Package: xen-hypervisor-4.4-amd64 Version: 4.4.1-9 Severity: grave Justification: renders package unusable
Hi, I was running Debian Wheezy (amd64) and xen-hypervisor 4.1 on a Dell PowerEdge R720. Xen was working fine. Xen was configured with LVM Now, I'm trying Debian Jessie (amd64) and I have a strange problem. After booting, Xen seems to be working : /etc/init.d/xen status ● xen.service - LSB: Xen daemons Loaded: loaded (/etc/init.d/xen) Active: activating (start) since sam. 2015-05-29 23:20:50 CEST; 33s ago Control: 1150 (xen) CGroup: /system.slice/xen.service ├─1150 /bin/sh /etc/init.d/xen start └─1229 xenstore-write /local/domain/0/name Domain-0 mai 29 23:20:50 jango xen[1150]: Starting Xen daemons: xenfs xenstored mai 29 22:20:50 jango xen[1150]: Warning: Fake start-stop-daemon called, doing nothing. mai 29 23:20:50 jango xen[1150]: Warning: Fake start-stop-daemon called, doing nothing.

Have you any clue about this problem ? Is there anything I can test to debug this ? Thanks a lot.
