I think this is a known issue which has incorrectly been marked as
FIXED in bugzilla:

http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1117

there is a second bug report of the same problem, this time with more details:

http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1065

Is there a fix?

I vaguely recall there being a way to make xen "lie" to the OS about
the type of hypervisor, it might only be a feature on the commercial
citrix xenserver?

So basically there is no way to run Windows Vista or 2008 on Xen
without risk of a 101 BSOD under load?

If that is true then its a severe problem and Xen is useless for newer
MS OS's :(

Has anybody else had this problem and found a solution?

RE: Re: BSOD "A clock interrupt was not recevied onasecondary processor within the allocated time interval"

[Steve Prochniak]

Andrew - you can run the "Novell Shim" which makes the hypervisor
conform to the Microsoft spec enough that the guest OSs will turn off
watchdog timeouts (0x101 BSoDs)...

Alternative Viridian interface support was checked in. When enabled, it
ought to be sufficient to disable these bugchecks. Œviridian=1¹ needs to be
specified in the domain config file.

Keir,

Are you sure that the code was checked in? I am running 3.3.1 rc4 but
adding that setting didnt seem to help,  grep -r "viridian"
/usr/lib64/python2.5/site-packages/xen finds nothing, searching for
other config keywords in that folder they are always found in several

Ah, it's in xen-unstable only. Not in 3.3.

Hmm...  In order for the Viridian stuff to actually solve this
problem, you need to set the relaxed-timers bit.  It doesn't look like
the xen-unstable implementation does so.  Something like this might
help:

     }

But note that I haven't tested this *at all*.

[-- Attachment #1.1: Type: text/plain, Size: 7900 bytes --]


This is very similar to the patch we have on top of the original Novell stuff.

Steve Ofsthun was digging through the new viridian.c code at the end of the day yesterday to see if this bit was set. This fix below should do the same thing.

Hmm...  In order for the Viridian stuff to actually solve this

the xen-unstable implementation does so.  Something like this might

But note that I haven't tested this *at all*.

That appears to work. I have a test setup where I can introduce an 
arbitrary delay in qemu-dm. It's easy to trigger bug check 0x101 in 
Windows 2008 that way. Using viridian=1, with the relaxed timer bit set, 
I have been unable to crash Windows 2008.

Looks like a good thing to commit.

How do you introduce the delay? I'd like to try xen-unstable with
viridian=1 but I want to be absolutely sure that the issue is fixed so
if you have a patch for qemu-dm I'd appreciate it if you could post
it, the BSOD 101 issue causes serious problems for me because I am
using pci passthrough, I've found  if the domain using passthru
crashes, I issue "xm pci-detach", or "xm destroy" a domain that is
using a passthru pci device, will cause the entire machine to lockup ,
I've tried Xen 3.2.1/2/3 and 3.3.0/1 with various different kernels
but it always happens, so if my Vista or 2008 domains that are using
pci passthru usb2 cards BSOD at all it takes down the entire box,
usually resulting in data loss :(

Perhaps that problem might be fixed in unstable too, I will try it
tomorrow but it would really help to have a way to trigger a bsod 101.

Thanks

I use the attached change to qemu. In cpu_handle_ioreq, if send_vcpu != 
0,, it checks for the presence of a file called /tmp/qemu_delay. If it 
exists, it opens it and reads a delay value from it. Then it sleeps for 
that duration (in microseconds).

What I do is boot windows 2008, then open an editor to edit 
/tmp/qemu_delay. From the editor, I write various values to it. An easy 
way to trigger the issue is to write a large value (say, 8000000 for 8 
seconds), wait a little while, and then write 0 to make the domain come 
back to life. It should bluescreen at this point. Sometimes the 
procedure has to be repeated a few times.

If you want to do "echo $value > /tmp/qemu_delay", you'll need to change 
the hack to re-open the file each time, probably.
