[libvirt] libvirt-libxl driver defaulting to tap disk and not working (ubuntu 12.10 + xen 4.5 + libvirt 1.2.3 + openstack)
HI I am an openstacker, when I used the latest libvirt and xen code to run the openstack. Can not create the vm. there is an error in libxl log, you can see the log: Os : Ubuntu 12.10 Compiled against library: libvirt 1.2.3 Using library: libvirt 1.2.3 Using API: Xen 1.2.3 Running hypervisor: Xen 4.5.0 libxl: debug: libxl_create.c:1356:do_domain_create: ao 0x7f7894002810: create: how=(nil) callback=(nil) poller=0x7f7894001bb0 libxl: debug: libxl_device.c:251:libxl__device_disk_set_backend: Disk vdev=xvda spec.backend=tap libxl: debug: libxl_device.c:210:disk_try_backend: Disk vdev=xvda, backend tap unsuitable because blktap not available libxl: error: libxl_device.c:289:libxl__device_disk_set_backend: no suitable backend for disk xvda libxl: debug: libxl_event.c:1739:libxl__ao_complete: ao 0x7f7894002810: complete, rc=-3 libxl: debug: libxl_create.c:1370:do_domain_create: ao 0x7f7894002810: inprogress: poller=0x7f7894001bb0, flags=ic libxl: debug: libxl_event.c:1711:libxl__ao__destroy: ao 0x7f7894002810: destroy The blktap does work, and I also find the same error someone has posted, (http://www.redhat.com/archives/libvir-list/2013-February/msg01124.html) When I change the type to phy, it also doesnot work. And try to change the type to other options, also does not work. Can someone give me some suggestions? Thanks !

Perhaps try tap or just leaving the driver as default? jch -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
