yum isn't working inside vm

[wcwxyz]

I'm trying docker + runv-containerd + runv with stock kernel/initrd from hyperstart project.
After I run:
docker run -it --rm centos:6 /bin/bash

Inside the vm:

[root@4a2b5ba9b6ef /]# yum
rpmdb: mmap: Invalid argument
error: db3 error(22) from dbenv->open: Invalid argument
error: cannot open Packages index using db3 - Invalid argument (22)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

I tested with centos:7, yum/rpm is working fine.

@wcwxyz can you show the output of the following comand?

yum --debuglevel=3 clean all
yum --debuglevel=3 makecache

It seems like a 9p filesystem issue. After I modified hypertstart to mount 9p fs with "trans=virtio,cache=mmap", it works.

This rpmdb open failed error is fixed with hyperhq/hyperstart#74

The remaining yum Rpmdb checksum is invalid issue is tracked in hyperhq/hyperstart#88. So close this one.
