Lubuntu 16.04 LTS SLOW on Mac host
Posted: 30. Aug 2017, 02:59
Hi all,
As the title suggests I'm running Lubuntu 16.04 as a guest (Ubuntu with LXDE). The host computer is a Mac Pro, 8 cores (2 quads) at 2.8ghz with 20gb of ram, Mac OS 10.12.6 (Sierra).
The Guest started out as a 3 core with 4GB of ram, 64mb vram. It took about 2 hours install, and once it was all done, guest additions and all it still runs pretty sluggish. It also takes about 10 min each time for it to boot, which has became infuriating so I've started closing it with a save state. It does pick up a *little* bit, after its booted, logged in, and I don't touch it for a few minutes.
VT-x, PAE/NX, Nested Paging, KVM are all enabled.
I've since then increased the guest to 6 cores, and 9gbs of ram, 128mb vram. It made literally *no difference*. And according to my host, the VM is using a mere 3 to 4gbs, and uses about 10 - 20% of one of my CPUs.
The only thing that helped a bit with the actual usability of the VM was to disable 3d support. I don't remember where, but in my googling I found that post ubuntu 14.something doesn't work well in vbox with 3d support.
The hard disk image is located on a Veracrypt image, but both are fixed, not dynamic. So I doubt that's the issue unless someone has a similar experience?
