systemd

- make PYTHON=/usr/bin/python3 -j8 dist

- make PYTHON=/usr/bin/python3 -j8 world

- stop the xen services (xen-qemu-dom0-disk-backend.service,
xen-init-dom0.service, xenconsoled.service, xenstored.service,
xendomains.service)

- make PYTHON=/usr/bin/python3 -j8 install

- reboot server

Have anyone a idea what is here happend? And the important question, how
can i solve the problem?

Thank you very much.
