Re: KVM, qemu, and virt-manager versus VirtualBox

 

Hi,

Lubuntu Alternate AMD64 dated 15th Sept installed successfully into Virtual
Box. Allocated 512MB RAM and 10GB of Disk Space.

Host machine is running fully updated saucy and Vbox is version 4.2.16 I do
have the extras package installed for VBox.

The VM boots fine, I can access Firefox and the internet and it also closes
down with no issues of hanging / slow speed etc.

Will run a KVM install later this evening with the same iso, RAM and Disk
Space allocations.

Regards,

Phill.
