安装NBD驱动
一.配置本地yum源
1、挂载系统安装光盘
# mount /dev/cdrom /mnt/cdrom/
# mkdir /mnt/media
# cp -rf /mnt/cdrom/* /mnt/media
2、配置本地yum源
# cd /etc/yum.repos.d/
#vi rhel-source.repo
[rhel-source]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
#baseurl=ftp://ftp.redhat.com/pub/redhat/linux/enterprise/$releasever/en/os/SRPMS/
baseurl=file:///mnt/media/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[rhel-source-beta]
name=Red Hat Enterprise Linux $releasever Beta - $basearch - Source
#baseurl=ftp://ftp.redhat.com/pub/redhat/linux/beta/$releasever/en/os/SRPMS/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

二.编译安装NBD驱动
1. yum install kernel-devel kernel-headers (本地yum源安装!!)
2. cd /tmp
3. wget http://vault.centos.org/7.0.1406/os/Source/SPackages/kernel-3.10.0-123.el7.src.rpm (这里内核一定跟需要安装NBD驱动的内核一致!!)
4. rpm -ihv kernel-3.10.0-123.el7.src.rpm
5. cd ~/rpmbuild/SOURCES
6. tar Jxvf linux-3.10.0-123.el7.tar.xz -C /usr/src/kernels/
7. cd /usr/src/kernels/
8. mv $(uname -r) $(uname -r)-old
9. mv linux-3.10.0-123.el7 $(uname -r)
10. cd $(uname -r)
11. make mrproper
12. cp ../$(uname -r)-old/Module.symvers ./
13. cp /boot/config-$(uname -r) ./.config
14. make oldconfig
15. make prepare
16. make scripts
17. make CONFIG_BLK_DEV_NBD=m M=drivers/block CONFIG_MODULE_SIG=0 CONFIG_MODULE_SIG_FORCE=0
18. cp drivers/block/nbd.ko /lib/modules/$(uname -r)/kernel/drivers/block/
19. depmod –a
20.modprobe nbd max_part=16
21.qemu-nbd -c /dev/nbd0 sdapath/sdname1.qcow2
22.qemu-nbd -c /dev/nbd1 sdapath /sdname2.qcow2
23.lsmod grep|fuse
24.lsmod grep | nbd
