Any reason as to why you recommend Fedora instead of a distro with a smaller foot print like Debian?

Because if it were me I want all the extra preformance I could get if I were gaming on a VM.

Yeah but stable also means outdated you might have to rebuild your kernel anyway

@ Bobicon
It doesnt matter which distro you use, dom0 is just a privileged VM in the end, the cpu's you see are actually threads on the xen hypervisor as far as i understand, the only advantage as you point out might be memory footprint, but you can limit dom0 max memory anyway.

I'd like to make a correction, the windows installer under DUET on EFI mode only crashes if 'xen_platform_pci = 1' y changed it to 0 and it worked biggrin.gif, after that i reverted it to 1 and windows is happy with it, so you dont need a uefi mobo to install and run windows on uefi mode after all.

@nbhusain: Thanks for the update - this sounds more and more intriguing.

@Bobicon: I think this is both a matter of preference and available hardware. If you have enough RAM and a modern 4+ core CPU, the resources that the dom0 uses are negligible, regardless of the distro. Memory is cheap so giving the dom0 2GB (or more) of RAM shouldn't cost too much.

For I/O performance it is advisable to give dom0 enough memory and CPU (vcpu) to make sure it doesn't turn into a bottleneck.

It makes perhaps sense to have a small "console only" dom0 and run both the Linux DE and Windows in VMs, if only for security reasons. But in that case you would probably need to passthru 2 VGAs to get good graphics performance for Linux and Windows.

Yup, done that under gentoo, the downside is you will always have to allocate at least 1 cpu to dom0 and if something goes wrong, you're on blind mode, thats why im doing this experiment with duet, i always have access to my dom0 and even under heavy load it doesnt affect windows at all.

Did you build pciback as a module?

nope, build-in.

In anycase when I have time again I'll try building 4.1 and see what happens

check if this folder exists /sys/bus/pci/drivers/pciback/
