HI!!!!!!

I found a workaround!!!!!!!!!!!!!!!!

the brocker process try to connect to vdsm to IPV4 host address using an 
IPV6 connection
(I noticed that doing a strace to the process),
but ipv6 is not intialized at boot. (why connect to IPV4 address using 
IPV6?)

I added the following lines to crontab:

@reboot echo 'echo 0 > /proc/sys/net/ipv6/conf/lo/disable_ipv6' | 
/usr/bin/at now+1 minutes
@reboot echo 'echo 0 > /proc/sys/net/ipv6/conf/ovirtmgmt/disable_ipv6' | 
/usr/bin/at now+1 minutes
@reboot echo '/usr/sbin/route add default gw 192.168.1.254'  | 
/usr/bin/at now+1 minutes
