Hi,
not sure whether this is the best list to ask for that, but maybe somebody from -stable interested people has hit similar problem..
if it's not appropriate list to ask/report, please let me know
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:

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.
my question is, did anyone hit similar problem? Is this something know, maybe fixed in 4.14.17? (I'll give 4.14.17 try anyways I suppose) (or latest git?)
could it be related to page table isolation enabled hosts?
btw hosts are running x86_64 centos 7, guests are either centos 6 or centos 7
If I could provide any further info, let me know
BR
