[libvirt] virDomainCreateWithFlags error

Hi all, I'm using 'libvirt 1.1.1-1 amd64' undef debian wheezy, I found that the return code is 139 when I run command: $ sudo virsh start df1c4670-18eb-4520-b5d8-aa8a492eb876 --paused; echo $? 139 but the return code is OK(0) when run command: $ sudo virsh start df1c4670-18eb-4520-b5d8-aa8a492eb876; echo $? I found there is an error in libvirtd.log: 2013-08-08 05:40:23.983+0000: 16626: error : virNetSocketReadWire:1377 : End of file while reading data: Input/output error I found this issue by using openstack nova folsom, if I create an VM by nova, it will use dom.createWithFlags(0) to create the VM, but then the nova-compute process exited when this function is called, then I changed the createWithFlags(0) to create(), everything become OK. I also tried the function under python, and the python process exited, too. but the dom.create() method is OK, so I think this is a problem about libvirt. I want to know is this a reported bug? libvirt and kvm hypervisor version: Compiled against library: libvirt 1.1.1 Using library: libvirt 1.1.1 Using API: QEMU 1.1.1 Running hypervisor: QEMU 1.1.2 Thanks 2012-08-16 Wangpan
