Libguestfs - Feb 2013 - 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 at 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 at compute:~#

Please help how to get past this.

Regards,
Sandeep.

As the error says, this can't be done.  You can't use virt-edit on
live virtual machines.
