SCSI Controller issue to get DHCP IP address

[vkosuri]

Hallo,

Currently, we are facing issue with getting ip address from DHCP server. The operating system we are using Centos OS 7.4, When I used Default(LSI53C895A), SCSI controllers, it went into the Emergency mode.

cat /etc/sysconfig/network-scripts/ifcfg-eth0
BOOTP=dhcp
NAME=eth0
DEVICE=eth0

I changed again it to ViritIO SCSI it booted but unable to get IP address from DHCP server it said

I tail on messages, it says

DHCPOFFER eth0 255.255.255.255 on Port 67
No DHCP offers received

Could you please let us know is SCSI drivers are related to VM interfaces? Any documentation SCSI and VM interface comunications.

Please through some suggestions and advices to resolve this issue.


Here is the hardware details

The scsi controller should be independent of the nic inside the guest!

The problem is more likely in the network setup of the VM
* I would suggest you check the log of the guest of what is happening when it boots up.
* also check whether you see the dhcp requests and replys on vmbr120 in vlan 1124

I hope this helps!

I am new to proxmox Where do i check the logs, file name?

I mostly meant the logs inside the VM

else PVE is based on Debian - so quite a regular linux system - the logs can (for the far greatest part) be found in the journal -> `journalctl -r`
