N/B: Parallels have since fixed this in the latest version of Parallels Desktop 15, thus it’s no longer an issue
A little while back I tweeted Parallels via their @ParallelsCares twitter account to find out if they could provide support for Parallels Tools with CentOS 8.
RHEL 8 was released 7th May 2019, with Parallels 15 released 13th August 2019, so since CentOS is a free version of RHEL with the commercial, and copyright protected parts removed, I made the presumption that Parallels 15 would support it. However with CentOS 8 taking until 24th September 2019 to be released, all they did was respond to state that they didn’t support it, with a link to their KB article.
I went about looking for a fix, and it turns out it’s fairly easy. It needs two things:
- Pretending to Parallels that what you’re installing is RHEL 8
- The EPEL Repo enabled
Here’s the exactly what I did:
- Download the CentOS DVD image for the version that you want here
- In Parallels, Start the new VM Installation Assistant
- Select “Install Windows or another OS from a DVD or image file”
- Select “Choose Manually”, then “Select a file…”, and find the DVD image you’ve just downloaded
- It will claim “Unable to detect operating system”, click “Continue”
- When the Prompt comes up to select your operating system, select “More Linux” > “Red Hat Enterprise Linux”, then proceed through to creating and booting the VM
- Proceed with the install
- Ensure the network is enabled under “Network & Host Name”
- Ensure the drive is checked in “Installation Destination”
- To fix the error in “Installation Source”, select “On the network” > “http://”, and enter the following in the text box: mirror.centos.org/centos/8/BaseOS/x86_64/os
- Once it’s downloaded the metadata, under the “Software Selection” select the options you want for your install
- Proceed with the install, and make sure you enter a root password
- Once rebooted under a terminal, install EPEL using the instructions here. Ensure you run the command to enable the PowerTools repository too.
- Start the “Install Parallels Tools” process, ensuring that any existing mounted CD/DVD is unmounted. This is needed to mount the Parallels Tools DVD image.
- Run the following commands in a terminal:
mount /dev/cdrom /media/cdrom
- Proceed through the install process for Parallels Tools, and you should be done.
If you want to do this on an existing VM, shutdown the VM, go to Settings > General and change the type (above the VM Name), to Red Hat Enterprise Linux, then boot, and perform steps 9-11 above.
