问题

导入到图像的ISO没有大小不能安装为CD

阅读初学者问题，但我不明白发生了什么。

通常，我被要求创建VM并从ISO创建启动。但是通常，当我将ISO添加到图像中时，它会以某种方式添加。它没有尺寸，并且试图将其固定为CD/DVD不起作用 - 因为该图像不能被选中 - 它不在列表中。

图像列表像这样开始。有两个Linux ISO很好，有些服务器2016 ISO可以正常工作。

姓名 描述 类型 尺寸 创造者
Centos-8-Full CentOS 8（完整的ISO） ISO 7.67吉布 -
en_windows_server 2019 v1909.iso Server_2019 ISO - 我@somewhere.com
fedora-workstation-live-x86_64-34-1.2.iso Fedora Linux 34 ISO 1.87吉布 我@somewhere.com

但是我被给予的ISO并被告知是服务器2019的ISO安装ISO。我从图像存储中删除了它并重新添加了它，它仍然没有大小，当您尝试将其作为图像作为图像挂载到更新对话框中的VM时，就不会出现在项目列表中。

我以前看过这一点，永远不知道为什么会发生。

Read beginner question, but I don\u2019t understand what\u2019s going on.<\/p>

Often I\u2019m asked to create a VM and boot from an ISO. But often, when I add the ISO to the Images, it\u2019s added somehow broken. It has no size, and attempting to mount it as a CD\/DVD doesn\u2019t work- because that image is not available to be chosen- it\u2019s not in the list.<\/p>

The images list starts off like this. There\u2019s two Linux isos that are fine, and some Server 2016 ISOS that work fine.<\/p>

But the ISO i was given and told was the installation ISO for Server 2019 doesn\u2019t seem to be that. I deleted it from the image store and re-added it, and it still has no size and doesn\u2019t appear in the list of items when you try to mount it as an image to the VM in the Update dialog.<\/p>

I\u2019ve seen this before and never know why it happens.<\/p>","quoteUsername":"LinuxInside","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@linuxinside除非您上传到Prism处于活动状态的图像，否则它不能用作任何VM的CD-ROM。为什么图像可能不处于活动状态（基本上看不见的尺寸和未活动的图像）的主要原因是因为上传到棱镜的图像是损坏/不完整的。通常，当您使用任何Web浏览器通过本地计算机上传更大的文件大小图像时，通常会发生这种情况。大多数Internet浏览器都具有可以上传到其上传的文件大小的上限，因此上传到Prism的图像可能会被损坏/不完整，这又导致其在群集上保持不活跃。

为了避免这种情况，如果ISO文件大小或磁盘图像大小很大（在GBS中），则建议使用URL方法将图像上传到群集上，而不是通过本地计算机上传图像，因为这种情况不应取决于Internet浏览器限制或本地浏览器可能发生的任何轻微破坏。

请参考配置图像PRISM Web控制台指南中的一节使用URL方法添加图像或使用Prism Central上传图像，请参考添加图像棱镜中央指南中的部分。

@LinuxInside<\/user-mention>\u00a0Unless the image which you upload to Prism is in active state, it cannot be used as CD-ROM for any VMs. The primary reason as to why an image might not be in active state (basically no size seen and image not active) is because the image uploaded to Prism was corrupt\/incomplete. This usually happens when you are uploading larger file size images via your local computer using any web browser. Most of the internet browsers have some upper limit in the file size that can be uploaded to it and so the image which gets uploaded to Prism might be corrupted\/incomplete which in turn causes it to stay inactive on the cluster.\u00a0<\/p>

In order to avoid such scenarios, if the ISO file size or the disk image size is large (in GBs), then it is recommended to use the URL method to upload the image to the cluster instead of uploading the image via local computer since in this case it should not depend on the internet browser limits or any minor disruptions that can happen for local browsers.\u00a0<\/p>

Kindly refer to\u00a0Configuring Images<\/a>\u00a0section in Prism Web Console Guide to add images to Prism using the URL method or if you are using Prism Central for uploading the images, then refer to the\u00a0Adding an Image<\/a> section in the Prism Central guide.\u00a0\u00a0<\/p>","quoteUsername":"Nupur.Sakhalkar","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
