[Xen-devel] Xen-Unstable : strange power cycling problem
Hi, Today I tried Xen Unstable again, using latest version from bk repository. Xend starts without any problem and I was able to start the new domain easily. I can ssh to new domain and everything works as expected. That''s great! But if I do a ssh (or try any sort of network connection) to domain0, it just power cycles the machine. I am able to ssh to other machines though. Seems something strange happening in network virtualization.. sachin __________________________________ Do you Yahoo!? Yahoo!

Would it be possible for you to connect a serial console to collect a crash dump? You''ll need to put "com1=115200,8n1" on the xen grub line. Because dom0 owns the VGA console, Xen isn''t easily able to do a crash dump to it. Hmm, maybe Xen should try snatching it back in the event of a crash, but this wouldn''t work if the display was running X anyhow. Is your machine multiprocessor? If so, can you reproduce with "nosmp" on the Xen command line? It seems rather more likely that you''re experiencing a general networking problem rather than something specific to incoming connections. Please can you test this by trying to exercise networking e.g. using ttcp. Although it won''t help with this particular problem, its always worth running with "watchdog" enabled.

hi there,
I used to use xen 1.2,and it worked fine. Now I wanna to try out the xen gdb
debug stub, so switched to xen-unstable.
I just ''make world'' and ''make install'',
according to the README.And the grub
configure is like:
title Xen_1.3 / XenoLinux_1.3 2.4.26
kernel /xen.gz dom0_mem=131072 com1=115200 8n1 noht
module /vmlinuz-2.4.26-xen0 root=/dev/hda5 ro concole=tty0 3
But when booting up, it doesn''t have network connection. Only has
localhost
domain name and 127.0.0.1 address.
Where did I do wrong?
Thanks,
Yan

It''s possible that the default dom0 config currently doesn''t include it, though we tried to include most popular cards. You can enable it in the normal way by going into linux-2.4.26-xen0 and editing .config and then doing a "make dep" "make dist".

Re: [Xen-devel] Xen-Unstable : strange power cycling problem
No error message, machine simply reboots. By sshing to other machines, I mean from dom1. I am able to ssh to other machines from domain 1, but if try ssh to dom0, this reboot happens. And it''s not just ssh, if I try any network connection to dom0 from dom1, machine just reboots. sachin Do you get any error messages or a crash dump, or does the machine simply spontaneously reboot?

Re: [Xen-devel] Xen-Unstable : strange power cycling problem
I will try to get a serial console setup on Monday to collect crash dump. Will it dump it by default on serial console before rebooting though? No SMP, it''s a single processor machine. BTW, I had mentioned watchdog in grub boot line, when it happened (though i am not sure where watchdog is supposed to log?) No, it''s not a generic networking problem.. it comes only when I try to connect to dom0 from dom1. Other cases like, connecting to another machine from dom1, and conencting to dom1 from other machine works fine. I will try connecting to dom1 from dom0 and see what happens. Do you guys get similar problem on your systems, or is it just me.. sachin Ian Pratt <Ian.Pratt@cl.cam.ac.uk> wrote: This is obviously very concerning.

> I will try to get a serial console setup on Monday to collect crash dump. Will it dump it by default on serial console before rebooting though?If you configure the Xen serial console "com1=115200,8n1" you should get a crash dump. There are some very rare circumstances where this doesn''t happen, but I suspect that you''ll get an Oops from domain 0, then Xen saying "domain 0 exited, rebooting machine". Hopefully the crash dump will tell us why dom0 exited. BTW: Are you using one of our pre-compiled xen and xenlinux images? We''ll need the vmlinux-syms file to interpret the crash dump.> No SMP, it''s a single processor machine. BTW, I had mentioned watchdog in grub boot line, when it happened (though i am not sure where watchdog is supposed to log?)The watchdog will detect and generate a crash dump if certain types of deadlock occur. It''s unlikely to help debug this particular problem.> Do you guys get similar problem on your systems, or is it just me..I''ve just ssh''ed into dom0 for dom1 just fine. I haven''t seen a bug for quite sometime, and I''ve been thrashing the system pretty hard.

