Hi,
Network performance on MirageOS Solo5/ukvm is not optimized yet, but you can try bridged networking by the following:
(I guess you have a bridge device "virbr0" created by libvirt) ip tuntap add tt0 mode tap ip link set dev tt0 up brctl addif virbr0 tt0 sudo ./ukvm-bin --net=tt0 iperf_server.ukvm
Kind regards
-- Takayuki Imada HiI just tried to compile MirageOS, and wanted to test networking performance, to compare regular linux/ubuntu KVM VM vs. mirageOS:Linux VM has IP 192.168.122.20:ping 192.168.122.20PING 192.168.122.20 (192.168.122.20) 56(84) bytes of data.64 bytes from 192.168.122.20: icmp_seq=1 ttl=64 time=0.114 ms...20 packets transmitted, 20 received, 0% packet loss, time 19434msrtt min/avg/max/mdev = 0.116/0.157/0.193/0.027 msmirage VM has IP 192.168.122.100.ping 192.168.122.100PING 192.168.122.100 (192.168.122.100) 56(84) bytes of data.64 bytes from 192.168.122.100: icmp_seq=1 ttl=38 time=0.090 ms...20 packets transmitted, 20 received, 0% packet loss, time 19490msrtt min/avg/max/mdev = 0.087/0.119/0.169/0.021 msSo here mirage has lower latency, nice :)But with iperf server on VM, and client on host:(mirage iperf is from https://github.com/TImada/mirage_iperf)ubuntu VM:iperf -c 192.168.122.20 -t10------------------------------------------------------------Client connecting to 192.168.122.20, TCP port 5001TCP window size: 85.0 KByte (default)------------------------------------------------------------[ 3] local 192.168.122.1 port 52674 connected with 192.168.122.20 port 5001[ ID] Interval Transfer Bandwidth[ 3] 0.0-10.0 sec 52.9 GBytes 45.4 Gbits/sectop: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4401 qemu 20 0 6038648 2.309g 22968 S 100.0 7.4 43:24.27 qemu-system-x86 4422 root 20 0 0 0 0 R 83.2 0.0 0:22.90 vhost-4401 24759 justin_+ 20 0 165812 1892 1728 S 51.5 0.0 0:03.91 iperfmirage VM:sudo ./ukvm-bin --net=tt0 iperf_server.ukvmjustin_cinkelj@jcpc:~/devel/orange$ iperf -c 192.168.122.100 -t10------------------------------------------------------------Client connecting to 192.168.122.100, TCP port 5001TCP window size: 85.0 KByte (default)------------------------------------------------------------[ 3] local 192.168.122.101 port 44920 connected with 192.168.122.100 port 5001[ ID] Interval Transfer Bandwidth[ 3] 0.0-10.0 sec 2.80 GBytes 2.40 Gbits/sectop: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24788 root 20 0 528708 16148 16064 R 100.0 0.0 0:04.35 ukvm-binNow, I guess I'm doing something wrong. I would try bridged networking with mirage, but I don't know how.What else could/should I change?BTW, the tt0 network device was created with:tunctl -t tt0ip link set up dev tt0ip addr add 192.168.122.101/26 dev tt0Justin_______________________________________________MirageOS-devel mailing listMirageOS-devel@xxxxxxxxxxxxxxxxxxxxhttps://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel
