Oh, you are right. Wrong filename - it's my fault.

Rich, this wasn't operational. First of all, the image on my version of RHEV-H is kept in other directory. So I did that: 1. $ export FEBOOTSTRAP_KERNEL=/dev/.initramfs/live/vmlinuz0 2. $ echo $FEBOOTSTRAP_KERNEL /dev/.initramfs/live/vmlinuz0 3. $ libguestfs-test-tool ************************************************************ *

Unfortunately, placing the link into the /boot does not work. libguestfs-test-tool failes with the same message: ************************************************************ * IMPORTANT NOTICE * * When reporting bugs, include the COMPLETE, UNEDITED * output below in your bug report. *

Thanks, Itamar. Hooks are really great tool. No doubt we will use them. But I still need some clarification about interaction between hooks (on the manager's side) and libguestfs (on the side of hypervisor/storage).

Thanks a lot. Yes, we have a Support and we will ask them to help with this bug. How do you think, maybe we can hack this issue quickly just putting the kernel file (desired by libguestfs) manually to some directory on the RHEV-H file system? /boot and /lib/modules do not contain kernels on RHEV-H.

Rich, you are right; the hypervisor is RHEV-H. As Itamar has just explained me, hooks are executed on the hypervisor’s side (not on the RHEV-M, as I used to think), so properly working libguestfs on the RHEV-H will resolve my issue. Here is the output of the test tool: ************************************************************ * IMPORTANT NOTICE * * When

Hello, It's me again with one more misunderstanding of libguestfs usage... Guestfish (as well as python libguestfs module) refuse to mount logical volume containing the root partition of the VM's filesystem. According to this short guide<http://rwmj.wordpress.com/2009/04/07/libguestfs-lvm-support/> I am trying to mount /dev/vg_kojit/lv_root as "/", but nothing works:
