Hi, I tried to build and run libvirt-1.0.1 on FSL PowerPC platform. The connection to '/var/run/libvirt/libvirt-sock' is always refused. # libvirtd -d # export LIBVIRT_DEBUG=1 # export LIBVIRT_LOG_OUTPUTS="1:file:virsh.log" # virsh -c qemu:///system list 2013-01-10 04:55:20.409+0000: 2574: info : libvirt version: 1.0.1 2013-01-10 04:55:20.409+0000: 2574: debug : virLogParseOutputs:1288 : outputs=1:file:virsh.log error: failed to connect to the hypervisor error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused Exactly it could work with libvirt-0.10.1. Below are the debug messages with both versions. # cat virsh.log ------------------------- 1). libvirt-1.0.1 ------------------------- <cut> 2013-01-10 06:12:12.107+0000: 2340: debug : do_open:1145 :
