[Users] oVirt 3.2 and Solaris 10 guests

Hi, I've a strange network issue with Solaris 10 x86 guests on oVirt 3.2 (beta) with an CentOS 6.3 hypervisor (using dreyou's repository for VDSM packages). My host configuration is the following: Operating system: Other Network interface type: rtl8139 Network Name: ovirtmgmt Disk interface: IDE Disk is working fine and the network interface is detected by Solaris 10 guest, as I can see a rtls0 interface with "ifconfig -a" and Solaris installer also detects this interface. But when I try to send packages over this interface they never reach a target - e.g. ping the gateway and "arp -an" doesn't show it's MAC address. On the hypervisor I can see vnet(x) interface is on ovirtmgmt bridge. Network traffic is working fine for all other VMs (RHEL 6 and Fedora 18) on ovirtmgmt bridge. Btw, when creating a Solaris 10 guest on RHEV 3.1 with RHEL 6.3 hypervisor the exactly same issue occurs - network interface is detected but no traffic passes this interface. On a plain KVM-Host (RHEL 6.3) I can create a Solaris 10 host with virt-manager using rtl8139 Virtual Network Interface Device model on a bridge (network setup is nearly the same as for oVirt and RHEV). On this RHEL 6.3 KVM-host network is working fine for Solaris guests. In the process list (ps -ef) the settings for oVirt and RHEL-KVM seem the be nearly the same (different fd's and option bootindex=3 is missing on KVM): oVirt 3.2: -netdev tap,fd=25,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:1a:4a:00:64:9e,bus=pci.0,addr=0x3,bootindex=3 RHEL 6.3 KVM: -netdev tap,fd=36,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:8e:3a:57,bus=pci.0,addr=0x3 KVM-Version is exactly the same on CentOS-oVirt-Hypervisor as on RHEL KVM-host: # rpm -qa | grep kvm qemu-kvm-rhev-tools-0.12.1.2-2.295.el6.10.x86_64 qemu-kvm-rhev-0.12.1.2-2.295.el6.10.x86_64 Do you have any clue why Solaris networking isn't working on oVirt but on RHEL-KVM it is? I didn't try Fedora 18 or oVirt Node as a hypervisor yet - don't think that there will be a difference. Thanks a lot for your feedback. -- Best Regards, René Koch
