看样子百度还是不如google啊.百度上找到的信息完全无用.google上却给我找到了...
1：当/dev/xvdd does not exist错误出现时,可以尝试下
mount /dev/cdrom /mnt/xs-tools
2:xen-tools的安装过程:
cd /mnt ls mkdir xs-tools mount /dev/xvdd /mnt/xs-tools/ #/dev/xvdd does not exist #如果xvdd不存在则会提示:/dev/xvdd does not exist.这时候来尝试下/dev/cdrom mount /dev/cdrom /mnt/xs-tools/ #mount: block device /dev/xvdd is write-protected, mounting read-only cd /mnt/xs-tools/Linux/ bash install.sh
为linux安装xen-tools提示/dev/xvdd does not exist
