RE: Re: Need help..

[Neugebauer, Rolf]

xc_dom_create.py should create the correct kernel command line for dom1.
In particular, it should pass the correct root partition to the domain
based. That is the "virtual partition", i.e., /dev/sda1 in your setup
from earlier today. The command line passed into the new domain should
be printed out by the newly started domain (and IIRC by xc_dom_create.py
as well)

You still have to have the correct entries in dom1's /etc/fstab (based
on the translation of physical partitions to 'virtual partitions' you
create). That's /dev/sda1 for / and /dev/sda6 for /usr of you still have
the same setup as you emailed earlier today.

What's the error message you get?

Re: Re: Need help..

[Mark Williamson]

Hi there,

> Warning: one or more hard disk extents are
>         writeable by two or more domains simultaneously.

1) You need to set /usr as read only in both fstabs, i.e.
in dom0:
LABEL=/usr	/usr	ext3	defaults,ro	1 2

in the other domain:
/dev/sda6	/usr	ext3	defaults,ro	1 2

Reboot dom0 so this change gets noticed.

2) Make sure you don't have /dev/hda8 mounted AT ALL in dom0 and make sure you 
don't mount it while the other domain is running.

That should fix you up.

Cheers,

Mark

Re: Re: Need help..

[I RATTAN]

I am confused:

dom0 /usr is /dev/hda6

and

dom1 /usr is /dev/sd6 which is mapped to /dev/hda7

does it mean even these are separate physical entities, they
have to mounted read-only?

if they are separate physical partitions mounting rw should be fine. We
normally just use one /usr partition and mount it ro to all domains.

to things to get closer to the root of your problem:

can you show us the output of 'mount' in dom0?

can you change the LABEL= entries in /etc/fstab to contain the /dev/hda*
partition names.

depending on how you created your partitions you might have multiple
partitions with the same label. I generally avoid using labels and use
the explicit devices.

Thanks

Re: Re: Need help..

[I RATTAN]

Ok, I replaced the LABEL=/ by /dev/hda5 and LABEL=/usr by /dev/hda6
in dom-0 /etc/fstaba. Now system does try to boot dom-1 but has prolems
with fsck of /dev/hda7 (/dev/sda6) and suggets to run fsck manually.
If fsck.ext3 is run from dom-0 on /dev/hda7 it says that file system is clean!
I plan to try /usr readonly tomorrow.

Here is the attempt with /usr (readolny) in both doma0 and dom-1
but have no success. Looks like boot script problem and I do not
have the expertise. Almost similar to separate /usr partitions.

problems with latest unstable

[Kip Macy]

I have a dual-processor Opteron 242 with 8GB of RAM running 32-bit
Fedora Core 1 (yes that means that 4GB is unused). I installed the
latest unstable on it last night.

I'm not sure what was happening because as currently configured it
doesn't print anything past:
(XEN) Device eth0 opened and ready for use.

'ping' indicated that it would come up for about 20 seconds and then
reboot. I enabled "debug ?= y" in Rules.mk and now it more or less
works :-O. One interesting thing that is probably worth noting is that
every time I type 'ls', I get the following on the console:

Scary.

What compiler are you using?

The lack of DOM0 output with the non debug build suggests that
Linux is dieing before its got the console subsystem up (which
happens annoyingly late in the init sequence. 

To get around this, I often add a
'HYPERVISOR_console_write(printk_buf, sizeof(printk_buf)' to
printk in kernel/printk.c

Hmm. This may suggest that Fedora has yet another sick and
twisted way of abusing segment registers for referencing thread
local storage for posix threads, and we're hitting an unexpected
(and probably slow) code path...

It might help to see an strace and an output of ldconfig -v, but
I suspect we'd need to recreate the setup to get anywhere.

gcc 3.3.2 - I just recompiled a non-debug xen with Fedora's stock gcc
instead of one that I had compiled. It works fine for the moment, but
I haven't been running it for very long.

I may just be passing the wrong parameter to grub, com1 is what is
mentioned in the HOWTO, that doesn't appear to be correct.

