Hello all, I'm a newbie to libvirt, coming to it because I'm trying to understand how to provide the ability to attach/detach network filesystem shares to openstack guest instances in something analogous to the way block devices can be now. While playing with the existing virtfs/9p support for qemu, I found that I can't use virsh to attach a "filesystem" device while the VM is running. For example, I create a snippet of XML like <filesystem type='mount' accessmode='mapped'> <source dir='/tmp/share'/> <target dir='share_tag'/> </filesystem> and then try: stack@devstack-8366:~/devstack$ virsh list Id Name State ---------------------------------------------------- 3 instance-00000002 running 5 instance-00000004 running 8 instance-00000007 running stack@devstack-8366:~/devstack$ virsh attach-device 8 share.xml error: Failed to attach device from share.xml error: Operation not supported: live attach of device 'filesystem' is not supported I see that error coming from src/qemu/qemu_driver.c in the qemuDomainAttachDeviceLive function. Can anyone tell me if this is something that is going to be hard or easy to make possible? Pointers to where I should look in the source, or in qemu? Is anyone working it already? Any advice at all welcome, Thanks -Emile Snyder -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
