- Particulalry, does the host device with 10.0.100.42 sit on the same
bridge as your Solaris VM?

</BLOCKQUOTE>

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):<BR>

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

<BR>
<BR>
Yes, I can see them:<BR>
12:24:16.311218 ARP, Request who-has 10.0.100.42 (Broadcast) tell 10.0.100.123, length 46<BR>

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

- Have yout tried guest-to-guest communication (over the same bridge)?
</PRE>
</BLOCKQUOTE>
<BR>
I can communicate from the Debian 7 vm to all hosts in my network, but I can't reach the Solaris 11 vm.<BR>
The network of the oVirt setup is working fine for Windows and various Linux guests, but not for Solaris.<BR>
<BR>
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...<BR>
