To fix large file copy issue, above two patches are needed. In fact, the first patch is in drivers/hv/connection.c. Without it, KVP will stop working after several hours. What I want to check is whether SLES 11 SP3 could take the first fix (connection.c) to solve KVP issue. Should I open another bug or update title of this one for this KVP issue? Thank you. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But KVP will stop working after several hours. To fix this issue, two patches in connection.c, hv_util.c and hv_kvp.c are needed. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9... https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a...

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...
