This patch enables the possibility to run a qemu virtual machine with the
share option for the memory-backend-file. The xml description looks like:
<memdev type='file' share='on'>
<name>ram0</name>
<source mem-path='/hugetlbfs'/>
<capacity unit='MiB'>1024</capacity>
</memdev>
This work is based on the previous work of Chen Fan[1].
We are aware of the existing conflict with the previous numa patches[2].
We are sharing this because it is a dependency for some use cases of the
qemu vhost-user support(e.g. snabbswitch).
