Hi all, I can confirm this bug, on latest openindiana-148 and qemu-kvm 0.13.0 you cannot even ping the virtualization host. With qemu-kvm-0.14.0 (just released!) you CAN ping the host: this is already an improvement. HOWEVER biggest bug is still there: if you log in to the openindiana machine via ssh and do "dmesg" or "netstat" or some other command which ouptuts a lot of text, the tcp socket will hang (well say it hangs once every 3 attempts) forever.
Going with tcpdump -e from within the guest, I have identified that the problem is when a big enough packet is outputed. I tried a few times with dmesg, and as soon as the tcp packet reaches the following length: 18:38:28.340097 52:54:69:b5:89:11 (oui Unknown) > 00:19:b9:81:2c:52 (oui Unknown), ethertype IPv4 (0x0800), length 1514: 192.168.7.38.ssh > 192.168.7.52.59008: Flags [.], ack 2824, win 64436, options [nop,nop,TS val 27488132 ecr 6063255], length 1448 it cannot get through. Then the IP stack tries and retries to send the same identical packet, but there will never be any reply from the other side. Finally the socket is torn down. I have bridged networking for the VM. My bridge is a normal linux bridge br0 with MTU 1500. Has MTU anything to do with all this? Is it a linux-bridge bug or a qemu-kvm bug? Please fix this, solaris is important for its ZFS.
