I am now wondering if we should do this in a different way. ie if there is some XML configuration parameter for the <disk> that indicates the need for rawio, then libvirt could automatically ensures that we add CAP_SYS_RAWIO when starting QEMU.
I see. You say if a guest has the following XML configuration, "CAP_SYS_RAWIO" capability is automatically added to it, right?
<disk type='block' device='lun'>
Yes, that actually seems reasonable, especially since device='lun' is brand new, and so far, is really the only reason that we'd need CAP_SYS_RAWIO. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
