Bug 1052090

The virtio-serial driver fails on this test as well.

It also seem that the problem only exists when running with a RHEL-7 host. I was unable to reproduce this error with a RHEL-6 host, no matter which qemu-kvm version was used (both stock rpm and upstream).

Which host is running the guest? Is it an AMD or an Intel? (cat /proc/cpuinfo). Thanks.

it's an Intel host

Does the job still fails if you remove the "-cpu Penryn" option?

The test pass if I switch to "-cpu kvm64" so it looks like a kvm issue (missing a sse instruction?).

From the trace:

Karen, can you please assign this bug to the proper person? Thanks.

lijin ,pls re-test with following tests 
1.-cpu kvm64
2.remove -cpu 
3.-cpu penryn,+sse

remove "-cpu Penryn",still hit this issue;
“-cpu kvm64”,job can pass
"-cpu penryn,+sse",job can pass

Boot rhel7.0 guest with "# /usr/libexec/qemu-kvm -m 2G -smp 2,cores=2 -cpu Penryn"

can find sse flag inside guest. so seem this problem don't relate with sse flag(needn't +sse).

cat /proc/cpuinfo inside guest.

pls test it w/ windows 8.1-32 guest

Rerun this job on our slot machine,job can pass with the same command line with comment#0

Boot windows 8.1-32 with "-cpu Penryn", "sse" flag can be found inside guest. so cpu flag sse does not have an associated with this problem.
