And this issue also happens on SLES12 Beta6 too. 1. Description a. Make Sure KVP is functional b. Leave VM running for several hours . After 7-10 hours KVP stop working and return NULL. 2. We also reproduced it on SLES12 Beta 6. On SLES12 Beta6 the KVP daemon stopped working after ~3 hours. hv_kvp_daemon service reported data, no other messages are recorded in the system log. hv_kvp_daemon.service - Hyper-V KVP Daemon Loaded: loaded (/usr/lib/systemd/system/hv_kvp_daemon.service; disabled) Active: inactive (dead) since Wed 2014-05-28 15:02:00 PDT; 8min ago Main PID: 494 (code=killed, signal=TERM) May 28 12:57:45 linux systemd[1]: Starting Hyper-V KVP Daemon...
