I have had this problem with restoring Proxmox KVM to another server with different VMID
I am now running Pve version 1.9
I used the following steps to create and restore the backup
  1. Suppose I want to backup VMID = 102
  2. Backup a running KVM image using vzdump --dumpdir <dir> --compress VMID onto Proxmox server 1
  3. Copy the *.tgz file to another Proxmox server 2
  4. Copy the *.iso above which the KVM image was created such as debian-live-6.0.3-amd64-standard.iso to proxmox server2 /var/lib/vz/tempalte/iso/
  5. On Proxmox server 2, I run the restore using qmrestore /var/lib/vz/dump/*102*.tgz 107 to restore the backup make in step 2 with different VMID = 107 because VMID 102 is already used on server 2.
  6. I make sure that VM 102 on server 1 is stopped and the onboot flag is not set.
  7. Now I start the restored VM 107 on server 2
  8. I change to a new IP address and hostname, and every thing is OK so far
  9. Now I move to server 1 and start VM 102
  10. I run my ssh session and VM 102 runs for a bit and then it locks up, which behaves like an IP conflict. But the two VM's 102 and 107 are using two different IP's.
I do not understand why it happening. Did I missing to change something? Please help...
Also Is there a butter way?
 
That is it, MAC address conflict
I installed macchanger
Ran ifconfig to view the currently listed MAC-address which is listed as HWaddr
And then ran
macchanger -r eth0 to generate a random MAC-address

Thank you for the help.
 
there is on option regarding MAC in qmrestore, see 'man qmrestore'

Code:
