Hi,

If I try to add only /flash (without dir subdirerctory) into the XML, it
works fine for me.
Does it matter what sort of permissions(user/grp) /flash/dir has?

Thanks
Priyanka

Yeah, the lxc driver thinks that /flash/dir doesn&#39;t exist.<br>
Unfortunately, I am unable to reproduce - when I mkdir -p /flash/dir<br>
and add corresponding &lt;filesystem/&gt; to one of my containers it boots up<br>
just fine. What&#39;s your libvirt version?<br>
