Description of problem:
vdsmd.service fail to start with lasted libvirt(libvirt-3.2.0-4.el7.x86_64
), because libvirt use GSSAPI (kerberos) instead of the insecure DIGEST-MD5 as a default mechanism. Using old configuration vdsmd can start successfully.

libvirt-3.2.0-4.el7.x86_64

How reproducible:

Steps to Reproduce:
1. Install libvirt, vdsm packages
2. 
#vdsm-tool configure --force

#systemctl restart vdsmd       
Job for vdsmd.service failed because the control process exited with error code. 

3.
#vdsm-tool -vvv is-configured  
Current revision of multipath.conf detected, preserving
......
libvirt is already configured for vdsm
Modules passwd are not configured
Error:  

One of the modules is not configured to work with VDSM.
......

4. change libvirt.conf in sasl2 and use the old configuration: 

#vim /etc/sasl2/libvirt.conf
......
mech_list: DIGEST-MD5
sasldb_path: /etc/libvirt/passwd.db
......

#systemctl restart vdsmd

vdsmd service can start successfully.

vdsmd.service fail to start
