I'm able to run linux VMs on this server, and the network setup seems to be working for them (my main VM is running, and I also created a fresh debian VM just to test that). However it doesn't seem to be working for mirage unikernels... The unikernel starts, but just trying to ping it or connect to it (from the dom0) fails. I've attached the console log from the unikernel, the tcpdump log, and the log from the host. Interestingly, if I try to ping the unikernel, it seems to receive the ping packet, but doesn't reply. Would anyone have a clue? Cheers, and happy new year, Armaël [1] https://github.com/mirage/mirage-skeleton/blob/master/device-usage/network/unikernel.ml --------------87F9800183ABC2115F16CF76 Content-Type: text/x-log; name="dom0_console.log" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="dom0_console.log" # nc 10.0.42.20 2345 hello ^C # ping 10.0.42.20 PING 10.0.42.20 (10.0.42.20) 56(84) bytes of data. ^C --- 10.0.42.20 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6128ms --------------87F9800183ABC2115F16CF76 Content-Type: text/x-log; name="tcpdump.log" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="tcpdump.log" # tcpdump "port 2345" -i br0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br0, link-type EN10MB (Ethernet), capture size 262144 bytes 16:09:26.591790 IP 10.0.42.1.46212 > 10.0.42.20.2345: Flags [S], seq 3255497704, win 29200, options [mss 1460,sackOK,TS val 39448992 ecr 0,nop,wscale 7], length 0 16:09:27.612434 IP 10.0.42.1.46212 > 10.0.42.20.2345: Flags [S], seq 3255497704, win 29200, options [mss 1460,sackOK,TS val 39449248 ecr 0,nop,wscale 7], length 0 16:09:29.628449 IP 10.0.42.1.46212 > 10.0.42.20.2345: Flags [S], seq 3255497704, win 29200, options [mss 1460,sackOK,TS val 39449752 ecr 0,nop,wscale 7], length 0 16:09:33.884443 IP 10.0.42.1.46212 > 10.0.42.20.2345: Flags [S], seq 3255497704, win 29200, options [mss 1460,sackOK,TS val 39450816 ecr 0,nop,wscale 7], length 0 --------------87F9800183ABC2115F16CF76 Content-Type: text/x-log; name="unikernel_console.log" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="unikernel_console.log" # xl create network.xl -c Parsing config from network.xl MirageOS booting...

Hi Arma=C3=ABl,

I had a similar problem in the past and I solved by manually assigning in the .xl file a MAC address to the unikernel. As MAC addresses are pretty much randomized if you don't manually assign it, this might lead to problems in the ARP cache (different MAC same IP) as you start/stop the unikernel consecutively and, as Richard suggested, you might have to wait for ARP to sort it before the unikernel is properly reachable.

TL;DR: Try to assign a fixed MAC address to the unikernel in .xl file and see how it goes.

Best,
Vittorio

Hi everyone,

I'm trying to run the "network" unikernel (from mirage-skeleton [1]) on
my server, which uses Xen. I'm able to run linux VMs on this server, and
the network setup seems to be working for them (my main VM is running,
and I also created a fresh debian VM just to test that).
However it doesn't seem to be working for mirage unikernels...

The unikernel starts, but just trying to ping it or connect to it (from
the dom0) fails.

I've attached the console log from the unikernel, the tcpdump log, and
the log from the host.

Interestingly, if I try to ping the unikernel, it seems to receive the
ping packet, but doesn't reply.

Would anyone have a clue?

Cheers, and happy new year,
Arma=C3=ABl

I attached the log (with a xl list to see the mapping vm<->id). The vif interfaces do not seem to display any useful information in "ip a"; I'm not sure if that's normal or not.
