SUSE VM mapping problem

207 0 12 6

Sometimes after we created a VM by using the existing SUSE VM image file, actual mappings between network adapters configured for a SUSE VM and Ethernet ports are inconsistent with the supposed mappings in the VM.

For example, you have added three network adapters before creating a VM, and the network adapters are network adapter 1, network adapter 2, and network adapter 3 in sequence.

Mappings between network adapters and Ethernet ports should be:

Network adapter 1 --> eth0

Network adapter 2 --> eth1

Network adapter 3 --> eth2

Actual mappings between network adapters and Ethernet ports in the VM:

Network adapter 1 --> eth3

Network adapter 2 --> eth4

Network adapter 3 --> eth2

Through analysis, we found the reasons as follows: If the network adapter configuration information is retained in the existing SUSE VM image file that is used to create a VM, actual mappings between network adapters configured for a SUSE VM and Ethernet ports are inconsistent with the supposed mappings in the VM.

There is a solution here:

Delete files in the rm –rf /etc/udev/rules.d/*-network.rules directory of the VM adn Restart the VM.
