Hi out there! Before I start installing and fiddling around: Are there any reasons AGAINST setting up a Lustre playground in a VirtualBox environment? I just want to play around w/ recovery and debugging situations and upgrades. No performance required at all. Anybody already set up a virtual environment for such a purpose? Any "best practice" or something? Thanks for answers! wolfgang

Good that you recognize that the performance will be quite bad though. Make sure that you provision the hardware that the virtual machines will run on sufficiently. Other than that, there should be no issues. b. -------------- next part -------------- A non-text attachment was scrubbed...

[Lustre-discuss] Lustre playground in VirtualBox?
IMHO, one just need 64-bit support Wolfgang Stief wrote:> Hi out there! > > Before I start installing and fiddling around: Are there any reasons > AGAINST setting up a Lustre playground in a VirtualBox environment?

No performance required at all.In fact most of lustre developers use virtualized environments for testing and whatnot. Some use xen for failover testing since it allows to easily attach same "backend storage" to different virtual machines at the same time when both are running (vmware does not allow that, I am not sure about vbox).> Anybody already set up a virtual environment for such a purpose? Any > "best practice" or something?Well, it''s the same as with non-virtualized machines mostly. xen seems to work somewhat faster for me and some others since kernel- level code is executed somewhat faster.

Any > "best practice" or something?The Linux virtio drivers would accelerate guess VM network and disk IO performance if the VM software is capable of making use of it. Not sure about VirtualBox but kvm does support it. You probably don''t care about performance in a virtual sandbox but it''s a low-hanging fruit that comes at little cost. Isaac
