I am running Ubuntu 16.04 via Virtual Box on my MacBook Pro 2017 w/ TouchBar (3.3Ghz i7, 16 GB 2133 MHZ) and I am getting a very laggy and unpleasant experience on the machine. I have gone through the suggested changes from 7 years ago here: https://superuser.com/questions/172989/virtualbox-running-ubuntu-is-slow-mac-os-x-host

But it does not seem to make a difference. Even when I change the resolution to 720p the performance is still quite poor. Here are the settings for the vm:

    <PAE enabled="true"/>
    <LongMode enabled="true"/>
    <X2APIC enabled="true"/>
    <HardwareVirtExLargePages enabled="true"/>
  <Memory RAMSize="8192"/>
  <HID Pointing="USBTablet"/>
  <Chipset type="ICH9"/>
  <Display VRAMSize="128"/>
  <VideoCapture fps="25" options="ac_enabled=false"/>
      <Property name="TCP/Ports" value="3389"/>
    <IOAPIC enabled="true"/>
      <Controller name="OHCI" type="OHCI"/>
  <StorageController name="IDE" type="PIIX4" PortCount="2" useHostIOCache="true" Bootable="true">

Any thoughts on the settings? I feel like I should be able to get some decent performance out of this machine. (I have tried smaller RAMsizes with no success either). Alternative solutions if this a common Virtual Box issue?


maybe you have not allowed much ram for the virtual machine, or changing one of settings to invalid. Go through the settings once

  • Going through the settings only helps if you know what to look for. What you you recommend regarding RAM given the setup described in the question? – nohillside Aug 3 '18 at 12:23
