[Xen-users] xenstore not working on custom kernel

[Sylvain Munaut <s.munaut@xxxxxxxxxxxxxxxxxxxx>]

Hi,


Somehow when I try to use a custom compiled kernel as Dom0, xenstore
doesn't behave properly :

bash# xenstore-ls
xenstore-ls: xs_directory (/): No such process

(and this in turns screws up the hotplug scripts).

Xen version is 4.7
Kernel version is 4.4.20

Any idea what's wrong ?


Cheers,

    Sylvain



For reference, the relevant kernel config :

bash$ grep XEN .config
CONFIG_XEN=y
