[ovirt-devel] [vdsm] what happens to ovirmgmt during new host deployment?

[Kai Kang]

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
