[Libguestfs] virt-edit Guestname /boot/grub/grub.conf error

Hello, I get the following message on virt-edit Guestname /boot/grub/grub.conf. I have executed the command. guestmount –ro -a /var/lib/nova/instances/instance-00000001/disk -m /dev/sda1 /mnt guestmount -d instance-00000001 -i –ro /mnt root@compute:~# virt-edit instance-00000001 /boot/grub/grub.conf libguestfs: error: error: domain is a live virtual machine. Writing to the disks of a running virtual machine can cause disk corruption. Either use read-only access, or if the guest is running the guestfsd daemon specify live access. In most libguestfs tools these options are –ro or –live respectively. Consult the documentation for further information. root@compute:~# Please help how to get past this. Regards, Sandeep.
