"kvm acceleration not available" 错误信息解释 "kvm acceleration not available" 错误信息表示KVM(Kernel-based Virtual Machine)加速不可用。KVM 是一种基于 Linux 内核的虚拟化技术,它允许硬件虚拟化,从而提升虚拟机的性能。当系统报告此错误时,意味着虚拟机无法利用 KVM 的硬件加速功能,导致性能可能受到影响。 可...

KVM acceleration can NOT be used 一般情况下 KVM 虚拟机默认不支持虚拟化功能,在 virt-manager 里也不像 VMware 那样可以设置开启虚拟化。这样就导致在 KVM 安装的 EVE-NG 虚拟机里一些模拟的设备不能启动。 (2)物理机支持 KVM,那么 CPU 必然支持 vmx 特性,使用下面命令可以看到 flags 里有 vmx 字样。
I believe the error is not about VT-d (i.e., PCI passthrough) but about VT-x being disabled. What does grep flags /proc/cpuinfo | tail -n 1 show? Does it contain vmx (for Intel, AMD's called svm)? As a work-around you could disable KVM hardware acceleration in VM Options but...
The output of this command is pretty straightforward and clearly indicates whether KVM can be used or not: INFO: /dev/kvm exists KVM acceleration can be used Step 3: Launch a VM In order to launch your first Ubuntu Server 20.04 LTS instance on KVM execute the following command: ...
