startd xen

Libvirt URI is: xen:///

Unable to connect to libvirt.

no connection driver available for xen:///

Verify that:
- A Xen host kernel was booted
- The Xen service has been started

Libvirt URI is: xen:///

Re: xen started ,but can't connect to libvirt

https://wiki.archlinux.org/index.php/Libvirt

[Libvirt]
Warning: Xen support is available but not by default. You need to use the ABS to modify libvirt's PKGBUILD and build it without the --without-xen option.

Re: xen started ,but can't connect to libvirt

This happened also on my KVM / qemu today after the upgrade. Rebooting or restarting doesn't do a thing.
However on my case libvirirtd loaded without issues.

Fixet after downgrade:

 pacman -U libvirt-1.2.21-1-x86_64.pkg.tar.xz 
loading packages...
warning: downgrading package libvirt (1.3.0-1 => 1.2.21-1)
resolving dependencies...
looking for conflicting packages...

and

pacman -U qemu-2.4.1-1-x86_64.pkg.tar.xz 
loading packages...
warning: downgrading package qemu (2.4.1-2 => 2.4.1-1)
resolving dependencies...
looking for conflicting packages...

Packages (1) qemu-2.4.1-1

Pretty bug.
