[libvirt] [PATCH 0/2] memdev device: add share argument for type=file

[Michele Paolino]

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).
