3.1.x and 3.2.x releases

3.1.x and 3.2.x releases

[Keir Fraser]

Folks,

A new release candidate for 3.2.0 has just been checked into the
xen-unstable tree. It's available from staging and will be in the main tree
when it has passed internal regression tests.

Meanwhile, in preparation for 3.1.3, please let me know if there are any
further patches from xen-unstable that should be backported into the 3.1
branch. You can pull the xen-3.1-testing.hg repository to see what has
already been backported.

 Thanks,
 Keir

Any chance the sequence of timer/tick fixes that you, Dave Winchell,
Ben Guthro, Haitao Shan, and Eddie Dong were discussing/developing
over the last two months could get into 3.1.3?  Clocks that gain time
can cause some pretty nasty difficult-to-diagnose real customer
problems.

Thanks,
Dan

My 3.1 testing has revealed a problem when rapidly rebooting a single
domU. Eventually, xend gets a wrong type response in xs.c (it's
expecting a reply to XS_READ, and it gets a reply to
XS_TRANSACTION_END). This breaks everything horribly, as xend is very
poor at recovering from an error like this.

I'm still looking at it, but I wonder if people are doing a similar test
and if anyone else has ever seen it. The classic symptom is something
like:

# xm list
Error: (2, 'No such file or directory')
Usage: xm list [options] [Domain, ...]

Or more often EBADF

We caught a new issue for Xen 3.2 RC2. 

HVM domain restore failed and also local live mirgration failed.

I've done some very basic testing (again, no HVM) on Solaris bits based
on rc2, and it doesn't seem to have got worse.

RE: 3.1.x and 3.2.x releases

[Dan Magenheimer]

Thanks Keir... but in trying to test this, I find that timer_mode seems to be displayed in sxp debug output in xend.log for xen-unstable, but I don't see sxp output for timer_mode in xend.log for xen-3.1-testing (cset 15564).  Does timer_mode get properly set and passed down to xen in xen-3.1-testing simply by adding a (e.g.) "timer_mode=3" line in the config file?  If so, is there another way I can verify that?

Thanks,
Dan

Re: 3.1.x and 3.2.x releases

[Keir Fraser]

I only did a straightforward port of the xend parts, without much testing.
You could add tracing to the hvm_param hypercall in xen/arch/x86/hvm/hvm.c,
and see whether the timer mode is being set for your HVM guest that way.

I'm getting following build error with libvirt-0.4.0 on latest 
xen-3.1-testing.hg (i'm using gcc-3.4.6). 

I found [1] in xen-changelog mailing list while searching but it's already 
backported to xen-3.1-testing, is another patch needed or i'm missing 
something?

Re: 3.1.x and 3.2.x releases

[Keir Fraser]

It's not obvious what the problem is. DEFINE_XEN_GUEST_HANDLE() is defined
at that point in xen.h because we have used it earlier. This is also true
for uint8_t, uint16_t, etc. You'll have to do a bit more digging (e.g., use
gcc -E option to get the post-processed source, and see if that shows
anything obviously wrong).

Seems like

[...]
DEFINE_XEN_GUEST_HANDLE(uint8_t);
DEFINE_XEN_GUEST_HANDLE(uint16_t);
DEFINE_XEN_GUEST_HANDLE(uint32_t);
DEFINE_XEN_GUEST_HANDLE(uint64_t);

typedef unsigned int * __guest_handle_unsigned int;
typedef unsigned long long int * __guest_handle_unsigned long long int;

            __guest_handle_unsigned char edid;

Re: 3.1.x and 3.2.x releases

[Keir Fraser]

Oh, it's because your stdint.h type definitions are macros rather than
typedefs. I believe the C spec requires them to be typedef names (Section
7.18 of the C99 draft spec). It looks like the problem stems from the
stdint.h supplied with gnulib, included in libvirt-0.4.0. Why does libvirt
require its own stdint.h?

I'm pretty sure you'd have the same problem building against the 3.2.0-rc
public headers.

Well, we could call the handles uint8, uint16, and so on. That shouldn't
clash in the macro namespace. I'll see how invasive that is.

The gnulib stuff is for portability. The stdint.h in the gnulib/ directory
of libvirt will only be used on OS where there is no stdint.h present in
the regular /usr/include.

Can someone tell me what OS / platform the libvirt compile errors were
occurring on. stdint.h  is a pretty common thing so I'd only expect it
to be have been used when building libvirt on Windows, certainly not when
on Linux.

Dan.

Well, I hopefully fixed it now anyway, both in 3.1-testing and unstable.

RE: 3.1.x and 3.2.x releases

[Dan Magenheimer]

Hmmm....

I tried something a bit more dramatic.  In arch/x86/hvm/hvm.c, in the
case HVM_PARAM_TIMER_MODE, I changed the "goto param_fail;" to
"panic("BAD HVMPTM");" and added "timer_mode=6" in the config file, but
the panic was not triggered.  But the same code/config change in
xen-unstable DOES panic.

Am I missing something in configuring this for xen-3.1-testing?  Or
perhaps the 3.1 patch just isn't passing timer_mode down properly?

Thanks,
Dan

But i'm try to compile libvirt on Linux which has stdint.h in 
regular /usr/include :)

I did hit this when compiling 0.4.0 on Solaris.  I hacked around this with
the following patch, but figured I'd spend more time figuring out a better
solution before sending something upstream.  Still, it may be useful to
some.

Line 1542 of XendDomainInfo.py should be passing the mode down to Xen.
Presumably that is not working.

Also, I have a suspicion that timer_mode won't survive a save/restore of an
HVM guest, either in unstable or in 3.1-testing. I haven't confirmed this
though. But there's no code to do it, so unless it happens automagically...

On second look, it works fine.  (My fault... multiple python directories again :-(

Also, looks to me like timer_mode across save/restore is working fine too.

It's in the staging tree
(http://xenbits.xensource.com/staging/xen-3.1-testing.hg). I haven't seen
internal tests run for a while so they might be stalled for some reason.
I'll take a look in the next day or so.
