Just gave 3.0 a spin. Had been running 2.0.7 for the past 3 months or so without problems (aside from intermittent failure during live migration). Anyway, 3.0 seems to have an issue with my machine. It starts up the 4 domains that I''ve got defined (was running 6 user domains with 2.0.7, but two of those were running 2.4 kernels which I can''t seem to build with Xen 3.0 yet, and I see from the readme file it isn''t yet supported so I''m not complaining :-) Once the 4 user domains starts the machine will suddenly reboot. I added a sleep inbetween individual domain startups in xendomains and was able to get it to start up without rebooting, but then after about 5 or so minutes the machine rebooted again. I turned hyperthreading off on the machine and it seems to be able to boot with all 4 user domains just fine without the need for sleeps inbetween (very consistently dies if HT is enabled and I don''t sleep a little while between domain starts). So I''m leaving HT off for now to see if it remains stable with HT disabled. I was going to report this on bugzilla, but bugzilla.xensource.com is giving me a server error right now. -- Ray _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Done. Filed bug #432. Here is the information I entered into it for reference. Using pull from hg as of this morning (12/5/2005). If I enable hyperthreading on my machine then Xen gets into trouble within minutes of starting up user domains. With hyperthreading disabled it ran for several hours with no problem. Machine is a Dell Optplex GX280 with 2G of memory. I get the following on the screen when it hangs: [<c040acc0>] fn_hash_lookup+0xb0/0xc0 [<c03dba3b>] ip_route_input_slow+0x7cb/0x7e0 [<c0418f08>] br_nf_forward_finish+0xb8/0x140 [<c0413760>] br_forward_finish+0x0/0x70 [<c04192bc>] br_nf_forward_arp+0x17c/0x1c0 [<c013eed6>] buffered_rmqueue+0x106/0x250 [<c03cfb65>] neigh_update+0x235/0x350 [<c03c4214>] kfree_skbmem+0x24/0x30 [<c0400c11>] arp_process+0x61/0x510 [<c0414420>] br_handle_frame_finish+0x0/0x130 [<c04011b7>] arp_rcv+0xf7/0x170 [<c0410fa1>] packet_rcv_spkt+0x151/0x260 [<c03ca9a1>] netif_receive_skb+0x1e1/0x250 [<c012184e>] tasklet_action+0x4a/0xd0 [<c0121555>] __do_softirq+0x95/0xb0 [<c01215bd>] do_softirq+0x4b/0x50 [<c01215bd>] do_IRQ+0x22/0x30 [<c01048b0>] evtchn_do_upcall+0x70/0xa0 [<c0108c68>] hypervisor_callback+0x2c/0x34 [<c01068a2>] xen_idle+0x42/0x90 [<c0106933>] cpu_idle+0x43/0x50 [<c055e85d>] start_kernel+0x18d/0x1d0 [<c055e390>] unknown_bootoption+0x0/0x210 Kernel panic - not synching: BUG! -----Original Message----- From: Ian Pratt [mailto:m+Ian.Pratt@cl.cam.ac.uk] Sent: Monday, December 05, 2005 12:33 PM To: Cole, Ray; xen-users@lists.xensource.com Cc: ian.pratt@cl.cam.ac.uk Subject: RE: [Xen-users] Xen 3.0 and Hyperthreading an issue?> I turned hyperthreading off on the machine and it seems to be > able to boot with all 4 user domains just fine without the > need for sleeps inbetween (very consistently dies if HT is > enabled and I don''t sleep a little while between domain > starts).

I don''t have an appropriate cable for a serial console, but wouldn''t mind setting my console to 50 lines or something. But...how do I do that? I saw some references to adding ''vga=ext'' on the kernel command line to set it, but this doesn''t seem to actually do anything different when I boot. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
