Thanks a lot for your answer and sorry for my late response - I was sick
leaving last week.

# brctl show
bridge name	bridge id		STP enabled	interfaces
;vdsmdummy;		8000.000000000000	no		
dmz		8000.0025901ad140	no		eth0.200
ovirtmgmt		8000.0025901ad140	no		eth0.100
							vnet1
							vnet2
setup		8000.0025901ad140	no		eth0.500
test2		8000.0025901ad140	no		eth0.602
							vnet0

vnet1 is a Debian 7 vm which has a perfectly working network.
vnet2 is the Solaris 11 vm which can't communicate over the network.

10.0.100.42 is the ip of the oVirt host and it's ip is configured on
this bridge (and reachable from the Debian 7 vm):

# ip a | grep ovirt
5: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UNKNOWN 
    inet 10.0.100.42/24 brd 10.0.100.255 scope global ovirtmgmt

> - Do you see the who-has packet when sniffing the bridge device?

Yes, I can see them:
12:24:16.311218 ARP, Request who-has 10.0.100.42 (Broadcast) tell
10.0.100.123, length 46
12:24:16.311246 ARP, Reply 10.0.100.42 is-at 00:25:90:1a:d1:40, length
28

I can also see the MAC of the Solaris vm in arp cache of oVirt host:
# arp -an
? (10.0.100.123) at 00:99:4a:00:64:83 [ether] on ovirtmgmt

But I can't see the MAC address of oVirt host (10.0.100.42) in arp table
of the Solaris 11 vm. To be more clear: I can't see any MAC address in
ARP table of Solaris vm except the MAC of the vm itself.

I can communicate from the Debian 7 vm to all hosts in my network, but I
can't reach the Solaris 11 vm.
The network of the oVirt setup is working fine for Windows and various
Linux guests, but not for Solaris.

Btw, excatly same behavior on RHEV 3.2 with Solaris 10/11 - Windows and
Linux is working as expected, but no networking for Solaris guests...
