Consequently, Hyper-V is unable to obtain networking information about the VM (for example, IP addresses for vagrant, etc). Both `syslog` and `ls` indicate that the file is missing: root@dev-app:~# ls /dev/vmbus/ -l total 0 crw------- 1 root root 10, 55 May 2 00:11 hv_fcopy crw------- 1 root root 10, 54 May 2 00:11 hv_vss LSB Release Info: Description: Ubuntu 16.04.2 LTS Release: 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1687631/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
