I still have a Q.. for qemu-nbd exporting over Unix socket.. what should i put for port attr of <host> tag ? I am assuming its ignored for Unix sockets ? It's not required anymore. In fact it was a bug that transport='unix' was accepted in the old libvirt, because it didn't know how to process it.

I tried with the latest git version of libvirt (1.0.5). I still get the same error for trying to attach nbd device, where as file based device works. ./daemon/libvirtd --version /home/dpkshetty/work/newlibvirt2/libvirt/daemon/.libs/lt-libvirtd (libvirt) 1.0.5 My qemu-nbd exports the disk as... qemu-nbd -t -k /tmp/mysock2 /home/dpkshetty/work/img/iscsi_disk 1) My libvirtd started as ./run ./daemon/libvirtd and in this console i see... error : qemuMonitorTextAddDrive:2691 : operation failed: open disk image file failed 2) My python example ( I tried with virsh (started as ./run ./tools/virsh...) - see same error)

3) In nbdxml, i tried removing port="1111".. it didn't give any error with regards to port beign mandatory.. which si good.. but the attach device still gives the same error as above Is the `nbdxml` I am using for attachign a qemu-nbd exported drive, correct ? thanx, deepak
