changing from: <driver name='file'/> to: <driver name='tap2'/> makes the domain start without QEMU.
However I see much better performance with QEMU (close to dom0, tested using simple dd writes) than with tap2 driver. Is that expected?
How did you measure it? buffered or direct io?

What's best practise to file based storage on latest CentOS6-xen (Kernel 3.18.17, Xen 4.4.2-7)
Are there any guides around running QEMU on CentOS6-xen as non-root user?
Cheers

Hi, after migrating to libvirt/libxl according to:
Hi,
https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt
I've noticed that my Xen PV domains are being launched by qemu-system-i386 running under root privileges.
I am wondering why is this? Previously no qemu process was used.
If qemu is needed for some reason, are there any guidelines for non-root operation?
In general qemu is used for the following purposes:
- for certain domU disk backend types (image files), and/or if there's
no blktap driver in dom0 kernel.
- domU graphical console (PVFB) VNC server, if it's enabled for the domU.
