[Xen-devel] Issue while bringing up libvirtd.service

[Praveen Kumar <kpraveen.lkml@xxxxxxxxx>]

Hi,

I am new in Xen environment and trying to get VMs running with the build xen code base.

But, am facing issue bringing up the libvirt deamon. I have installed latest unstable xen ( 4.9 ).

There seems to be a conflict in library version and because of which I am getting below error :

...

Dec 08 00:44:43 kpraveen.labs.blr.novell.com libvirtd[14603]: Unable to configure libxl's memory management parameters

Dec 08 00:44:43 kpraveen.labs.blr.novell.com libvirtd[14603]: Initialization of LIBXL state driver failed: no error

Dec 08 00:44:43 kpraveen.labs.blr.novell.com libvirtd[14603]: Driver state initialization failed

...

The problem is resolved when I remove libvirt-daemon-driver-libxl, but that seems to be removing libvirt package also and causing below error during vm-install :

....

Dec 08 00:41:59 kpraveen.labs.blr.novell.com libvirtd[7005]: no connection driver available for xen:///

Dec 08 00:41:59 kpraveen.labs.blr.novell.com libvirtd[7005]: End of file while reading data: Input/output error

....

I found that we have xen-libs of different version which is 4.7, but don't know if that is the root cause and how to upgrade that. As suggested, I have also rebuild xen tree and tried reinstalling, but the issue persists.

Any guidance will be very much helpful to resolve this problem . Also, wanted to know, what others follow as best practices when there is a version change or if hit the similar problem.

Just FYI, I am following https://wiki.xenproject.org/wiki/Compiling_Xen_From_Source link for compiling and installing xen.

Thanks in advance.

Regards,

~Praveen.
