I can't use KVM and VirtualBox side by side Refer your system's manufacturer manual to enable VT in BIOS. Make sure you have enabled it in your bios. If you want to use another, close the currently running hypervisor and start the other one.Īnother reason for virtualbox guru meditation is VT-x might be disabled in the BIOS. You should run only hypervisor on a single host. Intel VT-x/AMD-V hardware virtualization extensions cannot be used from multiple different hypervisors running simultaneously on the same host. You must use any one hypervisor at a time. So how to fix Virtualbox Guru Meditation error in Linux?Īctually, there is no FIX. Libvirt.libvirtError: internal error: process exited while connecting to monitor: ioctl(KVM_CREATE_VM) failed: 16 Device or resource busyĪfter looking into the Virtualbox forum, I realized that this error occurs if we concurrently run multiple hypervisors at the same time on the same host.

Error starting domain: internal error: process exited while connecting to monitor: ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy I started a VM from virtualbox and then started a KVM guest, but the KVM guest doesn't start. Then I stopped the KVM guest, closed the KVM application and started VM from virtualbox, it worked! Please note that debugging requires special knowledge and tools, so it is recommended to press OK now. Press OK if you want to power off the machine or press Ignore if you want to leave it as is for debugging.
