[SOLVED] no network after import from vmware

[cazz]

Hi
I did trying now just a little for fun import a VM from vmware into proxmox
I have got almost everything running except I have not network

I have try both with VirtIO and Intel E1000 but no network.

I did try with "sudo ip link set ens18 up" and also add a temp ip "sudo ip addr add 192.168.0.195/24 dev ens18" but no network
It can pink it own IP address but no other machine in the network.

I was wonder if I can trying to install VirtIO drivers into VM (is Ubuntu server 20.04) from ISO file but not sure?

Do you have other VMs with a working network connection?

Could you please share

cat /etc/network interfaces # from host
qm config <vmid> # from host
ip a # from within VM

You can also try to use something like tcpdump -envi ens18 "icmp" to find out where your packages get lost.

Usually VirtIO works out of the box in Linux distributions and E1000 should also work.

I used ovftool yesterday and migrated a bunch of vms.
ovftool vi://root@<esxnode>:/<vmname> .
and then
qm importovf <vmid> pathtoyourvm/pathtovmfile.ovf <storagename>
After that I went into proxmox webgui added a networkinterface and made sure I had the same mac-addr as I was using dhcp for the vms.
And then just simple poweron worked well.

The last command just show that ens18 is down.

When I run tcpdump it say it down so I run then "sudo ip link set ens18 up" and run again and just say it listning on ens18 and nothing more happend.

I was thinking maybe run that and maybe try again.
I did just export VMDK and copy to proxmox and then run "qm importdisk" (I did first create a VM that I later delete harddrive.)

/Update
I run program in my windows but I just get information and nothing more.
it is off, do it have to be on?

Did find the error
At first I have not say where to save the files
And I have to remove my ISO installation from VM.

 

[cazz]

ok I did find the error.
I feel so stupid but when I look in vmware I did notice that interface was ens160 but in proxmox it was ens18
so I did open netplan and change from ens160 to ens18 and reboot.
Now it have IP address and working.

Thanks alot for all the help

I run in to same problem, I had to change the name of the interface in /etc/network/interfaces, it changed during the import, because of that the dhcp server was not started for this interface.

I wrote this just in case somebody hast the same problem and doesn't know what to do with the previous informations.

HI,

I have the same issue. I was able to figure that out for Debian and Centos, but Unbuntu 20.04 and maybe 18.04 as i am about to try. The issue is that the file /etc/network/interfaces is empty. I have been migrating from ESXI 5.5 to Promox 7.

Then i did some more digging and try to change netplan/00-installer-config.yaml

network:
ethernets:
ens32:--changed to ens18
addresses:
- x.x.x.112/27
gateway4: x.x.x.126
nameservers:
addresses:
- 1.1.1.1
- 8.8.8.8
search:
- domain.ca

I rebooted the network, but when i did ifconfig -a there were no addresses at all.

I am not at proficient in Linux so any help would be so welcome

 

[koolandrew]

i found my own answer.

For some reason the formatting is different on proxmox vm vs a vmware vm...i realize this makes little sense.

I changed the following in the file:

nameservers:
addresses:
- 1.1.1.1
- 8.8.8.8

to

nameservers:
addresses: [1.1.1.1, 8.8.8.8]

When changing netplan, you can use sudo netplan try, and it help you out ..

Learning as i go.
