tap:qcow causes dom-U to hang in 3.0.3

tap:qcow causes dom-U to hang in 3.0.3

[Roland Paterson-Jones]

Hi all

I have had some success with the new blktap support in Xen 3.0.3. In 
particular, the loopback drop-in, tap:aio: works somewhat reliably.

However, I am really interested in copy-on-write support, and hence have 
been trying tap:qcow:. This has had limited success, in that dom-U's 
appear to launch. However, as soon as I try to console or ssh into the 
dom-U's they apparently freeze, and I can get no further with them.

I have managed to 'xm terminate' the frozen dom-U's, but this leaves 
xend in some inconsistent state. All further 'xm xxx' commands barf with 
the following error:

[root@dom0]# xm list
Error: Device 2050 not connected
Usage: xm list [options] [Domain, ...]

Curiously, it seems that device 2050 was a secondary block device 
exposed using phy:.

So, any advice on how to debug this?

Thanks and kind regards
Roland

Could we see your /var/log/xen/*  and the output of xenstore-ls?

Thanks,

Logs attached. xenstore-ls below.

I had two domains running. One with root-fs using 
tap:aio:/mnt/instance_image_store_1/3811, and a second dom-U on 
tap:qcow:/mnt/instance_image_store_0/3811.qcow, which was set up as a 
COW overlay of image file /mnt/instance_image_store_0/3811 (not the same 
as the tap:aio: image for the first domU - the directories differ in 
their last digit). 

Then both dom-U's also had/have a swap partition (vbd phy:) on 
/dev/VolGroupDomU/instance_swap_store_1/0 and a second vbd phy: on 
/dev/VolGroupDomU/instance_ephemeral_store_1/0.

The 'xenstore-ls' also shows qcow:/mnt/instance_image_store_2/3811.qcow 
which I don't think should be there at all (maybe from a previous failed 
attempt).

Could this be related to tap:qcow: mounts not umounting? I previously 
set up a test tap:qcow: device in dom0 using 'block-attach 0 ...', then 
mounted it, which seemed to work OK. However 'umount ...' then hung 
(seemingly in the kernel - I had to reboot to get rid of it).

Thx Roland

Not sure this got through first time round - I got 'quarantine' messages 
about the .tgz attachment. Attached here uncompressed (!)

Logs attached. xenstore-ls below.

I had two domains running. One with root-fs using 
tap:aio:/mnt/instance_image_store_1/3811, and a second dom-U on 
tap:qcow:/mnt/instance_image_store_0/3811.qcow, which was set up as a 
COW overlay of image file /mnt/instance_image_store_0/3811 (not the same 
as the tap:aio: image for the first domU - the directories differ in 
their last digit).
Then both dom-U's also had/have a swap partition (vbd phy:) on 
/dev/VolGroupDomU/instance_swap_store_1/0 and a second vbd phy: on 
/dev/VolGroupDomU/instance_ephemeral_store_1/0.

The 'xenstore-ls' also shows qcow:/mnt/instance_image_store_2/3811.qcow 
which I don't think should be there at all (maybe from a previous failed 
attempt).

Could this be related to tap:qcow: mounts not umounting? I previously 
set up a test tap:qcow: device in dom0 using 'block-attach 0 ...', then 
mounted it, which seemed to work OK. However 'umount ...' then hung 
(seemingly in the kernel - I had to reboot to get rid of it).

Re: [Xen-users] Re: tap:qcow causes dom-U to hang in 3.0.3

I suspect this part of the xenstore-ls may be significant:

   error = ""
    backend = ""
     tap = ""
      1 = ""
       2049 = ""
        error = "2 getting info"

Is there somewhere I can get more info on the cause of the error? Also, 
given that the error seems 'sticky', in that 'xm shutdown' and 'xm 
destroy' don't appear to be able to get rid of the tap device, how do I 
identify where the tapdisk (or whatever) process is stuck?

