KVM Proxmox VM getting stuck / crashing on PXE boot.

[Kaeltis]

Hey,

I’ve just set up my FOG server using CentOS 7 on ProxMox KVM and tried PXE booting another VM on the same host, connected via bridge.

However no matter what I do (trying different virtual network cards: e1000e, virtio, realtek, CPUs, …), the VM always get’s stuck at the same stage in PXE boot, Proxmox/KVM just shows the VM’s state as “internal-error”.

This is where it get’s stuck:

Edit:
If I use pxelinux.0 it shows some boot menu for about half a second and then only shows a black screen with an underscore at the top and get’s stuck in the same internal-error state.

Three questions

1. Is this vm uefi or bios (legacy) mode?
2. What are your values for dhcp options 66 and 67
3. What version of FOG are you using

It almost looks like this vm target is using iPXE to emulate the PXE rom before it downloads FOG’s version of iPXE (where its stops).

@george1421 This is indeed the issue.

@Kaeltis You may need to look into using Proxmox NIC iPXE ROM from ipxe. Meaning, instead of having the nic use the Proxmox supplied rom file for the nic, have it use a Pure iPXE ROM.

I don’t know the exact steps to do this, but this should at least get you to a starting point.,

Thanks for your help, much appreciated

I followed this https://gist.github.com/papamoose/e0b18d002f8686aaf767 and replaced all three roms, however nothing (not even the version number) has changed, still stuck - maybe they were already up to date?

For the questions:

1. Legacy
2. 66 - 192.168.162.55 (FOGs IP), 67 - undionly.kpxe
3. I followed the CentOS 7 guide from the Wiki, so I’m using the Git trunk.

@Tom-Elliott @george1421

Even tried it on different hardware and with the latest proxmox update now, still no luck.
Any ideas how to get it working?

[Tom Elliott]

I’m fairly sure 4e03a is not the current files.

@Tom-Elliott

The guide i followed was wrong, the files are called efi-XXX.rom, not pxe-XXX.rom.

I updated iPXE and, after that failed, also tried using the updated roms and seabios from qemu’s git repo.
With both attempts however, it get’s stuck at a way earlier stage.

Is there a way to avoid the more recent iPXE versions?

[Kaeltis]

@Tom-Elliott

Okay, it’s a hardware problem. It’s working fine on a proxmox server with a Xeon L5640 but not on one with a L5420.
No clue what do do now, since the working one is in use for something different.

[Tom Elliott]

@Kaeltis THere’s not much I’m going to be able to do.

[Kaeltis]

@Tom-Elliott I guess I have to use one of the physical machines as my master then until the new server arrives.

@Kaeltis So should we mark this solved?

[Kaeltis]

Since this issue isn’t really related to FOG, I’ll mark it as solved.
