KVP daemon crashes after approximatively 2 minutes of uptime and it enters in a failed state. The daemon can be manually started and it enters back in active (running) state. The error messages from /var/log/syslog after the daemon enters the failed state are the following: Apr 25 04:28:46 bionicDaily KVP: read failed; error:9 Bad file descriptor Apr 25 04:28:46 bionicDaily systemd[1]: hv-kvp-daemon.service: Main process exited, code=exited, status=1/FAILURE Apr 25 04:28:46 bionicDaily systemd[1]: hv-kvp-daemon.service: Failed with result 'exit-code'. Apr 25 04:28:59 bionicDaily systemd[1]: Started Hyper-V KVP Protocol Daemon. Note: There was a simmilar issue discussed on this thread https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664663, but the fixing commit seems to be inclued in this Bionic build. 2. After the KVP daemon is being started the following messages appear: Apr 25 04:45:25 bionicDaily hv_kvp_daemon[1895]: sh: 1: /usr/libexec/hypervkvpd/hv_get_dns_info: not found Apr 25 04:45:25 bionicDaily hv_kvp_daemon[1895]: sh: 1: /usr/libexec/hypervkvpd/hv_get_dhcp_info: not found The above binaries are present on the system, but the their actual path is /usr/sbin/hv_get_dns_info and /usr/sbin/hv_get_dhcp_info. Either the hv_get_dhcp_info and hv_get_dns_info binaries should be placed in the location where the daemon is looking for (/usr/libexec/hypervkvpd/), or the daemon should be set to search for the binaries in the /usr/sbin directory.
