I think substantially I made your steps.

I take another test.
The host comes with also another adapter (em4) that is on vlan66
This is unconfigured in oVirt.
Then I create a new vlan named vlan66 with target vm
Then I run another virt-v2v of a vm named zensrv that is on vlan 66 from
qemu on CentOS 6.3 to oVirt

# time virt-v2v -o rhev -osd 10.4.4.59:/EXPORT --network vlan66 zensrv
zensrv_002: 100%

NOTE: actually the disk in oVirt after import is marked as VirtIO (as it
was on source) and boots without any problem....

Well, this vm is perfectly configured in its vlan and reachable as it was
on its original host.

After configuring this new vlan on host, this is the situation

and, from a bridge point of view

[g.cecchi at f18aio ~]$ sudo brctl show
bridge name bridge id STP enabled interfaces
;vdsmdummy; 8000.000000000000 no
ovirtmgmt 8000.001cc4ab3add no em3
vnet0
vlan66 8000.001cc4ab3ade no em4.66
vnet1

vnet0 is interface of c56cr that shoud be in vlan65
vnet1 is interface of zensrv that is correctly on vlan66

Please note that while on ovirtmgmt bridge there is em3 as physical
interface, on vlan66 there is em3... while I think it should be em3.65

Also, I noticed in similar configurations in Qemu+KVM on CentOS, that the
ip (10.4.4.59 in my case) should be on the bridge, if present.
So in my situation it should be on ovirtmgmt, while it is on em3.65.....

I could tweak configuration files in /etc/sysconf/network-scripts. Now they
are this way

ovirtmgmt/vlan65
[g.cecchi at f18aio network-scripts]$ cat ifcfg-em3.65
DEVICE=em3.65
ONBOOT=yes
VLAN=yes
NM_CONTROLLED=no
VLAN_ID=65
BOOTPROTO=none
IPADDR=10.4.4.59
NETMASK=255.255.255.0
GATEWAY=10.4.4.250
IPV6INIT=no

[g.cecchi at f18aio network-scripts]$ cat ifcfg-ovirtmgmt
DEVICE=ovirtmgmt
ONBOOT=yes
TYPE=Bridge
DELAY=0
NM_CONTROLLED=no
STP=no

vlan66

[g.cecchi at f18aio network-scripts]$ cat ifcfg-em4.66
DEVICE=em4.66
ONBOOT=yes
VLAN=yes
BRIDGE=vlan66
NM_CONTROLLED=no
STP=no

[g.cecchi at f18aio network-scripts]$ cat ifcfg-vlan66
DEVICE=vlan66
ONBOOT=yes
TYPE=Bridge
DELAY=0
NM_CONTROLLED=no
STP=no

My idea would be to modify the ovirtmgmt ones this way and reboot:

[g.cecchi at f18aio network-scripts]$ cat ifcfg-em3.65
DEVICE=em3.65
ONBOOT=yes
VLAN=yes
NM_CONTROLLED=no
BRIDGE=ovirtmgmt
STP=no

[g.cecchi at f18aio network-scripts]$ cat ifcfg-ovirtmgmt
DEVICE=ovirtmgmt
ONBOOT=yes
TYPE=Bridge
DELAY=0
NM_CONTROLLED=no
STP=no
IPADDR=10.4.4.59
NETMASK=255.255.255.0
GATEWAY=10.4.4.250

I don't know it there is any other initialization information in DB that
can cause problems....
