1、KVM中宿主机通过console无法连接虚拟机 1)为KVM客户机添加virsh console支持 http://www.linuxidc.com/Linux/2013-02/79556.htm 2)利用vnc或宿主机的桌面进入客户机vm01中添加参数 #添加ttyS0的安全许可，允许root登录: echo "ttyS0" >> /etc/securetty #在/etc/grub.conf文件中为内核添加参数: console=ttyS0 这步要注意： console=ttyS0一定要放在kernel这行中(大约在第16行)，不能单独一行，即console=ttyS0是kernel的一个参数，不是单独的，如下(往右拉进度条，在最后): vim /boot/grub2/grub.cfg #grub.conf generated by anaconda #...... kernel /vmlinuz-2.6.32-431.el6.x86_64 ro root=/dev/mapper/VolGroup-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD rd_LVM_LV=VolGroup/lv_swap SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=VolGroup/lv