If futzing with the parameters doesn't work I'll do that.

Probably. Might "set_tid_address()" or "set_thread_area()" be the
offender?

execve("/bin/ls", ["ls"], [/* 42 vars */]) = 0
uname({sys="Linux", node="curly.lab.netapp.com", ...}) = 0
set_tid_address(0)                      = -1 ENOSYS (Function not implemented)
brk(0)                                  = 0x805a40e
<...>
set_thread_area({entry_number:-1 -> -1, base_addr:0x805a680,
limit:1048575, seg_32bit:1, contents:0, read_exec_only:0,
limit_in_pages:1, seg_not_present:0, useable:1}) = -1 ENOSYS (Function
not implemented)

If you're getting serial output from Xen, then the parameters on
the Xen command line must be OK. You should get console ouput
from xenolinux with console=xencons0

As I recall, these are in 2.6, but not 2.4 (unless you have a
redhat megapatch kernel).

libc decides at runtime which of the many thread local storage
schemes to use based on a wide range of inputs: kernel version,
syscall existence, cpu feature set, ldlibary cache, phase of the
moon, price of eggs, etc.

I expect it's using the one that involves the 'modify_ldt'
syscall, but might be using fs/gs in some new and exciting way
that we've yet to encounter on our systems...

Just a wild guess:

# mv /lib/tls /lib/tls-off

and reboot... If it's Thread Local Storage's fault that should stop 
happening :)

(But it's only a workaround...)

Try adding some tracing to do_console_io() in Xen. If the problem is
fixed by rebuilding Xen with debugging enabled then the problem is
almost certainly somewhere in that function. It's rather a small
function so it shouldn't be very hard to find.

If Xen's own output is going to the serial line then your options on
Xen's command line are correct. Xenolinux's command line should
contain 'console=xencons0'.

Nope, they're not supported in stock 2.4 kernels.

The fault is entirely harmless --- XL has switched LDT before
rewriting FS and GS. The old GS is no longer valid and so Xen can't
restore it. It gets pushed on XL's stack and a special handler in XL
gets called. This handler simply throws away GS and resets it to zero
(correct behaviour in this case because this is probably happening
during an exec(), when old execution state will be thrown away
anyway).

FYI:
The memory leak is gone. I can also cleanly shut down from within a
non-privileged domain - previously it would hang when trying to unmount
NFS partitions. However, 'xc_dom_control.py stop 3' still doesn't work.
I get an oops on the console of the domain 3 and networking is no longer
there.

Currently suspend/resume is simply not implemented:
 void blkdev_suspend(void)
 {
     /* XXX FIXME */
     BUG();
 }
 void blkdev_resume(void)
 {
     /* XXX FIXME */

scheduler panic

[Kip Macy]

FYI:
I reverted to 1.915 on the off-chance that the bug is a result of recent
scheduler changes not playing well on SMP. The machine is up and running
again.

Re: scheduler panic

[Kip Macy]

Mmmm - nope.

It is getting further, but it isn't making it up. I've pasted from the
point it made it to prior to your fix.

My previous offer still stands.

I think Keir's patch missed a further problem with the patch that's
causing the problem.

Please can you take the head before Keir's fix, then do a cset -x
on 1.916.1.1 ('Tweak to fix unblocking warping').

Or more correctly, by md5key:

'cset -x 40add516MWMX6XyHleHPhDU0Xn3ZHg'

Re: Re: scheduler panic

[Kip Macy]

Thanks.

That appears to work. One correction for anyone else out there who might
wish to do the same:
'bk cset -x40add516MWMX6XyHleHPhDU0Xn3ZHg'


Bitkeeper won't accept any spaces between -x and the argument. One thing
that makes it all the more annoying is that, although -x is documented
in the helptool, it isn't in the usage message:

kmacy@siml1 bk cset -x 40add516MWMX6XyHleHPhDU0Xn3ZHg
usage:  bk cset [-Cpq] [-i<list>] [-l ] [-M<range>] [-r<rev>]
