For Xubuntu (.). 5 GB of disk space. With Lubuntu, you can use computers with even less memory.I read the above as Xubuntu and Lubuntu both requiring a minimum of 5 GB free disk space. For argument's sake, let's say the free disk space requirement were indeed 5 GB for the regular, non-virtual installation of Lubuntu.
Would a installation (e.g. In, ) then necessarily require 5 GB of real, physical space, too?Back in the day, I worked a little with MS Windoze Virtual PC, but don't recall the ' conversion factor' of virtual to physical disk space; but I'm pretty sure it's not 'unity';). But please do correct me if I'm wrong!!ps: Futher, I'm aware of two installation methods:. I didn't yet check the exact options the alternate installer would offer, e.g. Selecting which programs not to install, thus reducing the free disk space requirement. There is no difference in disk space requirements depending on whether you install Ubuntu on a physical or on a virtual machine.
Here are the steps required to create a macOS virtual machine using Parallels Desktop Lite. Open the Mac App Store on your Mac and search for Parallels Desktop Lite. Click to “buy” it and install it (it’s free). Remaining in the Mac App Store, search for the version of macOS that is installed on your Mac.
I even can't think of a possible reason for those requirements to be different - are bytes only 6 bits when you run on VirtualBox? A sub-question: so the 'conversion factor' of physical to virtual data would indeed be 'unity'.
Thus, that defines the minimum size of the virtual disk: a constraint on the lower bound, so to speak. But regarding the upper bound: the sky's the limit! - a virtual disk could be defined as being (virtually) 100 exabytes in size, even though 'in reality', on the physical disk (say, physically 120 GB in size), it's only been allotted 10 GB, of which Lubuntu would demand = 5 GB physically unused, and 99.9999 virtual exabytes unused. Long-winded, but correct?–Mar 6 '13 at 6:09. This is an oversimplification, so use it with caution.
Data on disk is stored on files. To be able to found this files a Filesystem needs to know it's location, so it must store a table that correlates filenames with it's real position. When you format a partition you are mainly creating this table, this is why you loose some space, i.e. A 1Gb disk becomes 0,9 Gb, it's 'spent' on the table.
The biggest the disk, the bigger this table is. It's quite more to formating and structure, but you I hope you get the idea.–Mar 6 '13 at 18:27. As we can see from your tags you are using Virtual Box for virtualization. Then you can choose a dynamically allocated virtual hard drive:A dynamically allocated file will only grow in size when the guest actually stores data on its virtual hard disk. It will therefore initially be small on the host hard drive and only later grow to the size specified as it is filled with data.So in practise you can give your virtual machine far more disk space than needed, but only those bytes that are really used by the VM are reserved from your remaining hard drive space. This also means that it is of no practical benefit and thus not recommended to go down to the lower limit of system requirements when creating your Xubuntu or Lubuntu VM.In case you are short of memory on your drive consider. installing without a swap.
avoid taking snapshots of your machine. do not 'save the machine state' on power off.
