I tried to use the qemu upstream on xen Dom0 (arm arch) to get the PVFB,

2. " cd qemu "
3. configure using command "./configure

With Xen 4.5 qemu is automatically built for ARM, no need to do it
separately AFAIK.
Also note that you need to build qemu for i386, even on ARM

See my other replies. I think once we know how to deal with SELinux and

L3 event mask indicates the event types supported in host, including
cache occupancy event as well as local/total memory bandwidth events
for Memory Bandwidth Monitoring(MBM). Expose it so all these events
can be monitored in user space.

Jim, another idea: if those strings are likely to be wrong and in fact

including tests which could not be run:
test-amd64-amd64-xl-qemut-winxpsp3 7 windows-install fail REGR. vs. 26303
build-armhf-libvirt
With recent changes in p2m we now have legitimate cases when

The linear p2m changes in 3.19-rc1 is broken with some dom0
configurations. While trying to fix it I also noticed that
get_phys_to_machine() could be optimized for the common case.

The page table walk is only needed to distinguish between identity and
missing, both of which have INVALID_P2M_ENTRY.

If the non-RAM regions in the e820 memory map are larger than the size
of the initial balloon, a BUG was triggered as the frames are remaped
beyond the limit of the linear p2m. The frames are remapped into the
initial balloon area (xen_extra_mem) but not enough of this is
available.
Ensure enough

Applied to to stable/for-linus-3.
These changes were requested by Ian Campbell when relevant patches were posted
but they didn't warrant a resend at that time.
