308 kernel guest reboot failed when there is high stress on host after running for a whole night
Unfortunately, RHEL5 is not as good as RHEL6 with high load, and KVM suffers from this too. We closed several such bugs, and closing this one too. Thanks, Ronen. Just a FYI, test suggest this situation exists in latest 5.8.z, so this is not regression. Test with: 2.6.18-308.14.1.el5 kvm-83-249.el5_8.5 |
