[libvirt-users] Libvirtd dead, pid still exists. ( Problem might be with TLS interface of libvirtd )

Dear All, Please find few minutes from your time and guide us with some pointers if possible. We are facing a libvirtd crash when we are trying to connect to qemu by default TLS transport. # virsh -c qemu+tls://localhost/system version error: authentication failed: TLS handshake failed A TLS packet with unexpected length was received. error: failed to connect to the hypervisor I used my own CA and certificates (generated using http://libvirt.org/remote.html#Remote_libvirtd_configuration on Redhat PC) on both Kontron PC and our Board (with patched libvirt). Libvirtd.conf was modified so that libvirt is listening all IPs using default IP (so that it was possible to use same certificates on all machines) These directories and files created and used. /etc/pki/CA/cacert.pem /etc/pki/libvirt/private/serverkey.pem /etc/pki/libvirt/servercert.pem /etc/pki/libvirt/private/clientkey.pem /etc/pki/libvirt/clientcert.pem TLS connection worked fine with Kontron PC # virsh -c qemu+tls://localhost/system version Compiled against library: libvir 0.9.5 Using library: libvir 0.9.5 Using API: QEMU 0.9.5 Running hypervisor: QEMU 0.12.1 But libvirt crashed on our Board (using libvirt 0.10.2, gnutls-2.10.5-1_WR4.3.x86_64 and libudev-161-4 rpms ) # virsh -c qemu+tls://localhost/system version error: authentication failed: TLS handshake failed A TLS packet with unexpected length was received. error: failed to connect to the hypervisor GDB: Program received signal SIGABRT, Aborted. 0x00007f8591246005 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007f8591246005 in raise () from /lib64/libc.so.6 #1 0x00007f8591248e40 in abort () from /lib64/libc.so.6 #2 0x00007f8592a2fdc5 in ??

If not, I will raise a new bug for the same. ( Atleast I coulnt find the the known issues ) Thanks and Regards, Shree Duth Awasthi.
