使用 virt-install 從命令行安裝 VM

July 25, 2019

免責聲明：

我現在virt-manager用來創建和管理我的虛擬機，它確實是一個救生員。如果主機沒有圖形顯示，它可以遠端使用（從第三台機器，通常是您的工作站）。

我發現的安裝教程中的出現vnc讓我認為“推薦”過程需要主機、來賓或兩者上的 X 東西。絕對不。我的錯。如果您處於相同的情況，請在嘗試從命令行安裝 VM 之前三思而後行。

我正在嘗試在 Debian 主機中安裝 Debian VM，但virt-install我不知道如何將 .iso 映像傳遞給它。

virt-install --connect qemu:///system --virt-type kvm --name prod --ram 6144 --disk /srv/vm/prod.qcow,format=qcow2,size=10 --location=/home/jerome/debian-8.0.0-amd64-netinst.iso --network bridge=br0 --os-type linux --os-variant debianwheezy --extra-args='console=tty0 console=ttyS0,115200n8 serial'

ERROR    Could not find an installable distribution at '/home/jerome/debian-8.0.0-amd64-netinst.iso'
The location must be the root directory of an install tree.
Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
 virsh --connect qemu:///system start prod
otherwise, please restart your installation.
root@versailles:/etc#

我看到的解決方案似乎很扭曲，比如使用 apache 在本地提供 .iso 圖像，就好像它來自遙遠的地方一樣。

Linux Mint 14：通過 CLI（無 GUI）在 KVM 中安裝 Ubuntu 12.10 伺服器
$$ Xen-users $$使用 virt-install 安裝虛擬機（它是 Xen，但看起來還是一樣的問題。

我不敢相信它有那麼複雜。是嗎？

man virt-install說：

If you want to use those options with CDROM media, you have a few options:

        * Run virt-install as root and do --location ISO

        * Mount the ISO at a local directory, and do --location DIRECTORY

        * Mount the ISO at a local directory, export that directory over local http, and do --location http://localhost/DIRECTORY

這不是我在做什麼嗎？

有人說他將 .iso 移到 /cdrom 並且它有效，但我不明白他做了什麼，我無法重現。

我不能在這個問題--cdrom中使用而不是--locationas因為只有在使用.--extra-args``--location

virt-install --connect qemu:///system --virt-type kvm --name prod --ram 6144 --disk /srv/vm/prod.qcow,format=qcow2,size=10 --cdrom=/home/jerome/debian-8.0.0-amd64-netinst.iso --network bridge=br0 --os-type linux --os-variant debianwheezy --extra-args='console=tty0 console=ttyS0,115200n8 serial'
ERROR    --extra-args only work if specified with --location. See the man page for examples of using --location with CDROM media

我想virt-install不支持 Debian netinst ISO 映像--location（但不知何故 Ubuntu 支持？）。

要使用啟動核心--extra-args，virt-install需要具有這些核心和相應的 initrd 文件。 --cdrom只是將 ISO 附加到客戶的 CD 驅動器，這不足以使用--extra-args.

如果您想使用--extra-args，我建議您通過指定最近鏡像的 Debian 安裝程序 URL 來使用“netboot”核心/initrd 文件，如 --location http://ftp.us.debian.org/debian/dists/stable/main/installer-amd64/手冊中所述。

這種方法對我有用：

virt-install --name=centos \
--memory=8196 --vcpus=2 \
--location=/var/lib/libvirt/images/CentOS-7-x86_64-Minimal-1511.iso \
--disk /var/lib/libvirt/images/centos7.qcow2,device=disk,bus=virtio,size=8 \
--network bridge:br0 \
--os-type=linux  \
--nographics \
--extra-args='console=tty0 console=ttyS0,115200n8 serial'
