Rafael Fonseca's questions

I've been reading up on OpenStack and how we can re-create an EC2/S3-style cloud for our internal development and I'm having a hard time finding information on how the OpenStack cloud controller provides redundancy of the cloud management services.

I know I can setup multiple Swift and Nova nodes, but not a single document/article/howto/wiki contains information on:

a) what happens if the cloud controller node dies; and b) how to setup redundant cloud controllers.

It seems to me that, although it is massively scalable, there is a big single-point-of-failure built into OpenStack.

Can anyone with more experience on OpenStack please shed some light as to how it all works in regards to high-availability?

I need to get files from a Linux VM that was hosted on an iSCSI volume attached to a XenServer host, but I no longer have any XS hosts around (they've all been converted to VMware).

I've already gotten to the point where I can mount the volume group (LVM) available on that iSCSI LUN, and I can see all the disks that were previously used by VMs in that LUN.

But neither mount nor fdisk can detect the FS type (presumably because they can't read VHDs). I've even tried using vdfuse, but no luck in getting it to work.

Does anyone have any ideas on how I can get this to work?
