Virt-manager's virtual resource center

Virt-manager is an open-source virtualization management software shared by RedHat. It is a GUI program written in Python. The underlying layer uses libvirt to manage various hypervisors.

Libvirt seems to be funded by RedHat.

 

Virt-manager can manage virtual machines on multiple hosts. Libvirt must be installed on the host. Because virt-manager is a GUI program of libvirt. Virt-manager needs to use SSH to connect to a remote host.

Run the su command on the computer running virt-manager.
-Switch root to the root account.

Run ssh-keygen
-D: generate the public key and Private Key Required by SSH.
Press enter.

Then ssh-copy-ID-I ~ /. Ssh/id_dsa root @ remothostip copy the public key to the remote host so that the remote host can trust the local host.

Then you can open the remote host link on virt-manager.

 

 

Virt-manager has a feature. The pop-up window allows you to select the ISO, virtual disk, and other resources required by the virtual machine. The dialog box displays "Storage
Pools directory. If you select resources not in this directory. Virtual machines must be faulty.

So this "Storage
Where is the pools directory?
It is/var/lib/libvirt/images/
This directory.

 

If you want to store ISO and Virtual Disks elsewhere, use

Ln
-S your actual directory
/Var/lib/libvirt/Images

Create a hyperlink.

 

 

Now virt-manager is no problem.
 
Virt-Manager supports the vast majority of hypervisor and can be connected to local and network hypervisor. Configurations made by users using GUI in virt-manager are converted to xml configuration files in libvirt and saved in the libvirt directory.

 

Using virt-manager to generate libvirt configuration files is also a good choice. It can generate very complex configuration files.
