Re: iPhone & Android App in progress !! Given that it works perfectly fine logging in using the QuadProx app on Android and using Proxmox's management console, I wonder if there's something I need to enable in terms of the API on the Proxmox side? I didn't see any documentation suggesting that...

I purchased this app from the U.S. App Store. Unfortunately it's hard to evaluate the app as it seems that logging in to a cluster using PAM auth doesn't work. I've used QuadProx's Android app, which works really well.

spirit, mmenaz ... others, I've been using the exact process described by many in this thread "cloning" KVM machines, essentially having a backed up VM as a "template." Works well and it usually takes less than 5 mins to get a new, clean VM provisioned. Granted, it includes some manual steps...

Run a backup of an existing server and restore it to a new VM. I have a bunch of KVM templates built specifically for this purpose. Then just create a new MAC address for your NIC, regenerate the SSH keys, re-IP the VM and change the hostname. 5 mins and you have a "cloned" VM.

For speed, consider putting in two small SSDs as cache and log disks. It should greatly improve the performance of your storage machine. I've run FreeNAS 8 on the N36L. The speed is OK, but it would be much better with caching and ZIL SSDs. Perhaps OpenIndiana or Solaris would do better than...

I found the answer elsewhere. AFAIK at this point there is no dpkg-reconfigure equivalent in openSUSE. The way to do it is to simply run: rm /etc/ssh/ssh_host_* ... and then restart the VM. sshd automatically regenerates keys if there are none in /etc/ssh/.

This may not be the right place for this question, but I figured I'll try anyway. I've built an OpenSUSE image that I want to use as a base image with the intention of "cloning" it over and over. Obviously, I want to regenerate the SSH config and recreate new keys for security reasons. I...

Maybe you could buy a cheap USB-to-Ethernet converter and just run backups of your VMs, or just copy over your databases and critical data. It would be slow, but if you can find a USB-to-Ethernet converter that works with Debian, I'm guessing it would work.

I'm with marotori, but I would probably put it on two 1U machines and build a two-unit cluster. That way you have some redundancy and protection in case of hardware problems on one server. Now, for the Atom boxes, they would make for good NAS boxes to house backups and could even run as shared...

With that setup I would probably just do a standard RAID1.

Well, in that case, install Debian Squeeze, configure your two drives in software RAID1 and then install Proxmox on top of it. There are examples/tutorials of how to do it here on the forums. Just search the forums and you will find it.

Buy a hardware RAID card. It's the best solution. Configure RAID1, install Proxmox and you're done.

@dups Check out the Openvpn for Android app. It works beautifully, even without root. Once logged in using OpenVPN, you can get to your Proxmox server(s). You could even run your OpenVPN server as a VM inside Proxmox, although that may be a bit of a gamble.

Hi, I'm sure you could, technically, make a script to mount and unmount the NASes, but it would need to be integrated with Proxmox so that it's aware of the action, because the shares are mounted by Proxmox and not through other means. In the end you may end up with too much of a "hacked...

Ceph RBD is good enough. :) Looks really promising. Maybe GlusterFS, which is supposed to be included in KVM 1.2, will be an option too down the road? I guess its speed is the big question mark.

@wipeout_dude I have no hard evidence for this, but according to what I've read, GlusterFS 3.3 has massive speed improvements and a lot of optimizations, specifically for running as a VM storage backend.

@spirit You got nearly three times the IOPS with Sheepdog compared to Ceph? What hardware configuration is that on? Interesting no matter what ... :)

Hi, I'm not sure you want to do it this way. Others may disagree with me. It sounds as if you're trying to mimic a tape system by rotating stuff offsite. I guess that's your whole point with the swapping the NASes in and out, to take backups offsite? What's your incoming and outgoing bandwidth...

@michaeljk Yes, that's my understanding. I don't think CephFS is implemented in Proxmox. Perhaps that is coming. @dietmar Sounds great. You guys are doing an amazing job. I'm looking forward to more news about Ceph, and maybe Sheepdog too, in Proxmox.

Yes, the latest kernel update in Proxmox 2.1 has support for Ceph as a storage backend, using RBD. It's basically a technology preview at this point, if I understand it right. Thus, it's not a "supported" feature. Some people on the forums have already implemented it. Search around on the forums...
