Hi all
We use libvirt 1.2.x and 1.3.x with next filesystem definition in config:
<filesystem type='ram' accessmode='passthrough'>
<source usage='524288' units='KiB'/>
<target dir='/dev/shm'/>
</filesystem>
But libvirt 2.1.0 with same config report error:
Failed to access '(null)': Bad address

Someone use libvirt 2.x with /dev/shm device ?
Probably need change config and add some definitions to /dev/shm ?
it is a bug introduced in 2.1.0 - i've just copied you on a patch
that should fix it. If possible, it'd be good if you can build with
that patch and report whether it works for you

Daniel
