Convert Virtualbox To Kvm Drivers For VirtualBox

But when kernel 5.10 was installed there was some issue with compiling the drivers for VirtualBox.

I think there is a workaround out there, but I needed to fix this asap.

I have for now Ubuntu 20.20 on my laptop also get the VMs up and running.

Today I learned that KVM and Oracle VirtualBox doesnt work at the same time.

Up until today, I havent had a chance to use two virtualization applications at a time, so I am completely unaware that KVM and virtualbox doesnt run simultaneously in Linux.

When one of a KVM instance is running, I started a VM from VirtualBox, and it didnt start but showed a error box titled - Virtualbox Guru Meditation.

A critical error has occurred while running the virtual machine and the machine execution has been stopped.

For help, please see the Community section on or your support contract.

Please provide the contents of the log file VBox.log and the image file VBox.png, which you can find in the homeskVirtualBox VMsUbuntu 20.04 ServerLogs directory, as well as a description of what you were doing when this error happened.

Note that you can also access the above files by selecting Show Log from the Machine menu of the main VirtualBox window.

Press OK if you want to power off the machine or press Ignore if you want to leave it as is for debugging.

Please note that debugging requires special knowledge and tools, so it is recommended to press OK now.

I started a VM from virtualbox and then started a KVM guest, but the KVM guest doesnt start.

Intel VT-xAMD-V hardware virtualization extensions cannot be used from multiple different hypervisors running simultaneously on the same host.

If you want to use another, close the currently running hypervisor and start the other one.

Refer your systems manufacturer manual to enable VT in BIOS.

Please remember virtualbox VMs will not start until you turn off all KVM instances.

I love to read, write and explore topics on Linux, Unix and all other technology related stuff.
