Hi,
I'm trying to use stub domains for IO for HVM domains, under Xen 4.1.2
with xl toolstack
The domain works fine with either qemu-xen-traditional or qemu
upstream, but I'd like to try stub domains.
If I understand the doc correctly just adding
"device_model_stubdomain_override = 1" to the config should do the
trick.
However doing that doesn't really work.
- qemu-dm is still started in the dom0 which AFAIU shouldn't be the case.
- There is a xxx-dm domain that starts so that's a good sign, however
they both stay stuck like :
wxp-00 7 1531 1 ------ 0.0
wxp-00-dm 8 32 1 ---sc- 0.0
Here's the xl -vvv log :
