Re: [Libguestfs] grub-install with guestfish

Hello Mr Richard Jones, First of all, thank you for the amazing tools that you are creating. I'm new to the virtualization and libguestfs ,so I'm hoping you can help me to at least understand what's the problem I'm having exactly or to know if there's a way to resolve it , and any suggestion or advice is much appreciated. I have a problem while trying to create a vm (the method I'm using is to copy the filesystem of a template in a newly created lvm device and I modify the fstab file and grub.conf with the uuid of the newely created device) but the vm get stuck in booting from hard disk , while using xen I switched the vm to a pv guest and used pygrub and now the vm is working properly , the problem is with kvm (installed on ubuntu 14.04) the vm (centos guest) is always stuck in the booting and didn't find a tool like pygrub on kvm , the only way to make the vm work is to manually install grub through a livecd, I thought of using guestfish and use grub-install / /dev/sda but when I try to start the vm it is stuck in grub2.0.2 shell. It seems that with grub-install with guestfish it installed grub2 but in the man page of guestfish it's said that it only install grub1. So is it because kvm is installed on ubuntu that's why grub-install installs grub2?? and if the host is centos , wil I have problems with ubuntu guests while tring to install grub ??? So why even if I modified the /boot/grub/grub.conf inside the guest it still don't want to boot?? if the host is kvm on ubuntu will I have problems with centos guest and if the host is centos will I have problems with ubuntu guest?? I'm really confused wth all this , I don't know if I'm missing something. I'm not sure if I was clear enough , and if needed I can provide you more infos , but it's been a while that I'm stuck so any suggestion will be more than welcome , so thank you for your time and I hope I'm not bothering you.