yeah, I found the typo in the grub.conf. But actually I just used it with
1.2, and worked fine.
I''ll change it anyway.
I checked the ethernet card is e100, which is not set in .config, so just
set ''CONFIG_E100=y'',right?
but I have question about ''make dep'' and ''make
dist''. It''s done under
/xeno-unstable.bk, not under
/xeno-unstable.bk/linux-2.4.26-xen,right? But after I did it, it still
doesn''t work.
I found ''make dist'' only build xen and tools, didn''t
use .config,so I guess
the change isn''t effective.
And with ''make world'', it change back to the original .config,
so no use
either.
So I guess maybe I should try set ''CONFIG_E100=y'' in .config,
and
make linux_xenU_config
make linux_xenU
make linux_xen0_config
make linux_xen0
Is the guess right?
Sorry for your time, coz I''m working remote now, if screw it again,
then I
cannot login. So better make sure how to deal it.
Thanks,
Yan

Doing the same from dom0 to dom1 works fine, as does going from dom1 to an external machine. What''s surprising is that I can run both a tcp and udp blaster in both directions between dom0 and dom1 without triggering the bug. It must be something specific to incoming connections, which is quite a surprise as there should be nothing xen specific about this. I wander if we''re provoking a latent linux bug? Now we can reproduce it should be possible to work out what''s going on... Ian ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.

hi, I tried both, first: make -j4 world cd linux-2.4.26-xen vi .config ARCH=xen make dep cd .. make install second vi install/boot/config-2.4.26-xen0 make linux_xenU_config make linux_xenU make linux_xen0_config make linux_xen0 cp install/boot/vm* /boot but both didn''t work. :( although it did change the .config in the second try.

ok, now it works. I found you set e100 enabled in defconfig-xen0. So I just
cloned it again and build it all over again, and it works fine. Thank your
help.
btw, I have a question about how xen handle the system calls. Xen has fast
trap mechanism. But when we commented out the line
"HYPERVISOR_set_fast_trap(SYSCALL_VECTOR);"
in xenolinux-2.4.26/arch/xeno/kernel/traps.c, (talking about 1.2 here)
xen still performed well. So xen must have something to handle system calls
from guest OS, right? but we cannot find where it did this. It seems to us
xen only defined 0-19, not 128 for system calls.
Thanks,
Yan

Xen detects that type of error code and, if the guest OS registered a suitable virtual handler on that vector, virtualises the GPF as a trap of the appropriate type. If teh guest OS didn''t, then the GPF is virtualised as a GPF in the usual way.

Re: [Xen-devel] Xen-Unstable : strange power cycling problem
I was making use of a ''protocol private'' part of the per-packet ''skbuff'' structure to store some useful info. Comments in Linux seemed to indocate that whoever currently had the skbuff queued could safely use this area. This is actually untrue (at least for net devices, which admittedly isn''t protocol code :-) ). Just so happened that for certain packet types and timings we''d overwrite TCP info in that area which caused havoc. -- Keir> Great !! > > So what was causing this bug? > > sachin > > Keir Fraser <Keir.Fraser@cl.cam.ac.uk> wrote: > > This domain-crashing bug should now be fixed in the unstable > repository.

