Comment 8 Miroslav Rezanina 2014-07-09 08:17:15 EDT

Fix included in qemu-kvm-1.5.3-66.el7

Comment 9 FuXiangChun 2014-08-04 23:17:43 EDT

Reproduced this bug with qemu-kvm-rhev-1.5.3-60.el7ev.x86_64 and "-M pc-q35-rhel7.0.0" or "-M pc-i440fx-rhel7.0.0"

result:
same as comment 0 

verify bug with qemu-kvm-1.5.3-66.el7.x86_64.

result:
1.Number of SMP cpus requested (161), exceeds max cpus supported by machine `pc-q35-rhel7.0.0' (160)

2.Number of SMP cpus requested (161), exceeds max cpus supported by machine `pc-i440fx-rhel7.0.0' (160)

As qemu-kvm-rhev version didn't fix this bug. so QE filed a new bug 1126666.
