Hi all. 
I have centos/7 on a VM Virtualbox... I want to install all the openstack python clients (nova, swift etc). 
I installed 
yum install centos-release-openstack-queens 

and all good but when I try to install one client I have the following error:

yum install python-swiftclient

<SNIP>

Trying other mirror.
To address this issue please refer to the below wiki article

https://wiki.centos.org/yum-errors
<SNIP>

Now the only way to install the package (or any other) is to disable that repo
yum-config-manager --disable centos-qemu-ev

then I can install the client...

Any idea? 
It looks like http://mirror.centos.org/altarch/7/virt/x86_64 doesn't exist.....
