I have run into some weird situation wherein though I can ssh to the domU's (ltsp particularly) but when several users(8-10) have ssh sessions (ltsp in particular) it slows down almost coming to a grinding unresponsive halt. Only a xm shutdown ltsp or a restart seems to let me in again. So it is not that no packets go through to ltsp but then progressively seem to be dropped. But yet when I do a xentop I see that all packets are dropped. No firewall running on Dom0 and ltsp DomU. A firewall on daak DomU only which is acting as an internet gateway for ltsp as well. # xentop xentop - 17:38:50 Xen 3.3.1_18546_12-3.1 3 domains: 1 running, 2 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown Mem: 3141832k total, 3131412k used, 10420k free CPUs: 4 @ 2133MHz * * *NAME* *STATE* *CPU(sec)* *CPU(%)* *MEM(k)* *MEM(%)* *MAXMEM(k)* *MAXMEM(%)* *VCPUS* *NETS* *NETTX(k)* *NETRX(k)* *VBDS* *VBD_OO* *VBD_RD* *VBD_WR* *SSID* * * daak --b--- 9331 0.7 532348 16.9 532480 16.9 1 2 0 0 2 0 0 0 0 Net0 RX: 0bytes 0pkts 0err 23928drop TX: 0bytes 0pkts 0err 0drop Net1 RX: 0bytes 0pkts 0err 274084drop TX: 0bytes 0pkts 0err 0drop Domain-0 -----r 75748 3.1 618496 19.7 no limit n/a 4 0 0 0 0 0 0 0 0 ltsp --b--- 11071 0 1749884 55.7 1858560 59.2 2 2 0 0 1 0 0 0 0 Net0 RX: 0bytes 0pkts 0err 5255drop TX: 0bytes 0pkts 0err 0drop Net1 RX: 0bytes 0pkts 0err 27764drop TX: 0bytes 0pkts 0err 0drop Versions dom0 - Novell SLES 11 ltsp-domU - opensuse 11.1 xen 3.3.1 Do let me know if I can furnish any further info to help me debug this.
