Subject: 4.14.x host - KVM guests crashing
Date: Fri, 9 Feb 2018 14:16:00 +0100 [thread overview]
Message-ID: <20180209131600.GC14309@pcnci.linuxbox.cz> (raw)
Hi,
I just wanted to report, since we started rolling to 4.14.x kernels,
we've experienced multiple KVM guest panics (with 4.14 on hosts)
We've first hit it with 4.14.12, yesterday I had similar problem with 4.14.16.
backtraces can be observed here:

http://nik.lbox.cz/download/guest-panic-host-4.14.16.png
sorry I don't have anything more complete
they are a bit different, but there are some similarities (ie double_fault)
also important to note, both are from different host systems.
after reverting hosts to 4.4, crashes are gone.
it takes quite long time (more then day) for crash to occur
my question is, did anyone hit similar problem? Is this something
known, maybe fixed in 4.14.17 or latest GIT?
Can I provide some further debug info?
BR
nik
