Zstack virtual machine can not find hard disk information what to do, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Everything in the production environment of the first job is based on Aliyun, and you don't need to worry about the network, server, etc. Everything in the image has been encapsulated for you, and you can use it directly. After you change your job, you really have too much to learn. The production environment is based on the private cloud environment of zstack, while the development environment is based on the virtualized environment of Vmware. After my former colleague left, the stall was handed over to me. Not to mention the application software, the network structure alone makes people toss about for a long time, coupled with the operating system, application software, MySQL, Redis, Tomcat and what other domain control, dare not imagine how big the hole inside ah?

Recently inadvertently stepped on a landmine, zstack-based private cloud, the creation of a virtual machine, a system disk, a data disk, after normal boot, can only see the system disk, can not see the data disk. Data disk and system disk information of zstackUI interface and virtual machine device management information

According to the following virtual machine device management information, I asked for advice in the relevant technical exchange group. Let me check the driver of the virtual machine and check the driver type in the xml of the virtual machine on the physical machine where the virtual machine is located.

Virsh dumpxml instance-00000042 | grep dev # instance-00000042 hostname or UID information

The result of the command execution is as follows:

Command execution result

According to the analysis of the document, the Great God mainly has the following problems:

1. The second disk is a vdb driver in virtio format.

2. Virtio driver is required for image.

3. The performance of the idedisk is much worse.

Solution: search for virtio drivers

Download address: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso

Software version: virtio-win-0.1.126.iso

Procedure:

1 copy the drive file to the virtual machine

2 mount related files with CD-ROM drive

3. In the device manager, there is a driver such as SC* in the exclamation point state, which can be updated to update the source to select the CD-ROM drive. After the update, the driver is installed successfully! After the disk is processed, it can be formatted and ready for use!

4. Then encapsulate the processed system image into a new image

After reading the above, do you know what to do if the zstack virtual machine can't find the hard disk information? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