unfortunaly new problems comes. :(
I noticed long ago that after install xen, ''halt''
didn''t work, it just acted
like reboot. So I wanna try it on this 1.3, and it turned that it still just
reboots the machine. And I trid this on two xen machines, both worked this
way.
More serious problems is after this reboot, eth0 lost again. I didn''t
change
anything since eth0 was up. I''m sure the .config has set e100=y. So I
''make
clean'' and ''make world'' ''make
install'' again, still didn''t work.
Then I add printk("hello world from e100_init_module\n") in
e100_main.c. and
then just ''make linux-xen0'', ''cp
/install/boot/vmlinuz-2.4.26-xen0''. From
dmesg, can see this:
e100:selftest timeout
e100:failed to initialize, instance #0
hello world from e100_init_module
While if I use just reboot to standard linux or xen 1.2, eth0 works fine.
Then I changed the grub, use 1.2 kernal+1.3 module, it shows that e100
selftest ok, eth0 is ready, but surely invalid guest OS image. I also tried
1.3 kernal+1.2 module, just didn''t go to e100 step. My question here is
when
useing 1.2 kernal+1.3 module, why the ''hello world from
e100_init_module''
didn''t appear?
After these two tries, I changed the grub back to normal 1.3 kernal+1.3
module, and, it magically worked, eth0 is back again.
Then I rebooted again to see what''d happend, and again, eth0 was lost.
same
as the info above. And I tried all these stuff again, still no eth0.But
still, if I loaded into linux or xen 1.2, it''s fine, so it seems not
network
card''s problem. And also with another machine, all works well.
It''s network
card driver is not e100 though, it''s 3c59x.
Anyone can help? I was rebooting like crazy, really frustrated. :(
Thanks,
Yan

I think invoking halt/reboot in other domains does the right thing, though I haven''t checked (there''s at least now code for a domain to exit with a code indicating what action it wants). Whenever domain 0 exits, Xen reboots the machine. I guess we could look at the exit code and loop if its a halt.> More serious problems is after this reboot, eth0 lost again.

I''m guessing Xen does a soft reboot when it exits, as its faster and works on the vast majority of hardware. I guess we could add a "hardreboot" xen cmdline option, but rebooting a PC in s/w is a bit of a black art.

Can you increase the timeout in e100_selftest, or check the return value from schedule_timeout (it maybe returnign early), or perhaps try calling e100_selftest a few time before failing? -- Keir ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.

[Xen-devel] Xen, gridcluster, boot with red hat ent 3
Hi, thanks for the answers, they will be important for this project and hopefully Xen can be usefull for the beta-oriented gridcluster. The only problem right now is to make it boot up with a distribution (Cern Linux) based on the Redhat Ent 3. I follow all the instructions, there should be no HW conflicts , but still the bootup halts on "Freeing kernel mem.." The Xen boots up perfectly with Debian Sid.. The Red Hat Ent 3 is pretty old, but the glibc is compiled for i686 and the Xen kernel is compiled for the the right cpu, so the traditional error are checked out. The system is not halting either, but seems to go in an eternal loop. The keyboard works, but I cannot ping or ssh the OS.. I have tried the sysreq option, where sysreq p gives: PID: 1, comm init EIP: 0819[<00ae870>] CPU: 0 EFLAGS: 00201217 Not tainted the last Bootlines gives: hdc: attached ude-cdrom driver hdc: ATAPO 48X DVD-ROM drive, 512kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.12 Partition check: hda: [PTBL] [4865/255/63] hda1 hda2 hda3 SCSI subsystem driver Revision: 1.00 Red Hat/Adaptec aacraid driver (1.1-3 Jul 1 2004 14:08:39) megaraid: v1.18k megaraid: no BIOS enabled scsi0 : SCSI host adapter emulation for IDE ATAPI devices Initialiising Xen netif backend NET4: Linux TCP/IP 1.0 for NET4.0 IP Protocols: ICMP, UDP, TCP IP: routing cache hash table of 1024 buckets, 8Kbytes TCP: Hash tables configured (established 8192 bind 16384) ip_conntrack version 2.1 (1024 buckets, 8192 max) - 288 bytes per conntrack ip_tables: (C) 2000-2002 Netfilter core team NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.

You need "com1=115200,8n1" on the Xen grub line and "console=ttyS0" on the xenlinux command line. Can you post the grub config and all the serial output.

Clutching at straws, it might be worth comparing the major/minor number of /dev/console between RH3 and Debian Sid. I seem to recall it changed from 4 to 5 at some point. Also, what happens if you have "console=ttyS0 console=tty0" (or vice versa) on the xenlinux command line. Have you modified your /etc/inittab and to start a getty on /dev/ttyS0? (you''ll probably need to ad ttyS0 to /etc/securetty too). At least you should be able to login in and prod around even if you haven''t solved the console output problem.
