free Sun 1RU servers
by Russell Coker 08 Jan '16

08 Jan '16

http://www.cpubenchmark.net/cpu.php?cpu=AMD+Opteron+254&id=1806 We have two 1RU Sun servers which each have 2 of the above CPUs. One server has 16G of RAM and the other has 32G. One of them has 2*70G 15000rpm SAS disks and the other has 2*140G. There is also a spare 70G SAS disk. One of the servers is currently in use as the LUV server but that is to be decommissioned. The other is at my home (we used it for the ZFS and BTRFS training). The servers are extremely noisy which is one of the reasons why I haven't done any other training on the server in my home (the other reason being that I have some other servers for this purpose). NB if someone wants to use these commercially then they can buy them from LUV. But they are free for home or non-commercial use. If I don't get any interest then I'll put the RAM and disks in the hardware library and the rest in e-waste. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Hi Trent, thanks. I thought of Chromebooks too. It may be an option. That you need a Google account to boot USB is very understandable;-) BTW: I just found this (when looking for open hardware and remembering the OLPC X0 I bought and sponsored ages ago): https://www.indiegogo.com/projects/infinity-a-computer-anyone-can-build-and… , http://www.one-education.org/ Regards Peter

Thus, whether you actually need virsh depends on your > requirements and environment. What you are saying is true, But inmho, virsh give you far more control over the VM (eg: snapshots, connecting devices live etc). While you may be able to do the same without virsh, using it to me is much easier, specially if you are doing it remotely.

I have accidentally removed some packages from a debian system and now I have lost networking and MATE. Can I reinstall the removed packages from the install cd?
