[libvirt-users] Installing libvirt and Xen on Red Hat 7.5
Hi,
I am installing OpenStack on Red Hat 7.5. For Nova compute component, I
choose libvirt and Xen.
However, I am running into some problems. It seems libvirt is unable to
communicate with Xen.
Xen installation:
I installed Xen410 using "Xen make easy"
https://xen.crc.id.au/support/guides/install/. Here is a list of packages
installed and verification that Xen is running.
# lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 7.5 (Maipo)
Release: 7.5
Codename: Maipo

However, after installation, Nova complains "no connection driver available
for xen:///".
Also, virsh cannot connect Xen.

Then I check the connection drivers of libvirt. It seems the daemon driver
for xen is missing.

But I couldn't find the xen driver (libvirt-daemon-driver-xen) from yum. I
do find it driver on some websites (
http://rpmfind.net/linux/rpm2html/search.php?query=libvirt-daemon-driver-xen),
but I am not sure which is the right version to choose.
I also found this email
https://www.spinics.net/lists/centos-virt/msg05163.html.
Then I decided to compile libvirt from source code. So I checked out the
source code from github and tried to configure and compile it.
However, from the output of ./autogen.sh --system, I don't find driver for
xen is enabled. Actually, xen is not listed as driver in the output.

and make Nova work with Xen?
Thanks a lot in advance!
