Xenserver/ESXi/Proxmox/Acropolis are out because of software R6 and having a single host, so I'm turning to openSUSE. I've worked a lot with Xen years ago but I understand the guys that get all the attention these days are KVM and docker, and Xen might be a second class citizen.

Given I would like: - Software R6 on the host

Not sure what that is...

- Virtualization nesting

KVM has some nested virtualization support, depending on your hardware. See this blog post for some help on it:

- PCI passthrough

Both Xen and KVM can do it.

- Some permanent VMs - Lots of temporary VMs

Would you suggest to go with XEN or KVM or Virtualbox in this specific scenario at this point in time?, can I assume docker will place nice with any of them?.

I would suggest KVM + virt-manager + libvirt. If you need a web UI, you can also try Kimchi. Docker has a different use case than a plain old VM: docker can't do system containers and you would only have one app in one container... and remember containers aren't secure, you need to put them in a VM to be on the safe side ;)

Hope that helps,

Thanks for your comments, by R6 I was refering to BTRFS on raid 6 + disk encryption. This box will works as a NAS also.

Regards,

Not sure about btrfs choice for storing image you will have to use the nocow plus I'm not certain that raid especially the level 6 is mature enough on btrfs ( regarding its difficulties to maintain itself up and running without assistance )

Software raid6 is still cpu expensive, for myself I'm using a good hardware controller and which handle raid6 + battery in case of crash.

The system is then build around lvm (each vm has its own).

my 0.05 Sfr cts ( +/- 0.02 cts € ) ;-)

Thanks, in this case the hardware can handle it. I'll add a UPS to the mix and it should be rock solid... Regards, -- Ciro Iriarte http://iriarte.it -- -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org
