[ale] Ubuntu in VirtualBox

[Michael Campbell]

All,

I've been running Ubuntu 11 in a VM under VirtualBox with no problems for some time now.

Had a quick question I don't know if it's vbox related; is there any (practical) limit to the number of VDIs files (or drives, as it appears to vbox and ubuntu) I can hang on the vbox SATA controller?  Will it just keep assigning /dev/sd[a-z] device files to them? 

Thanks

I think your first bottleneck will be RAM, followed by processor
count, though I can not vouch for the second part, I do not have but
4Gig RAM on either of my test machines.

Sorry, I was unclear.

I'm a developer and I'd like to create a number of VDI's/drives for various versions of tools I use; Db2 version x, version x + 1, Oracle 10, 11, various versions of application servers, etc.   Ideally I'd like to have just that one thing on each VDI, then I can attach whatever versions of things I need for a particular programming job (my company does banking/financial software, so we need to try to use what the banks already have installed and their versions of stuff are all over the place).

So... my question really was, if I have a bunch of VDIs with all this stuff, is there any practical limit to how many I can hang off the virtual SATA controller at a time?  I'm up to 4 right now (/dev/sda through /dev/sdd) and it's working, but if I split this stuff up like I want, I might get up to 8 or so.

Thanks

I do what you are doing and currently I have 5 vdi's without any trouble.  So I guess we should be ok.
