We need the spice support in Qemu. Does qemu-kvm 1.0 support for spice?

I tried the virtio-serial pieces with qemu.git and a RHEL6 guest. The guest was able to see the "com.redhat.spice.0" port. This suggests the problem was either fixed since QEMU 0.15 or that it only affects the Windows virtio drivers.

2). In Guest Windows XP OS
When the following callback function of the vioserial device is called in guest OS. The allocated resources is empty.
VIOSerialEvtDevicePrepareHardware() ---This function is to get the I/O address of the vioserial device and map the physical address to the logical address space.
I added the following trace and the value of nListSize is ZERO.
TraceEvents(TRACE_LEVEL_INFORMATION, DBG_PNP, "%s (nListSize=%d)\n",
__FUNCTION__,nListSize);
So far, we have tested Qemu 0.14 without any problem but Qemu 0.15 seemed to be broken in vioserial device.
Let me know if you need further information. Thanks.

I suggest trying qemu-kvm 1.0 or qemu-kvm.git because the issue may have been fixed since 0.15.
If the issue is still present, you could use git-bisect(1) to find the commit that caused behavior to change between 0.14 and 0.15.
Stefan
