What is the state of blktap2?

What is the state of blktap2?

[David P. Quigley]

I'm currently working on moving storage services into their own domain
and I've been looking at blktap2. I've been trying to get an image
mounted with blktap2 and for some odd reason and tapdisk2 keeps hanging
instead of quitting at the end. I haven't removed any of the storage
startup code at this point so everything should be as it normally is in
xen-unstable. Is this a known bug? Are there some requirements on
blktap2 that I'm possibly not meeting? Is there anything in particular
that I should be looking at to try to debug the problem?

What kernel are you using? pv_ops dom0 kernel doesn't have working blktap2 yet..
linux-2.6.18-xen has working blktap2 support.

I'm using the patches maintained by Andrew Lyon that are applied to
2.6.31.10. These are supposedly based on the OpenSUSE patches and can be
found at http://code.google.com/p/gentoo-xen-kernel/downloads/list. I
need a more recent kernel version so the 2.6.18 dom0 kernel isn't an
option for me.

Well if its just broken in general any suggestions on where I should
look to try and fix it? blktap2 seems to be my best bet for implementing
my component so if I need to fix it to get it working I'm fine with
that.

Are you running pvops?
Cheer up, after 2.6.23 it's not you but just broken.

The hang you encounter is likely blktap trying to remove a sysfs node
from within its own callback. That could be circumvented, but it's
likely not the only issue.

Ok. I'm not sure if those OpenSUSE patches have blktap2 support included?
I know that at least Citrix XenServer, XCP and XCI 2.6.27 kernels do have blktap2.

More details about the pv_ops dom0 kernel (2.6.31.6 currently): It has initial version 
of blktap2 patches, but they'd need some debugging, because they're not yet working.

Based on that I think it has some level of blktap2 integration.
Unfortunately its not clear if it has it all and if so at what point the
code was taken from.

I haven't had much success with pv_ops as a dom0 kernel in the past but
it would be more beneficial to try fixing blktap2 in the context of that
kernel then the Novell patches that I'm currently using. I'll try to
build the pv_ops kernel as a dom0 and if I can run it as a dom0
successfully I'll see what I can try to do to get blktap2 working on it.

Looking under drivers through a make menuconfig on the pvops kernel I
don't see an entry for blktap2. I just see the entry for blktap. I know
that blktap2 was supposed to replace blktap but in the Novell patches
they are two separate config options and I don't seem to be seeing the
second on in the pvops kernel. Do I just enable blktap under drivers and
use tap:tapdisk:<type> in the domU config to use blktap2?

It is pretty broken at present, and I'll probably commit a change to 
disable it for now.  Fortunately it looks like Daniel Stodden is going 
to have a crack at fixing it up.

Well if he needs any help feel free to ask. I definitely can justify

So I tried getting the pvops kernel working and it works fine as a
standard Linux kernel but when I try to run it on top of Xen once I get
to Linux I don't have any keyboard input. I'm using the grub conf on the
pvops page so that part of the config should be correct. I'm going to
try to update to the latest version of xen-unstable and of the pvops
tree to see if that fixes anything.

Here is a little script that fixes most common problems.

grep -q xenfs /etc/fstab || echo "xenfs                   /proc/xen               xenfs   defaults        0 0" >> /etc/fstab

Is this for a domU or a dom0 pvops kernel? I didn't think that the
terminal for dom0 would be changed to hvc but I'm new to this so I could
be wrong.

Dom0. Thought the sections aobut /etc/inittab and seceretty can be used
on DomU too.

I've been trying for the better part of today to get this working and I
seem to keep hitting a wall. I finally managed to get the kernel booted
but only with a serial console. I found out that some modules were
missing so that might have caused the lack of console support but now
the kernel won't boot to a prompt at all. I keep running into a null
dereference in the uhci driver. I can try to rebase Jeremy's patches
onto a newer kernel.org version but I'd first like to check to make sure
this isn't already a known problem with a solution.

You can try my .config files for pv_ops dom0 kernel, available from here:
http://wiki.xensource.com/xenwiki/XenParavirtOps

in the "Troubleshooting" section.. just use "make oldconfig" with them.

That is not good. First time I hear of it. You could compile most of the
USB drivers in your kernel, and also the storage controller ones.

Thanks for the suggestion. I am already using your config though so its
not clear to me if its a config issue. Once I got that working and
booting I keep getting null pointer dereferences in some other code
thats not xen related. The only reason it might be affected by xen is
because its complaining about something with the PCI space. The error
text is below.

The kernel or the config? I'm using the config given on the pvops wiki
page and I haven't made any modifications. Although I'm not sure if
SELinux is enabled so I might have to change that.

Yea I found this to be a little weird considering on other kernels the
uhci driver has no problems at all. Someone here thinks it might be an
issue with the ACPI aperture with things not lining up. I'm running an
optiplex 960 for my xen development box.

So I'm running on an updated Fedora 11 box. I've grabbed Jeremy's pvops
kernel from kernel.org and I'm using the latest xen-unstable tree as of
yesterday at 5pm. Several of the uhci host controller sections in dmesg
are reporting the same error but I have copied some of the error text
with the kernel oops below.

Uh oh :) That looks bad.. I haven't seen that on my testboxes.. 
so dunno really what would help.

Is Xen complaining something when that happens? Check "xm dmesg".

Do you have "loglvl=all guest_loglvl=all" options for xen.gz in grub.conf?

I don't see anything that immediately jumps out at me but I'm new to
this so I may be missing something. My grub config entry is below and I
have attached the entire output from boot to the oops that I get on my
serial console.

The kernel output. Can you boot the pvops kernel without Xen and provide
the 'dmesg' and 'cat /proc/interrupts' output please?

