Additional info(cont): 3. Start or shutdown guest will both cause call trace in host. Re-assining to Luis Claudio, he's already backported the fix and is preparing a build. ==Verification== Versions: 3.10.0-679.rt56.602.el7.x86_64.debug(in both host&guest) qemu-kvm-rhev-2.9.0-7.el7.x86_64 libvirt-3.2.0-6.el7.x86_64 tuned-2.8.0-4.el7.noarch Steps: 1. Reboot rt host 2. First boot rt guest hit issue[1] 3. Repeat boot/shutdown/reboot rt guest several times, no error info shows in both host and guest. Hi Luis, there is still a problem with kernel-rt-debug in step2, as the issue looks different, so I filed a new bug[1]. Please feel free to set it as a duplicate bug and fail on_qa this bug. [1] Bug 1459739 - Call Trace shows in rt host with kernel-rt-debug when first booting rt guest Best Regards, Pei ==Re-verification== Versions: 3.10.0-680.rt56.604.el7.x86_64.debug(in both host and guest) tuned-2.8.0-5.el7.noarch qemu-kvm-rhev-2.9.0-9.el7.x86_64 libvirt-3.2.0-9.el7.x86_64 Steps: 1. Boot rt host 2. Boot rt guest 3. Repeat reboot/shutdown/boot rt guest several times, no error info shows in both host and guest. So this bug has been fixed well. Thanks.
