Hello, I'm running ovirt 4.4.10 and I have the following error while I launch a VM migration : Jul 3 12:37:07 ssc-sati-02 journal[958949]: Certificate [session] owner does not match the hostname myhostname Jul 3 12:37:07 ssc-sati-02 journal[958949]: Certificate check failed Certificate [session] owner does not match the hostname myhostname Jul 3 12:37:07 ssc-sati-02 journal[958949]: authentication failed: Failed to verify peer's certificate Jul 3 12:37:07 ssc-sati-02 journal[958949]: operation failed: Failed to connect to remote libvirt URI qemu+tls://myhostname/system: authentication failed: Failed to verify peer's certificate To avoid this error I set the following paramaters inside the /etc/libvirt/qemu.conf and restard vdsmd daemon. migrate_tls_x509_verify = 0 default_tls_x509_verify = 0 But I still have the same error. Can you help me to understand why this set of parameters are not working as exepected ? kind regards, Julien