There are some extra options, but those shouldn't be the problem.
Cleaned up grub.conf:

title Fedora (2.6.31.6-pvops-dom0-dontedit)
	kernel /xen-4.0.gz console=com1 com1=115200,8n1 loglvl=all guest_loglvl=all sync_console console_to_ring
	module /vmlinuz-2.6.31.6-pvops-dom0 ro root=/dev/mapper/VolGroup-lv_root console=hvc0 earlyprintk=xen
	module /initrd-2.6.31.6-pvops-dom0.img
	module /xenpolicy.24


Maybe try adding dom0_mem=1024M to the xen-4.0.gz line.. that might have some effect.

So what happend to 0000:00:1a.0 and 0000:00:1a.1? In the Xen boot
those devices were the ones that failed:

uhci_hcd 0000:00:1a.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
uhci_hcd 0000:00:1a.0: UHCI Host Controller
uhci_hcd 0000:00:1a.0: new USB bus registered, assigned bus number 3
uhci_hcd 0000:00:1a.0: irq 16, io base 0x0000ff20
uhci_hcd 0000:00:1a.0: host system error, PCI problems?
uhci_hcd 0000:00:1a.0: host controller halted, very bad!
uhci_hcd 0000:00:1a.0: HC died; cleaning up
uhci_hcd 0000:00:1a.0: USB bus 3 deregistered
uhci_hcd 0000:00:1a.0: PCI INT A disabled
uhci_hcd 0000:00:1a.0: init 0000:00:1a.0 fail, -108
uhci_hcd: probe of 0000:00:1a.0 failed with error -108

But they don't show up in your bootup here? So did somethinh change? Did
they get initialized later?

Can you provide the 'lspci -vvvv' from your bare-metal? Wonder what the
1a.0 and 1a.1 show as.

Ahh sorry about that. I removed the uhci module from the kernel build to
see if I could get the pvops kernel to finish booting. I've rebuilt it
with uhci back in and here is the updated dmesg and interrupts.
Something that was odd when I took the uhci driver out was that it hung
just after the failure to initialize the radeon driver which both dmesg
outputs have in them so I don't think thats the problem. Just after that
it hangs.

Re: Xen 4.0 + PVOPS + Intel VTD + USB EHCI = BUG()

[David P. Quigley]

I have a small update on the problem. It does seem like it is tied to
VT-D because I just turned it off in the bios and the dom0 manages to
boot on top of xen and I can log in. Are there any options for VT-D that
you would like me to try to help pin point the problem?

At least update to the latest xen-unstable tree, since -rc2 got just released, 
and it has some VT-d fixes/changes.

I updated my xen-unstable tree and tried to turn VT-D back on and it
breaks booting again so we still have a bug on our hands.

Can you pls post the serial output? It should have warning messages if it is caused by VT-d.

Re: Xen 4.0 + PVOPS + Intel VTD + USB EHCI = BUG()

[Sander Eikelenboom]

Hello David,

From LKML I remember some suggestions about disabeling "Legacy USB" when using VT-d to me able to boot linux.
Perhaps this also works for you with xen+linux ?

So I've managed to get my dom0 booting on top of xen however now I'm
running into a problem where my domU is kernel oopsing on startup. The
traces I've gotten seem to be in the memory allocation functions.
Normally this is a sign of memory corruption. Considering this VM was
working perfectly with the 2.6.31.10 dom0 based on the Novell patches
and xen 4.0 I don't think it is the VM that is the problem (however I
can try starting it under kvm to be certain. Any suggestions on what I
can do to try to hunt down the memory corruption?

Hi Dave,

I found the DMAR (VT-d) was also enabled in pvops dom0 in the log. It should not happen because Xen zaps ACPI DMAR signature to prevent dom0 using VT-d. Could you apply below small patch to confirm that xen really zaps ACPI DMAR?

Hello,
	Attached is the full serial console output with vt-d enabled from the xen 4.0-pre ascii art to the kernel oops in dom0.

Hmm.. interesting.

You could try this: Set on_crash="preserve" in /etc/xen/<guest> cfgfile,
and when the guest crashes, run in dom0:

/usr/lib/xen/bin/xenctx -s System.map-domUkernelversion <domUid>

If your system is 64bit then xenctx might be under /usr/lib64/
That should give you a stack trace of the crashed guest..

I'll run that when I get a chance. I managed to get the domU booting. I
removed all of my debug statements off of the xen-4.0.gz line in my grub
entry and it worked. I'm not sure if that code is the cause or if it
just didn't stress a race condition that happens when the system is
running slower because of debug code.

Hmm.. I remember some discussions that "sync_console console_to_ring" might cause problems.
Not sure about that though.

I've attached the output from the patched xen hypervisor. I see the
message being printed out so it appears to be clearing the signature.

RE: Xen 4.0 + PVOPS + Intel VTD + USB EHCI = BUG()

[Han, Weidong]

It's so weird pvops dom0 still detects DMAR and enables it after zap DMAR signature in Xen. Dom0 should not detect DMAR in ACPI after the signature is zapped. 

I suspect that your USB issue is caused by this. Pls have a try with turn off VT-d in pvops config (# CONFIG_DMAR is not set) to see if it solves your issue.

Regards,
Weidong

I've attached the output from the patched xen hypervisor. I see the message being printed out so it appears to be clearing the signature.

So I managed to sucessfully book my pvops dom0 kernel with VT-D on in my
bios when I turned off DMAR from the dom0 kernel config. Is there
anything else you would like me to do to help hunt this bug down?

Could you dump ACPI in native Linux and Xen dom0? Let's see what 
difference between "zap" and "no zap" DMAR signature.

You can search and download acpidump. After install it, you can use 
following command to dump acpi table:

acpidump >acpidump.txt

Dump acpi table on both native Linux and xen dom0, and post dump files.

this out and I'll post the results when I do.
