There is still a solution!Ĭonnect to the physical host and shut down your virtual machine (here called vm.): # virsh destroy vm.ĭefine where the virtual machine image file is located (by default in the /var/lib/libvirt/images directory with a name like vm.): # virsh dumpxml | grep "source file="
Sometimes you have lost all links to your virtual machine (error in the /etc/fstab file, ssh configuration, etc) and, as you didn’t set up any virtual console, you are in real trouble. Red Hat Enterprise Linux Server 7.0 (Maipo) With KVM, connect to the virtual machine’s console (here vm.): # virsh console vm. Now, reboot the virtual machine: # reboot Note: Alternatively, you can edit the /etc/default/grub file, add ‘ console=ttyS0‘ to the GRUB_CMDLINE_LINUX variable and execute ‘ # grub2-mkconfig -o /boot/grub2/grub.cfg‘.
On the virtual machine, add ‘ console=ttyS0‘ at the end of the kernel lines in the /boot/grub2/grub.cfg file: # grubby -update-kernel=ALL -args="console=ttyS0"
If you aren’t under X Window, there is another way to access a virtual machine’s console: you can go through a serial console. With KVM, to access the virtual machine’s console under X Window, type: # virt-manager
