sudo virsh list --all. # to all the VM in the Host Machine sudo virsh destroy <vm-nam> # Stopping or Shutting down the VM sudo virsh dumpxml vm-name > vm-name.xml # Export the VM setting in XML Formate sudo cat vm-name.xml | grep source # to list the attached Partition sudo lvremove /partition/name # remove the LVM Partition sudo rm -rf /RootParition/Centos.img # To remove the .img and .qcow2 partitions sudo virsh undefine <vm-name> # Removing the VM from the Host Machine, before execute sudo virsh vncdisplay # to display the VNC port number How to Connect the Private VM from the Local machine
Host Machine should have the Public and Private Network and VM should configured via bridge network from Privat network.
Using SSH tunnel we can connect the VM, before pls install VNC viewer in your local - https://www.realvnc.com/en/connect/download/viewer/
From Local Machine
ssh -L localhost:5900:VM-IP:VNC-Port-Number username@hostmachine.com For Example
HostMachine: dhanesh.vm-test.com (Public IP)
HostMachine: UserName: dhanesh
VM PrivateIP: 192.168.100.100
VM VNC Port: 12
ssh -L localhost:5900:192.168.100.100:5912 dhanesh@dhanesh.vm-test.com Finally open the VNC viewer and type localhost:5900 you can able to see the VM from your local machine.
Ensure that all the Network settings are working fine.
