Subject: [Libvirt] Failed to get udev device for syspath '/sys/devices/virtual/dmi/id'
Date: Wed, 23 Sep 2020 14:09:11 +0000	[thread overview]
Message-ID: <WBFXzWm02qaMoLNSOnDbHmebQchJ7xMXXT6ocR4SZ-6Pw8VClueBmTcHS3xHg_vttQRPdwdaHeNGskEHxHPETSSY03En7rejlTQ4lXhjlZk=@protonmail.com> (raw)

Hi,

I'm facing an issue with libvirt and the LIBXL driver, failing when searching for DMI data in /sys.

info : libvirt version: 5.0.0, package: 4+deb10u1 (Guido Günther <agx@sigxcpu.org> Thu, 05 Dec 2019 00:22:14 +0100)
error : udevGetDMIData:1719 : internal error: Failed to get udev device for syspath '/sys/devices/virtual/dmi/id' or '/sys/class/dmi/id'
error : libxlDriverConfigNew:1803 : Unable to configure libxl's memory management parameters
error : virStateInitialize:662 : Initialization of LIBXL state driver failed: internal error: Failed to get udev device for syspath '/sys/devices/virtual/dmi/id' or '/sys/class/dmi/id'
error : daemonRunStateInit:799 : Driver state initialization failed

The relevant function udevGetDMIData in libvirt:
https://github.com/libvirt/libvirt/blob/cb09344a2cccc0cc9bcefa3cb53d7af45ba92631/src/node_device/node_device_udev.c#L1726

I don't understand what's happening, as this initialization failure only happens when I boot on the Xen kernel.
Also, the /sys/class/dmi* paths are not exposed on Xen. (should they ?)

Note: Running on Xen 4.12.1

Any ideas ?

Thanks !
