Frontend directories are not been removed from store on {network,block}-detach. Makes xm {network,block}-list show closed devices. 2. Attach a block device after detach that does not work and does not report failure - Bug #420. 3. Frontend devices are not been unregistered on {network,block}-detach. Causes Bug #420. 4. If a domain die/crash/whatever all backend devices still on dom0. 5. xm {network,block}-{attach,dettach} does not check if operation was sucessfull on frontend. (ie. attach more than 3 vif fails, but xm network-attach does not report failure) 6. Attach more than 3 vif makes domU kernel OOPS. (probably drivers/xen/xenbus/xenbus_probe.c:307-308) Time to go. Tomorrow I will work on this errors again, and probably file bug reports for all of them. Thanks -- Murillo Fernandes Bernardes IBM Linux Technology Center
