Does someone know how it is possible these parameters:

I use them with xl config but I want to change to libvirt config/tools.

Hi
wich tuned profile are the best for dom0 and domU?
There are virt-host and virt-guest profiles for kvm, should I use them?
If yes, should I use in domU ever virt-guest or is for example
network-throughput profile better for a nfs/samba fs server inside domU
better?

Hi
could you add pv grub2 images to the packages?
I've tried it following this howto:
https://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/
and it works really good...
It would be nice to have it in the rpm packages.
