Thank you Kai for describing you solution!

However, I think the ovirtmgmt network should be created automatically. 
I will forward this issue on.

Cheers, Ondra

 Hi Ondra,

 Thanks for your patience with my so many questions.

 Finally I search a Redhat defect 
 https://bugzilla.redhat.com/show_bug.cgi?id=1222566, and it seems 
 caused by lacking of libvirt network "vdsm-ovirtmgmt". After I create 
 the network by hook, then the host could be deployed successfully.

 Hook files under /usr/lib64/vdsm/vdsm/hooks/before_vdsm_start:

 vdsm-ovirtmgmt.xml:
 <network>
         <name>vdsm-ovirtmgmt</name>
         <forward mode='bridge'/>
         <bridge name='ovirtmgmt'/>
 </network>

 20-setupDefaultNetwork:
 #!/bin/sh

 VIRSH=/usr/bin/virsh
 SOURCEDIR=$(dirname $(readlink -f $0))
 DEFAULTNET=vdsm-ovirtmgmt

 if ! $VIRSH net-dumpxml $DEFAULTNET &>/dev/null; then
         $VIRSH net-define $SOURCEDIR/vdsm-ovirtmgmt.xml
 fi

 Regards,
 Kai

     Kai,

     please also take a look at /var/log/ovirt-engine/engine.log

     VDSM stores the engine's request for capabilities in vdsm.log, and
     logs Setup Networks actions in supervdsm.log.

     I'll inspect logs you sent me privately. Can you please make the
     engine logs available to the list?

     Thanks,
     Ondra
