[Xen-users] [SPAM] Massive UDP and TCP packet loss
Hi, I''m trying to get Xen running on 2 different systems and have massive packet losts independ from the system I use! This are the results from an UDP-Benchmark-Test from an Xen-Server to another one. As you make notice, the sending packets have a lost rate from > 80% up to 99%. What the hell is going on? I have no ideas. If I boot my 2 Xen-Servers with the normal kernel (without Xen) then all is running wonderfull and I have no packet lost! Therefore it must be a Xen problem! NETIO - Network Throughput Benchmark, Version 1.23 UDP connection established. Packet size 1k bytes: 11547 KByte/s (85%) Tx, 11460 KByte/s (0%) Rx. Packet size 2k bytes: 11031 KByte/s (92%) Tx, 11501 KByte/s (0%) Rx. Packet size 4k bytes: 9683 KByte/s (95%) Tx, 11677 KByte/s (0%) Rx. Packet size 8k bytes: 9459 KByte/s (96%) Tx, 11692 KByte/s (0%) Rx. Packet size 16k bytes: 5502 KByte/s (98%) Tx, 11694 KByte/s (0%) Rx. Packet size 32k bytes: 111 KByte/s (99%) Tx, 11716 KByte/s (0%) Rx _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
