ubuntu 18.04 boxes无法创建虚拟机

[ywmy210]

如题，gnome-boxes无法创建虚拟机，virtualbox没问题。终端启动boxes，创建虚拟机的时候，提示
Unable to start domain: unsupported configuration: CPU mode 'custom' for x86_64 kvm domain on x86_64 host is not supported by hypervisor
这个是什么意思？CPU mode ?
各位大大，有没有了解的？非常感谢！

介绍一下你的电脑的硬件环境，CPU架构


分析：要么是你的主机BIOS中的CPU虚拟化没开。要么使用以下配置。
在你的BOXES虚拟机中使用以下配置。
[x] copy host cpu configuration

1、gnome-boxes --checks
(gnome-boxes:4581): Boxes-WARNING **: 23:50:53.775: util-app.vala:270: Failed to execute child process ?virsh? (No such file or directory)

(gnome-boxes:4581): Boxes-WARNING **: 23:50:53.779: util-app.vala:250: Failed to execute child process ?restorecon? (No such file or directory)
• The CPU is capable of virtualization: yes
• The KVM module is loaded: yes
• Libvirt KVM guest available: no
• Boxes storage pool available: no
Could not get “gnome-boxes” storage pool information from libvirt. Make sure “virsh -c qemu:///session pool-dumpxml gnome-boxes” is working.
• The SELinux context is default: no

2、kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

BIOS中虚拟化是开的。
处理器：Intel® Core™ i5-6200U CPU @ 2.30GHz × 4
显卡：Intel® HD Graphics 520 (Skylake GT2)
gonme：3.28.1 wayland
内存：8GB

无法创建子进程？
libvtr-kvm-guest 不可用？
谢谢各位。

1. https://en.wikipedia.org/wiki/GNOME_Boxes
Boxes uses the QEMU, KVM, and libvirt virtualisation technologies.
1-1. 換句話說 如果你的系統已經安裝/支援 QEMU, KVM, and libvirt 應該是能夠跑 GNOME Boxes

Failed to execute child process ?virsh? (No such file or directory)

Failed to execute child process ?restorecon? (No such file or directory)

1-2. https://help.ubuntu.com/lts/serverguide ... html.en-GB
libvirt

Make sure “virsh -c qemu:///session pool-dumpxml gnome-boxes” is working.

1-3. https://help.ubuntu.com/lts/serverguide/qemu.html.en-GB
Qemu

2. 如果確信已經支援 QEMU, KVM, and libvirt 再參閱這一篇
