Hi,
the Xenstored service is failing during boot because it can't find gnttab during boot. But the file /usr/lib/libxengnttab.so.1.2 is there and if I manually start /usr/sbin/xenstored or /etc/xen/scripts/launch-xenstore it works. Does anyone have an idea
why xenstored can't find the library during boot, but can find it after the boot?
This is the Xenstored service status after booting:
* xenstored.service - The Xen xenstore
