This however must not affect the pinging of link-local addresses ON the virtual machine: ping -I <eth0> <link-local of server> must work. If not check both side link-local addresses if they are set. A quick way to check with "any-body on the segment please reply" is to on virtual machine ping6 -I <eth0> ff02::1 You must see 2 addresses (one is your own link-local and the other is the address on the server) Example in my case is pasted (there are 4 machines): $ ping6 -I n1 ff02::1 PING ff02::1(ff02::1) from fe80::2c3b:53ff:fea0:9d26 n1: 56 data bytes 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=1 ttl=64 time=0.099 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=1 ttl=64 time=0.590 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=1 ttl=64 time=0.967 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=1 ttl=64 time=2.10 ms (DUP!) 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=2 ttl=64 time=0.097 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=2 ttl=64 time=0.318 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=2 ttl=64 time=0.701 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=2 ttl=64 time=1.06 ms (DUP!) ^C --- ff02::1 ping statistics --- 2 packets transmitted, 2 received, +6 duplicates, 0% packet loss, time 1001ms If link-local address cannot be ping-ed then try pinging ::1. _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
