    Change virtual disk type without a re-install ?

    I may post this in another appropriate forum also. I hope that's okay? I have installed two instances of Ubuntu on VBox using a dynamic VDD setting. Now, I find out through research and advice here, that I may get better performance by allocating a fixed amount of disk space, say 12gigs to each VDisk. Is there a way to change this setting without mirroring the drive, which I don't really follow, or deleting and re-installing the whole VM?

    Thanks

    I have not tried that, but I have ran both dynamic and fixed and really have not noticed a performance difference. This could be because I do not run any taxing loads in a VM. I do usually take the time to do fixed disk, I think it speeds up initial install time, but on my old machines its a slow process either way.

    Googling around, it looks that cloning is the way to go.

    Thanks. I tried to google, but probably didn't enter the right search terms. I read on another thread that if you have the space, which I do, this is a good way to improve performance. But, I've also read that some people don't see a difference.

    You could also try a different search engine.

    Re: Change virtual disk type without a re-install ?

    Thanks again. I meant that I had tried google before posting my original question. The link you provided took me to the right page for this. I'm a little reluctant to take this on that is; cloning and changing sizes and so forth. I'm going to have to get used to a little bit of sluggish behavior. My MacPro, even though older, is so fast to react, I'm spoiled by that.

    Thanks again for your advice and links.

    One last thought

    You could try running a different desktop, may speed it up.

    Code:
    sudo apt-get install gnome-panel
    Reboot and at login, click on the icon in the login window to change desktops.

    I ran this in terminal, installed gnome panel, no problem. When I restarted, I got no login window. I checked, I have auto-login OFF. I shut down and restarted and will see what I get. It seems like it wants to open to the default desktop? So, when I started back up again, it locked and will not completely boot. Just get a blinking cursor. Not a problem. I will figure out to fix it. Not sure what I did?
