Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Jiajun Xu (jiajun) Assigned to: Nobody/Anonymous (nobody) Summary: NFS copy makes guest network unstable Initial Comment: The NFS network of KVM guest is very unstable. When we copy a >600M file to the guest by NFS mount. The guest's network will down after finishing at about 500M size. Then, guest's network is down. Host also can not use "ping" or "scp". And sometimes, host also complains: ping: sendmsg: No buffer space available. I see memory by 'free', there is only 69MB free (While totally 8GB on the machine!). Using scp to copy file can not reproduce it. This issue is very easy to be reproduced (>50%). Reproduce steps: ---------------- 1. Create a guest and config NFS sharing folder on it 2. Mount the nfs folder to local folder --- /media 3. cp xxx /media 4. After some time, guest network is down ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2327497&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
