Ubuntu 安装libvirt / virt-manager

两者的区别：

  • libvirt是个虚拟化平台
  • virt-manager是libvirt的管理工具（安装virt-manager会默认安装libvirt）

在18.04以及之前版本，安装libvirt，只需要安装libvirt-bin

1
$ sudo apt install libvirt-bin

但是在18.10，libvirt-bin已经被拆分成两部分libvirt-daemon-system和libvirt-clients

1
$ sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils

如果只想安装virt-manager，但又不想安装本地的虚拟化平台，可以执行

1
$ sudo apt install virt-manager ssh-askpass-gnome --no-install-recommends

    # 安装libvirt([qemu在2018年提供了对Hypervisor.Framework的支持](https://wiki.qemu.org/ChangeLog/2.12))
    $ brew install libvirt
    $ brew services start libvirt

    # 安装virt-manager
    $ brew install virt-manager
    $ virt-manager --connect="qemu+ssh://chaos@ubuntu-w510.jeek.club/system?socket=/var/run/libvirt/libvirt-sock"

    # Step 1: Allow your user non-root access to KVM
    ## SSH to the Linux machine and add your SSH user to the libvirt group
    $ sudo usermod -a -G libvirt $(whoami)

    ## Running id $(whoami) should list the libvirt group. You may also need to edit /etc/libvirt/libvirtd.conf to ensure that the socket has the right owner and permissions. Make sure you have these lines in there:
    unix_sock_group = "libvirt"
    unix_sock_rw_perms = "0770"

    # Step 2: Install virt-manager for Mac OS
    $ brew install virt-manager

    # Step 3: Connect virt-manager to the Linux machine over SSH
    ## If you try to tell virt-manager to connect over SSH by just specifying the hostname it might not work though. You'll see an error like End of file while reading data: nc: unix connect failed: No such file or directory: Input/output error. The file it's referring to is the libvirtd socket and the reason it can't find it is because it's looking in the wrong place. It's looking for the sock file in /usr/local/lib but it actually lives at /var/run/libvirt/libvirt-sock (at least it does on Debian). Luckily there's a query param you can pass in the SSH URL to override the socket location:
    $ virt-manager --connect="qemu+ssh://USER@HOSTNAME/system?socket=/var/run/libvirt/libvirt-sock"
