linux-VM no nic and not able to install VM-guestAdditions

[Pfeifenraucher]

Hi out there,

i had to upgrade a running host (from omv4 (EOL - debian 9) to omv6 (debian 11)). I set up virtualbox-6.1(.36) again and thought i got all VM up and running - but...
One Linux-VM (bridged, Intel 82540OEM) ran pretty good but now there is no nic availabe. Neither

Code: Select all

lspci -nnk

nor

Code: Select all

dmesg

show any nic - only loopback 127.0.0.1.
I tried to install VBoxLinuxGuestAdditions

Code: Select all

sh ./VBox/LinuxGuestAdditions.run

. Due to md5-checksum-error i cannot get them to be installed. I tried all versions from 6.1 and afterwards 6.0.
This is the first time since vbox2.x i'm not able to repair a vm.

How would you try to solve that issue?

regards

You could copy the tools to the virtual harddisk of the vm first, and try to execute it from there.

Did you try to create a new vm, and use the existing harddisk?

So ovm is the host, and what is the guest unable to connect to the network?
You could temporarily connect to a network using usb (wifi, ethernet or even a phone), maybe updating would help.

Hi David,

thanx for yor thoughts.

You could copy the tools to the virtual harddisk of the vm first, and try to execute it from there.

Ok, that would be cool, but i've actual no idea, which are those tools, nor how to copy them to guest. I managed to start these guets by cli.

Did you try to create a new vm, and use the existing harddisk?

Nope - I'm rying to get phpvirtualbox working with nginx on debian 11.

So ovm is the host, and what is the guest unable to connect to the network?

guest is mld 5.5u based on debian (version ?) as well.

You could temporarily connect to a network using usb (wifi, ethernet or even a phone), maybe updating would help.

Ok, it would be hard, to climb to the top level.

Erik
