Description weizhang 2011-07-20 07:24:48 UTC

Description of problem:
connect the hypersior without configure tls/tcp environment, just do
# virsh -c qemu+tls:///system
will report
Segmentation fault (core dumped)

but libvirtd still alive. So I think it just reports wrong message.

Version-Release number of selected component (if applicable):
libvirt-0.9.3-6.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. virsh -c qemu+tls:///system
2.
3.
  
Actual results:
reports
Segmentation fault (core dumped)

Expected results:
reports reasonable message like
error: Cannot access CA certificate '/etc/pki/CA/cacert.pem': No such file or directory
error: failed to connect to the hypervisor

    Don't try to close a NULL virNetClientPtr
    
    * src/rpc/virnetclient.c: Skip close attempt if virNetClientPtr
      is NULL

Comment 8 xhu 2011-07-26 08:28:17 UTC

I have verified it on RHEL6u2 server with the following component and it passed:
libvirt-0.9.3-8.el6
qemu-kvm-0.12.1.2-2.172.el6
kernel-2.6.32-171.el6

The steps are as follows:
1 connect to localhost without tls configuration:
# virsh -c qemu+tls:///system
error: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory
error: failed to connect to the hypervisor