Thanks for any advice
Regards
Roland

I think that this might be misleading.  This error will be recorded when the
frontend comes up if the backend isn't yet ready, but once the backend becomes
ready, the frontend should retry.  It looks like that retry has been
successful (everything is in state 4 == Connected) so the error message is
bogus (we should actually delete that error when the connection completes
successfully).

I don't see any other smoking gun in your logs, I'm afraid, and I'm out of
ideas.  I'll see if we can repro this.

Ewan.

I'm seeing (what I believe to be) the same thing, so here's some more data
points. This is Xen 3.0.3, compiled from the source.tgz, dom0 is Ubuntu 6.06,
domU is Debian Sarge. The error occurs when using a file-backed qcow-image,
using a standalone qcow image or tap:aio works just fine.

# qcow-create 1024 vm01.qcow vm01.img
# cat sample.xen
name="vm01"
kernel="/boot/vmlinuz-2.6-xen0"
ramdisk="/boot/initrd.img-2.6.16.29-xen0"

dhcp="off"
# xm create sample.xen -c
(boots up to login prompt, but freezes after entering the username)
# xm destroy vm01
# xm list
Error: Device 769 not connected

>From then on I haven't been able to un-wedge Xen other than by rebooting the
machine.

Please let me know if there's anything I can do to help debug this.

Re: [Xen-users] Re: tap:qcow causes dom-U to hang in 3.0.3

[Julian Chesterfield]

Roland,

Can you also verify whether there's an active tapdisk process running 
in Dom0 for each tap:{aio,qcow} vbd. We are aware of a bug with the 
qcow implementation that we hope to submit a fix for very soon. It's 
likely that you are seeing the same issue.

- Julian

Sorry, this is not what you asked for, but this is what an 'ls' of the  
qcow file shows:

 [root@dom0-0-50-45-5d-6a-bc ~]# ls -als /mnt/instance_image_store_0/
total 1564108
      4 drwxr-xr-x  2 root root          4096 Nov 10 15:42 .
      8 drwxr-xr-x  8 root root          4096 Nov  7 17:56 ..
1563132 -rw-r--r--  1 root root    1599078400 Nov 10 15:42 2
    964 -rw-r--r--  1 root root 1099645846016 Nov 10 15:50 2.qcow

It looks like the qcow file has grown to > 1000GB in (apparent) size(!) 
Could this be the root of the problem?

At this stage the dom-U is still running, but the qcow file is clearly 
not right. The file called '2' is a loopback image backing the qcow file.

The qcow overlay was created using '/usr/sbin/qcow-create $((10*1024)) 
/mnt/instance_image_store_0/2.qcow /mnt/instance_image_store_0/2'. I'm 
guessing there's no danger in making the qcow overlay extent (10GB) 
larger than the underlying loopback file extend (1.5GB) but please 
correct me if I'm wrong.

Earlier, an ls of the same directory (soon after dom-U creation) looked 
like:

[root@dom0-0-50-45-5d-6a-bc ~]# ls -als /mnt/instance_image_store_0/
total 1564052
      4 drwxr-xr-x  2 root root       4096 Nov 10 15:42 .
      8 drwxr-xr-x  8 root root       4096 Nov  7 17:56 ..
1563132 -rw-r--r--  1 root root 1599078400 Nov 10 15:42 2
    908 -rw-r--r--  1 root root     925696 Nov 10 15:43 2.qcow

Could this be the root of the problem - i.e. something in the qcow 
driver is getting it's offsets in the qcow file mangled?

Can I try to compile the qcow (tapdisk) driver with debug enabled? Where 
would the output go?

Roland

To answer your question, yes, it does appear that a tapdisk process is 
still running (this is after the dom-U has hung):

[root@dom0-0-50-45-5d-6a-bc ~]# ps -aef | grep tapdisk
root      4135     1  0 15:42 ?        00:00:01 tapdisk 
/dev/xen/tapctrlwrite1 /dev/xen/tapctrlread1

There is only one tap device, and the pid is the same as the single 
candidate while the dom-U was still reachable.

The hand seems to occur on the first (significant?) disk write inside 
the dom-U. For example:

-bash-3.00# dd if=/dev/zero of=./test-10MB bs=1k count=$((10*1024))

Has hung the dom-U, and I can no longer console or ssh into the dom-U.

