错误1:Nova节点无法启动
ERROR oslo_service.service InternalError: Nova requires QEMU version 2.1.0 or greater
解决:
错误报的很明显，qemu版本必须>=2.1.0，但centos7默认的qemu版本为1.5.3，所以必须升级qemu
1.安装
yum -y install gcc gcc-c++ automake libtool bzip2-devel
libuuid-devel spice-protocol spice-server-devel usbredir-devel
bison flex libaio-devel libcap-devel libiscsi-devel
可选yum -y install git
glib2-devel libfdt-devel pixman-devel
zlib-devel
tar xvJf qemu-2.10.1.tar.xz
cd qemu-2.10.1
./configure --enable-usb-redir --enable-libusb --enable-spice
--enable-kvm --enable-bzip2 --prefix=/opt/qemu --enable-linux-aio
--enable-system --target-list=x86_64-softmmu,x86_64-linux-user
make -j4 && make install
2.备份原始qemu
mv -f /usr/libexec/qemu-kvm{,.bak}
mv -f /usr/bin/qemu-img{,.bak}
mv -f /usr/bin/qemu-io{,.bak}
mv -f /usr/bin/qemu-nbd{,.bak}
3.建软链
ln -s /opt/qemu/bin/qemu-system-x86_64
/usr/libexec/qemu-kvm
ln -s /opt/qemu/bin/qemu-img /usr/bin/
ln -s /opt/qemu/bin/qemu-io /usr/bin/
ln -s /opt/qemu/bin/qemu-nbd /usr/bin/
4.重启nova-compute
systemctl restart openstack-nova-compute
