[kernel-xen] Xen 4.1 and latest CentOS 7.2.1511

[Steffan Cline]

Steve,

Here is how I had installed it.

1) Installed CentOS 7 from an image I had
2) Installed Cloudmin which did this: (from an excerpt of http://cloudmin.virtualmin.com/gpl/scripts/cloudmin-gpl-redhat-install.sh) 
--------------------------------------------------
# Enable Xen kernels repo, if on CentOS 6
yum info kernel-xen >/dev/null 2>&1
if [ "$?" != 0 ]; then
	echo Enabling Xen kernel repo for CentOS 6 ..
	yum install wget
	yum install http://au1.mirror.crc.id.au/repo/kernel-xen-release-6-5.noarch.rpm
	if [ "$?" != 0 ]; then
		echo .. repo install failed
		exit 1
	fi
	echo .. done
	echo ""
fi


# YUM install Perl, modules and other dependencies
echo Installing required Perl modules using YUM ..
yum install -y perl openssl perl-Net-SSLeay vixie-cron bind bind-utils kernel-xen kernel-xen-devel xen xen-libs lsof perl-Data-Dumper
if [ "$?" != 0 ]; then
	echo .. install failed
	exit 1
fi
yum install -y perl-JSON
yum install -y dhcp
yum install -y openssh-clients
echo .. done
echo ""

————————————————————————
3) Did a reboot, all was well using the Xen kernel vmlinuz-4.1.15-2.el7xen.x86_64.

4) Did a yum update, all seemed ok, rebooted and ended up in the new CentOS kernel.

5) Changed it back using grub2-set-default 2 (which was the xen kernel)

6) Reboot - stuck in dracut.

	


Thank you,
