Last modified: 2015-05-24 20:07:33 EDT
Description of problem:
qemu-kvm quit when get data from rng device in guest(RHEL6.5) after wakeup from S4.
Version-Release number of selected component (if applicable):
guest kernel: 2.6.32-419.el6.i686
Steps to Reproduce:
1.boot guest with rng-edg
# cat /dev/random | nc -l localhost 1024
-chardev socket,host=localhost,port=1024,id=chr0 \
-object rng-egd,chardev=chr0,id=rng0 \
2.do S4 on guest
#echo disk > /sys/power/state
3.wakeup guest and get data from rng device
hmp report 'qemu-kvm: virtio: trying to map MMIO memory' and qemu-kvm quit.
RHEL7 guest not hit this issue.
It's a bug of guest kernel, not qemu-kvm.
Should this bug be duplicated to 1008273? you mean they are the same issue, right?
