https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213618 Bug ID: 213618 Summary: When running as a Hyper-V Guest, FreeBSD 11 networking does not work Product: Base System Version: 11.0-RC1 Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: caesar@starkreality.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Host OS: Windows Server 2012 Guest OS: FreeBSD 11.0-RELEASE-p1 Neither the syntetic hnX NIC or the emulated Tulip deX NICs appear to be ab= le to transmit. The NICs are detected, and appear to be able to receive traff= ic (IPv6 SLAAC works, tcpdump shows broadcast/multicast traffic), but the NICs= are unable to transmit. dhclient complains send_packet: No buffer space availa= ble. After configuring a static address with ifconfig, attempts to send packets= via ping do not show up in a tcpdump. This has been verified under the followi= ng conditions: 10.3-RELEASE upgrade to 11.0-RELEASE 11.0-RELEASE fresh installation from .iso 11.0-RELEASE .vhd image from ftp.freebsd.org dmesg related to hn: hn0: <Hyper-V Network Interface> on vmbus0 hn0: LRO: entry count 128 hn0: unknown status 1073872902 received hn0: unknown status 1073872902 received hn0: hv send offload request succeeded hn0: 1 TX ring, 1 RX ring hn0: Ethernet address: 00:15:5d:xx:xx:xx hn0: TSO: 65517/31/4096 hn0: link state changed to UP ifconfig hn0 shows: hn0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3D71b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,TSO6,LRO> ether 00:15:5d:xx:xx:xx inet6 fe80::... prefixlen 64 scopeid 0x2 inet6 2601:... prefixlen 64 autoconf inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255 nd6 options=3D23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> media: Ethernet autoselect (10Gbase-T <full-duplex>) status: active --=20 You are receiving this mail because: You are on the CC list for the bug.=
