[Lucid Beta2] Wubi hangs on first reboot after installing inside windows on amd64

This might be a VM specific issue, unrelated to Wubi per se'

Passed here on hardware

Steve Beattie and I tried again in VMs and were unsucessful to varying degrees. I suspect that it is, indeed a VM thing as Dave Morley was able to do this on bare metal during the Beta 2 cycle. But that's the only indication I've heard where a Wubi install was successful, so who knows...

I'm only getting the virtual machine crashing behavior; with verbose enabled, the last two lines emitted are:

  [ 3.895512] Write protecting kernel read-only memory: 7680k
  Loading, please wait...

and then, ker-boom, virtualbox throws up a critical error dialog box.

For the record, the last two lines in the virtualbox guest's log are:

  00:00:20.001 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  00:00:20.999 Changing the VM state from 'RUNNING' to 'GURU_MEDITATION'.

Toggling options in virtualbox like enabling IO-APIC don't help.

Oh, this is with virtualbox-ose from the ubuntu archives running on a host with lucid-amd64; the guest was setup as a 32bit win2k install and I was attempting to install wubi from the xubuntu amd64 livecd.

Still no issues here on hw. I'm assuming therefore that it is a vm issue.

Ok... Thanks Dave! I think it's safe to assume that this is indeed a VM issue and not something we can do much about. I'll just refrain from doing Wubi tests until some point when I have enough spare hardware to keep a bare metal windows system around for testing like this.

I have the same problem with the XP host and Ubuntu 10.04 LTS installing via Wubi in the virtualbox (still I could use this VM to boot to Ubuntu easily).
Just freeze at 0 and no kernel loading.
I'm writing a guide using Wubi to install ubuntu but I have no Windows on my computer. Any idea?

It's a i386 system, not just AMD. And no choice in the grub screen could boot at this stage.

It's most likely a problem with running Wubi inside a VM. On bare metal, the Wubi install works fine, as has been tested by several people during the Lucid cycle. It does, however fail to run in VirtualBox. In that case, we've tested it both with Sun's VBox and with -OSE from the repositories, with the same results each time...

I have NOT tried it with VMWare or KVM, however, so there may be a difference there, but at least with VBox, Wubi doesn't work.
