The file gets copied up to the % in size and then hangs, it will never complete. Tested with one large file at a time, not simultaneous multiple files to transfer. Reproducible: Always Steps to Reproduce: 1.Login SLES SP3 and install hypervfcopyd 2. Enable "Guest services" integration services from hyperv manager 3. service hypervfcopyd start and make sure hypervfcopyd service is running 4. Login server 2012 R2 host and COPY-VMFILE large-file(larger than 1G) to guest 5. Check guest and host log Actual Results: Fcopy about %4 and hung up no log appear until display "timeout period expired" exception in host Expected Results: It should copy large file from host to guest correctly The fix is submitted to kernel community and accepted by Greg's tree. It will be in mainline soon. https://git.kernel.org/cgit/linux/kernel/git/gregkh/char-misc.git/commit/?h=char-misc-linus&id=affb1aff300ddee54df307812b38f166e8a865ef Could you please accept this patch in SLES release ASAP?

https://bugzilla.novell.com/show_bug.cgi?id=886840 https://bugzilla.novell.com/show_bug.cgi?id=886840#c3 --- Comment #3 from Kylie Liang 2014-07-22 08:02:33 UTC --- Sorry for confusion. 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.

https://bugzilla.novell.com/show_bug.cgi?id=886840 https://bugzilla.novell.com/show_bug.cgi?id=886840#c5 --- Comment #5 from Kylie Liang 2014-07-25 03:19:35 UTC --- Since https://bugzilla.novell.com/show_bug.cgi?id=887190 covers fcopy issue, I changed this bug title to "KVP stop working after several hours" to get focus on KVP issue on SLES 11 SP3. 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...
