Description Amos Kong 2010-05-06 07:57:00 UTC
Description of problem:
Start guest and the guest can get IP and can PING host. But the guest could not
get network and ping host after S4.

But it's fine when using e1000 or rtl8139 NIC.

Version-Release number of selected component (if applicable):
host kernel: 2.6.32-19.el6.x86_64
guest kernel: 2.6.18-194.el5
# rpm -qa |grep kvm

How reproducible:

Steps to Reproduce:
1. start guest
/root/autotest/client/tests/kvm/qemu -name 'vm1' -monitor tcp:0:6001,server,nowait -drive file=/root/autotest/client/tests/kvm/images/RHEL-Server-5.5-64-virtio.qcow2,if=ide,cache=none,boot=on -net nic,vlan=0,model=virtio,macaddr=00:30:1F:42:1e:6c -net tap,vlan=0,ifname=virtio_0_6001,script=/root/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 8196 -smp 1 -soundhw ac97 -usbdevice tablet -rtc-td-hack -no-hpet -cpu qemu64,+sse2 -no-kvm-pit-reinjection -redir tcp:5000::22 -vnc :0 -serial unix:/tmp/serial-20100506-153156-I71N,server,nowait

2. run S4
echo disk > /sys/power/state
3. start guest by the same cmd and ping host

Actual results:
the guest cannot gets network after S4

Expected results:
the guest can gets network after S4

Close as duplicate although this bug is about rhel5. The real issue is that virtio in a guest doesn't support PM.
