[libvirt] qemu-kvm blocked for more than 120 seconds when "libvirt-guests" is enabled

[Oscar Segarra]

Hi,

I have modified libvirt-guests.service in order to add a dependency for the
ganseha service.

After=network.target libvirtd.service time-sync.target *nfs-ganesha.service*
*Requires=nfs-ganesha.service*

But it looks system does not stop vms:

Any help will be welcome!

Thanks a lot.
