[Xen-devel] win-pv assertion failed while migrating

hi all

i migrated a guest os with win-pv driver (changset 820) , xc_save process
hung like that

Not sure if it''ll make a difference, but you should at least
upgrade to Xen 4.0.1 and dom0 kernel from xen/stable-2.6.32.x branch.

2.6.31 dom0 kernel is not supported or maintained anymore,
and it''s known to have bugs/issues.

[Xen-devel] Re: win-pv assertion failed while migrating

i upgrade to the latest version(changeset 849),  assertion failure still
exists. due to some reason, my env must be xen4.0.0, 2.6.31.13.
if there''s some patches about xen,dom0 to deal with this problem, i can
backport to current version

I don''t have machines that are similar enough to be able to actually
test migration, so the best I can do is test suspend/restore. Can you
try doing that and see if you can reproduce the problem under those
circumstances?

Also, what OS are you using? Is it Windows 2003?

[Xen-devel] Re: win-pv assertion failed while migrating

yes, windows 2003-32.

my test is migrate vm between host A and host
B continually(xen4.0.0.0+2.6.31.13)

Almost after automatic migrate script ran for one day, this problem appeared

maybe i can also do some test on xen4.0.1+2.6.32.x to check whether it
matters kernel or pv driver.

So you are saying that it doesn''t happen immediately, only after some
time? Do you know how many times?

Maybe I''m leaking a resource somewhere every time migrate happens and
eventually it runs out...

Does the problem get worse if there is high network activity at the time
of migration?

How many network adapters do you have on your DomU? I can see it calling
resume twice.

Thanks

[Xen-devel] RE: win-pv assertion failed while migrating

I''ve found a race in xennet that could cause the problems you are
seeing
and have pushed a fix, but it''s not well tested. From what
you''ve said I
think you can build from source. If not, I should be able to upload some
binaries tomorrow. Please let me know how your testing goes.

[Xen-devel] Re: win-pv assertion failed while migrating

I build from source. today, i''ll use latest version to test, if
there''s any
results, i''ll let u know

[Xen-devel] RE: win-pv assertion failed while migrating

I have just pushed a fix. It was a stupid mistake on my part and I
didn''t notice it because Windows 2008 doesn''t seem to crash on
ASSERT
failures.

Please try it now.

Thanks

[Xen-devel] Re: win-pv assertion failed while migrating

i forgot to record the BSoD code

migration times wasn''t regular,  and phenomenon weren''t the
same.

the new test showed vm rebooted once, and also failed to migrate

[Xen-devel] RE: win-pv assertion failed while migrating

Hmmm... I''m not getting any logging on mine.

Do you have a crash dump? I''d need the pdb file for xenpci if you do.

The address being free''d according to the bug check is
0xFFFFFA8000000000, which appears to be allocated here:

XenPCI <-- XenPci_DeviceWatchHandler 
XenPCI     XEN_INIT_TYPE_RING - tx-ring-ref = FFFFFA8000000000 
XenPCI     XEN_INIT_TYPE_RING - tx-ring-ref = 16228

I''ve posted on ntdev mailing list to see if anyone else thinks it
strange that the address is such a round number.

James
