5. no error ,no crash.
Meng, It seems the bug had been reported on qemu-kvm of RHEL7, we should reproduce it on the corresponding versions. Thanks! Nini will try on rhel7.4 host using qemu-kvm , will update when i am done tryied on both qemu-kvm-rhev & qemu-kvm qemu-kvm-rhev: qemu-kvm-rhev-2.8.0-1.el7.x86_64 qemu-kvm: qemu-kvm-1.5.3-126.el7_3.3.x86_64 and the steps is exactly like #comment 14. and the results is ok, no error, no coredump , no crash. (In reply to Yang Meng from comment #17) > tryied on both qemu-kvm-rhev & qemu-kvm > > qemu-kvm-rhev: qemu-kvm-rhev-2.8.0-1.el7.x86_64 > qemu-kvm: qemu-kvm-1.5.3-126.el7_3.3.x86_64 > > and the steps is exactly like #comment 14. > > and the results is ok, no error, no coredump , no crash. Given these results and the fact this BZ is very old, I'm closing it. Please reopen if it ever reproduces. Thanks. |
