Xen devel - Apr 2007 - PV driver on hvm guest save&restore status report w/ cset 14797

From the testing, we verified that the issue of VNIF restore failure on pae host
has been fixed. Right now, for ia32 up guest on pae host, pv drivers
save&restore work well, but for ia32 smp guest on pae host, still some
issues remained. We skip the testing for ia32e host for pv drivers build fail.
The detail report is:

pae platform:
~~~~~~~~~~~~~~~~
  Ia32 UP:
-----------
      Copy files in guest and save&restore one time, VBD pass
      Copy files in guest and save&restore many times, VBD pass
      Scp files to another machine from guest and save&restore one time,
VNIF pass
      Scp files to another machine from guest and save&restore many times,
VNIF pass
  Ia32 SMP: 
-----------
      Copy files in guest and save&restore one time, VBD pass
      Copy files in guest and save&restore many times, VBD fail
      Scp files to another machine from guest and save&restore one time,
VNIF pass
      Scp files to another machine from guest and save&restore twice, VNIF
fail

ia32e platform:
~~~~~~~~~~~~~~~~
　PV drivers build fail for both UP and SMP guest
　
　
Attached is xend.log for the smp guest pv driver save&restore many times
fail condition.



Best regards,
Fan

Which PV drivers do you have installed?

In particular, if you have xen-platform-pci.ko installed, you _must_ also
have xenbus.ko and reboot.ko since the tools assume that if the callback
has been activated, the guest will suspend itself.

Looks to me from logs like you may have xen-platform-pci.ko, but not
the other two...


cheers,

S.

Hi Steven,
Thanks for your reminding, definitely I have inserted xen-platform-pci.ko,
xenbus.ko, xen-balloon.ko and reboot.ko. If I only insert xen-platform-pci.ko,
pv drivers(vbd, vnif, balloon) could not work, so I am sure that pv drivers
themselves work before save/restore.

Best regards,
Fan

I think xenbus.ko is removed? There are only xen-platform-pci.ko,
xen-balloon.ko, xen-vnif.ko and xen-vbd.o after build PV drivers in 32 bit
system.

Yes, I noticed that xenbus.ko was removed w/ cset 14797, so I inserted all the
other pv drivers except the removed one, and with cset before 14797, such as
14773, I am sure I have inserted all the required modules to make pv drivers
work, including xenbus.ko.

Best regards,
Fan

Looks like the guest becomes unresponsive. I''ll see if I have time to
take a
look.
