Please help to take a look at this. @Ace-Tang

In addition, I thing we need to add more CI test case for runV part, although it will use nested virtualization which leads to some difficulties. @chuanchang

[Ace-Tang]

@fanux , it seems you must upgrade your qemu version >= 2.9

[allencloud]

it seems you must upgrade your qemu version >= 2.9

If this is an essential part, I think we need to update the runv related doc https://github.com/alibaba/pouch/blob/master/docs/features/pouch_with_runV.md .

Have you tried qemu version >= 2.9, we are looking forward to seeing the result. @fanux
In addition, we are planning to use azure which could use nested virtualization to integrate CI for runv part testing. @chuanchang
After that, we could have more specific experiment data then.

Build qemu from source, and solved this issue.

wget https://download.qemu.org/qemu-2.12.0.tar.xz
tar xvJf qemu-2.12.0.tar.xz
cd qemu-2.12.0
./configure
make

git clone git://git.qemu.org/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
make
