Looking at the output of 'ifconfig' in a current Fedora 24 virtual machine, ens3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.122.161 netmask 255.255.255.0 broadcast 192.168.122.255 inet6 fe80::28d9:ec3:68f3:8791 prefixlen 64 scopeid 0x20<link> ether 52:54:00:48:0b:2a txqueuelen 1000 (Ethernet) RX packets 26834 bytes 22875114 (21.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 20369 bytes 2690889 (2.5 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 100426 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1 (Local Loopback) RX packets 24 bytes 1824 (1.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 24 bytes 1824 (1.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 192.168.124.1 netmask 255.255.255.0 broadcast 192.168.124.255 ether 00:00:00:00:00:00 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Note that the three leading bytes of the IPs of devices 'ens3' (192.168.122.x) and 'virbr0' (192.168.124.x) are different here, whereas under Fedora 25, they are identical (192.168.122.x). In a virtual machine running current Fedora 24, network connectivity is working correctly. After installing Fedora 25 on a virtual guest using the official live image Fedora-Workstation-Live-x86_64-25-1.3, the installed and updated systems still exibits working name resolution. Two differences compared to the earlier installation using F25-WORK-x86_64-20170202 appear related: (1) The output of 'ifconfig' in the current Fedora 25 virtual machine becomes ens3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.122.154 netmask 255.255.255.0 broadcast 192.168.122.255 inet6 fe80::a8be:85f0:ff64:e903 prefixlen 64 scopeid 0x20<link> ether 52:54:00:42:86:27 txqueuelen 1000 (Ethernet) RX packets 82 bytes 10957 (10.7 KiB) RX errors 0 dropped 13 overruns 0 frame 0 TX packets 105 bytes 10485 (10.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1 (Local Loopback) RX packets 24 bytes 1824 (1.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 24 bytes 1824 (1.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 192.168.124.1 netmask 255.255.255.0 broadcast 192.168.124.255 ether 52:54:00:45:90:38 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 which is equivalent to the situation under Fedora 24. (2) The network device using live image Fedora-Workstation-Live-x86_64-25-1.3 becomes Ethernet controller: Red Hat, Inc Virtio network device whereas using live image F25-WORK-x86_64-20170202, it was Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 20) For the latest live image F25-WORK-x86_64-20170210, things have gotten normal again. After installing Fedora 25 on a virtual machine using the latter and rebooting the system, 'ifconfig' returns: ens3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.122.8 netmask 255.255.255.0 broadcast 192.168.122.255 inet6 fe80::6c96:cdd6:38b6:b8ce prefixlen 64 scopeid 0x20<link> ether 52:54:00:b3:dc:e3 txqueuelen 1000 (Ethernet) RX packets 47 bytes 5764 (5.6 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 78 bytes 8635 (8.4 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 271 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1 (Local Loopback) RX packets 32 bytes 2352 (2.2 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 32 bytes 2352 (2.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 192.168.124.1 netmask 255.255.255.0 broadcast 192.168.124.255 ether 52:54:00:90:49:ce txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 |
