More installations are effected (see https://askubuntu.com/questions/1324283/unable-to-add-disk-devices-for-domu-after-kernel-update-5-4-0-67).

Running Ubuntu 20.04.2 LTS with xen 4.11

After the last kernel update 5.4.0-67 and a server restart none of the guests were started. Trying to start a domU manually I got the following error message:

libxl: error: libxl_device.c:1130:device_backend_callback: Domain 8:unable to add device with path /local/domain/0/backend/vbd/8/51712 libxl: error: libxl_create.c:1299:domcreate_launch_dm: Domain 8:unable to add disk devices libxl: error: libxl_device.c:1130:device_backend_callback: Domain 8:unable to remove device with path /local/domain/0/backend/vbd/8/51712 libxl: error: libxl_domain.c:1107:devices_destroy_cb: Domain 8:libxl__devices_destroy failed libxl: error: libxl_domain.c:1034:libxl__destroy_domid: Domain 8:Non-existant domain libxl: error: libxl_domain.c:993:domain_destroy_callback: Domain 8:Unable to destroy guest libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 8:Destruction of domain failed

Only reverting to the previous kernel 5.4.0-66 solved the problem.
