Centos 7 KVM + RBD Host
Hi;
Does anyone using CentOS 7 KVM + RBD Ceph Storage Hypervizor Host on
production! environment? The supplied version of libvirt is not compatible
for vm live migration(it doesnt like tcp connection without ssl) and need
to be recompiled for rbd support.
Now it looks like Ubuntu 14.04.02 is the only candidate for KVM + RBD host.
Thanks
Özhan

Hello Özhan,
take a look at the blog from widodh, he wrote a post how to rebuilding the libvirt under centos 7.1.

There is currently feature request to support auth_tcp=sasl on CloudStack
side ;) I hope that they will officially support soon :)

Hi;
libvirt will be successfully compiled with Widodh technique. But the
problem is the supplied version of libvirt with CentOS7 has problems on
starting with auth_tcp parameters with none authentication method, when you
start to use auth_tcp with none authentication, libvirt deamon refuse to
start. So either we need to use an older version of libvirt or we need to
wait CloudStack to support sasl authentication for tcp connections.
If someone knows how to start libvirt on CentOS7 with auth_tcp=none and
LIBVIRTD_ARGS="--listen" parameters that will also be helpful :)
Thanks
Özhan

Centos for now doesn have support for RBD/Ceph (qemu-* and libvirt) - there
was some nice explanations how to grab/compile RBD patches with qemu-* and
compile RBD with appropriate support.
Ubuntu 14.04. works out of the box... (if you can hanle other Ubuntu child
problems that are in some cases countless...like not being able to install
grub at the end of the OS installation on software raid etc...)
