#7102 fixed 3.2.x No longer PXE Boot Ubuntu 9.04, 9.10, 10.04 Guests - DHCP fails (AFTER PXE has TFTP'd Kernel and initramfs) nickb834
Description

I am no longer able to succesfully PXE boot Ubuntu 9.04,9.10 or 10.04 from my Ubuntu 10.04 server using at least3.2.6.x versions of Virtualbox.

The server itself is configured correctly (I can PXE boot any of the aforementioned Ubuntu versions using either Paralles or VMWare Fusion - ergo server config proved right). I can also PXE boot real machines from this PXE Server.

My Vbox host is Intel MacBook Pro running 10.6.4.

In Virtualbox what happens is the guest pxe boots, receives the kernel and the initramfs, and right at the point before it mounts the root fs over nfs (this is a livecd version of Ubuntu remember) it stops with the following on the console:

ipconfig: /tmp/net-eth0.conf : SIOCGIFINDEX: No such device

That error in and of itself is not a problem, even when the PXE boot works in VMware / Parralells or a real PC that message is always present.

This behaviour occurs no matter which of the Bridged nic types (either of the amds or the three intel versions) I select.

On a working PXE boot (Vmware, parralells, real pc) what should appear next is:

IP-Config: eth0 guessed broadcast address 10.0.0.31

So it appears as if the DHCP offer is not making it back to the guest in Vbox OR the DHCP req is not making it from the guest in Vbox. Which is why my guest hangs.

The very last Sun branded version of VirtualBox definately booted these Ubuntu Live CD's so therefor I am certain that this is a regression since the Oracle branding was applied (though I am not implying that this is the cause!!).

I beleive there is a regression in the networking stack / layer / implementation of Virtualbox.

Through my troubleshooting I beleive I have performed the following:

Proved that the PXE server and NFS server config is correct as VMware, Parallels and Real PC's can PXE boot from it. This proves the media they are booting from (cables etc). Proved that my OS X install is sane. Proved it isnt a Ubuntu bug as Ubuntu 9.04 for eg is over 12 months old without change as it's a live cd - and I used to be able to boot this via PXE with the same server in VirtualBox.

I will endeavour to find the last working version of Vbox such that it is easier to track down what changed between now and then in the portions of the source pertaining to networking.

#6876 invalid 3.2.x does not recognize NVIDIA nForce 10/100/1000 Bryan Christianson
Description

The virtual machine refuses to start under Virtual Box 3.2.x if networking is enabled. If the network is deconfigured the machine runs but is of course not very useful. The virtual machine works fine under VirtualBox 3.1.8

Possibly caused by the host device driver description ending in a trailing space (as seen in the logs)

#6898 fixed 3.2.x results in system hangs / BSODs on XP x64 host Kurt Frank
Description

Initially I thought the 3.2.x series was great, finally the guest hangs/BSODs I was getting with the 3.1.x series were no more. Unfortunately I can't consider trading them in for host hangs/BSODs as a good trade-off.

The hangs/BSODs seem fairly random which made diagnosing the offending application rather difficult, I did so by reverting/uninstalling applications until host stability returned.

I had just gone several days after uninstalling 3.2.0 without further incident when 3.2.2 was released, within an hour of installing it I copped a BSOD.

My best guess is that it has something to do with the network driver as internet facing applications were the ones to hang (Seamonkey, Vuze, Skype) and it does so even if the VirtualBox application is not running.

Specs: Intel Q9450, Gigabyte EP45-DS3R, 8GB DDR2-800, 4* 1TB RAID 10 (ICH10R)

Comodo Firewall 3.14.130099.587, Avast AV (still hangs if uninstalled though), Spybot S&D

So for now I've reverted back to 3.0.12 (the last version without issues).
