windows 2016 kernel dump log
Only skylake host can reproduce this issue, issue cannot reproduce on Haswell host and Broadwell host
Issue also cannot reproduce with win2012 r2 guest and win10 guest on same skylake host Chaning the component to backport b65d6e17fe22 ("kvm: x86: mask out XSAVES"). No RHEL6 QEMU CPU models have XSAVES, so proper CPU feature description could get rid of most problems, but a kernel patch is needed as QEMU would still pass all XSAVE features with "-cpu host" and therefore fail on Skylake. Red Hat Enterprise Linux 6 is in the Production 3 Phase. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. The official life cycle policy can be reviewed here: http://redhat.com/rhel/lifecycle This issue does not meet the inclusion criteria for the Production 3 Phase and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification. Note that a strong business justification will be required for re-evaluation. Red Hat Customer Support can be contacted via the Red Hat Customer Portal at the following URL: https://access.redhat.com/ |
