[Fedora-xen] Adding qemu disable pci devices patch to Fedora Xen
Hello.
Would it be possible to add Qemu "disable pci devices" patch to Fedora Xen
packages? It allows HVM domains (or more specifically PV drivers running
in HVM domains) to hide qemu emulated disk/network devices in a sane way to
prevent possible corruption and other problems when both the PV devices and Qemu
emulated devices are present at the same time..
It's mostly needed for Xen gplpv drivers by James Harper. The same
code/feature is also being used by Citrix/Xensource commercial Windows PV
drivers.
The patch has been in xen-unstable (3.4) for a while already without
problems.
Patch against Xen 3.3.1 (by James Harper):

Discussion about it on xen-devel:

This would be a needed feature soon when HVM domains start working ok with
pv_ops dom0 :)
