免责声明:
我现在用它virt-manager
来创建和管理我的虚拟机,它确实是我的救星。如果主机没有图形显示器,则可以远程使用它(从第三台机器,通常是您的工作站)。
我发现安装教程中出现的vnc
使我认为“推荐”过程需要主机、来宾或两者上的 X 东西。绝对不。我的错。如果您遇到同样的情况,请在尝试从命令行安装虚拟机之前三思而后行。
我正在尝试使用 Debian 主机安装 Debian 虚拟机virt-install
,但我不知道如何向其传递 .iso 映像。
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'
Starting install...

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#
我见过的解决方案似乎相当扭曲,比如使用 apache 在本地提供 .iso 映像,就好像它来自遥远的地方一样。
- Linux Mint 14:通过 CLI 在 KVM 中安装 Ubuntu 12.10 服务器(无 GUI)
- [Xen-users] 使用 virt-install 安装虚拟机(这是 Xen,但看起来无论如何都是同样的问题。
我不敢相信事情有这么复杂。是吗?
man virt-install
说:
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
这不是我正在做的事吗?
有人说他将 .iso 移至 /cdrom 并且成功了但我不明白他到底做了什么,我无法重现。
我不能使用--cdrom
而不是--location
像这个问题因为--extra-args
只有在指定时才有效--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 启动内核--extra-args
,virt-install
需要有这些内核和相应的 initrd 文件。 --cdrom
只是将 ISO 附加到来宾的 CD 驱动器,这不足以使用--extra-args
.
如果您想使用--extra-args
,我建议您通过指定最近镜像的 Debian 安装程序 URL 来使用“netboot”内核/initrd 文件,如 --location http://ftp.us.debian.org/debian/dists/stable/main/installer-amd64/
手册中所述。
答案3
区别在于在 iso 文件中所使用的。
virt-install
它与使用的方式无关(--location
与 http URL 一起使用还是--location
与本地 iso 文件的路径一起使用)。
这是使用时有效的命令Debian 在线存储库作为--location
(包括获取输出以完成安装,直到第一次启动(然后需要另外两个步骤才能最终进入新的虚拟机,但这是另一个故事):
virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location http://ftp.at.debian.org/debian/dists/stable/main/installer-amd64/ --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'
您可以采取完全相同的命令,但使用上面提到的Centos ISO 文件as --location
,它也能正常工作(除了与串行控制台的连接一开始似乎不起作用,但原则上安装是使用 --location 和 ISO 文件开始的):
virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location /softwarestorage/CentOS-7-x86_64-Minimal-1511.iso --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'
输出是:
Starting install...
Retrieving file .treeinfo... | 2.2 kB 00:00 ...
Retrieving file vmlinuz... | 9.8 MB 00:00 ...
Retrieving file initrd.img... | 73 MB 00:00 ...
Creating domain... | 0 B 00:00
Connected to domain test8
Escape character is ^]
但如果你使用Debian ISO 文件对于--location
,您会得到错误:
virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location /softwarestorage/debian-8.5.0-amd64-CD-1.iso --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'
Starting install...
Retrieving file info... | 150 B 00:00 ...
ERROR Could not find an installable distribution at '/softwarestorage/debian-8.5.0-amd64-CD-1.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 test8
otherwise, please restart your installation.
依我之见,这证明 Debian ISO 中缺少某些东西/存在任何“错误”(目前不确定我从哪里获得它,但也许有人可以下载一个新的并重复测试...)