Interestingly, on the dom-U, the qcow file has shrunk from its pervious 
peak of > 1TB, and is now appearing modestly as:

It's all very confusing. I'd love it to work, of course. Let me know 
what I can do to help with a diagnosis.

I'm running on the (binary) PAE-enabled 3.0.3 release.

Thanks and kind regards

Hmm, this shoudn't happen. Looks like the block offset lookup is 
screwed up.

So the current overlay support actually ignores the size value and 
creates a sparse overlay file with the same virtual size as the 
original. Technically it would be possible to create an overlay file 
larger than the source and fault read/writes for larger block offsets 
to the overlay disk, however I'm not certain this is a good idea.

There's a bunch of DPRINTFs in the code which send debug output to 
syslog. You can play with syslog settings to switch on the debug 
messages and direct them to a log file.

Thanks for the file size tip, I'll explore further.

Here is another clue from syslog. Below is the full log, but the hang 
seems to accur when the following log messages are triggered (there's a 
bunch of them at the end):

Nov 14 11:59:47 dom0-0-50-45-5d-6a-bc TAPDISK: AIO_LOCK or 
iocb_free_count (0) failed[869040]

I'm a little frustrated with re-building the blktap user-space tools 
myself. When I do so, I get the following kernel messages:

Nov 13 13:44:08 dom0-0-50-45-5d-6a-bc kernel: blk_tap: invalid user 
buffer -- could not remap it
Nov 13 13:44:08 dom0-0-50-45-5d-6a-bc kernel: blk_tap: Reached Fail_flush
Nov 13 13:44:08 dom0-0-50-45-5d-6a-bc kernel: blk_tap: BLKTAP_INVALID_HANDLE

But I don't get these when I use the (PAE) binary distribution. I'm only 
rebuilding the blktap tools, not the rest, so perhaps my config is not 
right (incompatible with the PAE kernel somehow). If you know off-hand 
what the problem is then I can maybe chase down the offset issue more 
productively.

And when I try to 'xm destroy' the instance after it hangs, I get a slew 
of the following :

Nov 14 12:41:35 dom0-0-50-45-5d-6a-bc kernel: blk_tap: invalid kernel 
buffer -- could not remap it
Nov 14 12:41:35 dom0-0-50-45-5d-6a-bc kernel: blk_tap: Reached Fail_flush
Nov 14 12:41:35 dom0-0-50-45-5d-6a-bc kernel: blk_tap: BLKTAP_INVALID_HANDLE

This is the inverse of the error messages I see when I build the 
user-land tools myself. In the above it's the kernel buffer that can't 
be re-mapped. With my user-land tools it's the user buffer that can't be 
remapped. I wonder (but have no idea) whether this is related to PAE at all.

tap:qcow causes dom-U to hang in 3.0.4-rc1

[Hiromichi Itou]

Hi,

This problem had been discussed on this ML before.
Please refer to following URL.
	http://lists.xensource.com/archives/html/xen-devel/2006-11/ 
msg00391.html

This problem still remains in Xen 3.0.4-rc1.　(I tested on  
x86-64.)

Steps to Reproduce:

1) Create bootable DomainU image.
	dd if=/dev/zero of=/var/images/storage.disk1.sys1 bs=1024k count=1  
seek=8191
	  etc.

2) Create qcow file that has backing file.
	qcow-create 100 /var/images/qcowbak.img /var/images/storage.disk1.sys1

3) Boot DomainU that has below config.
	disk = [ 'tap:qcow:/var/images/qcowbak.img.img,hda,w' ]


I plan to start the investigation of the cause of this problem.

Has anyone already solved this problem?

Is 'qcowbak.img.img' a typo? By the looks of step 2, it should read
'qcowbak.img'

Yes, it is a typo.
a correct step 3 is as follows.

3) Boot DomainU that has below config.
  disk = [ 'tap:qcow:/var/images/qcowbak.img,hda,w' ]
