Re: unaccessible directory in lxcContainerResolveSymlinks



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't exist.
Unfortunately, I am unable to reproduce - when I mkdir -p /flash/dir
and add corresponding <filesystem/> to one of my containers it boots up
just fine. What's your libvirt version?
