I've completed my client migration, and those guests are also surviving nicely. So I"m tagging this [SOLVED] and tossing in a few subject line keywords for the archives, to help other find this, and I've now brought back one of my (no longer in use) hosts to credit2 so I can start crashing that guest and hopefully capturing debugging information from it.
That is great to hear... looking forward for some more info and logs on the subject.
I'll report that data directly to xen-devel since that seems to not be an OpenSuse problem.
Yep, this is definitely an upstream issue, and we definitely should talk on upstream MLs. It would be useful, though, to have a bug opened for it for better tracking (see below).
Apart from OpenSuse possibly making "sched=credit" a Xen boot default now, via an update or whatever, there is one other small item of interest for this group. It has been suggested ( https://lists.xenproject.org/archives/html/xen-users/2020-02/msg00052.html ) that Xen 4.12.2 contains fixes to these and other problems. I do not know how these things work within OpenSuse, but I wonder if bringing in Xen 4.12.2 as an update to OpenSuse 15.1 might be a useful thing to do? I through that out there for all of you who know much more about these things than I.
In general, fixes are applied (backported). Whatever the fix for this would be to really revert to "sched=credit" or some actual changes to Credit2 (or whatever else), I think you can expect for it to be backported to any supported distribution.
Anyway, I expect this to be my last message on this topic to this group, but wanted to thank all of you who responded to me over the past months again for your help and patience.
Actually, thank you again for reporting the problem and for you will to
help us find the solution.
As I mentioned above, would you be willing to open a bug, on
https://bugzilla.opensuse.org/ about this? It is indeed something we'll
deal with upstream, but I think it would still be useful.
In the description of the problem, you can mention the fact that the
problem is being investigated and link the threads on the xen-devel and
xen-users mailing lists.
Thanks and Regards
